Modeling Doors

About Doors

Doors can be added in plan, elevation, section or a 3D view. Doors are loadable families, which means that the family of the door (sizes, shapes, design) can be customized and placed in the library to later load them in your project.

Doors are dependent elements on their host which is usually a wall. Like in real life, a door cannot be placed if there is no wall on site. Similarly, in Revit, a door cannot be placed without a wall.

Tutorial Objective:

In this tutorial, you will learn,

Sample Problem:

  • Add doors of following types in the Ground Floor layout as shown below:
    • Door_Single Panel: 0.9 x 2.1 m (all doors except the entrance door)
    • Door_Entrance: 1.50 x 2.63 m (at the entrance of the residence)

M2 Doors Tutorial

Sample Files required for this tutorial:

If you do not have the following files, please download them from here.

  1. “TutorialDoors_Input_LearningRevitOnline.rvt”
  2. Door Family files: “Door_Single Panel.rfa” and “Door_Entrance.rfa”

Solution:

  1. Open tutorial file ‘TutorialDoors_Input_LearningRevitOnline.rvt’ in Revit. This project file already contains walls in the Basement and Ground Floor levels.
  2. Navigate to the floor plan of  “00 Ground Level”.
  3. Doors are loadable families which means we will first need to load the family of the doors from the library (if it is not already loaded in your project).
  4. To load a family into the project:

    • Click Insert tab -> Load from Library panel -> Load Family
    • Navigate to the folder where you have downloaded and saved the Door_Single Panel.rfa (If you do not have this file yet, please download it from here).
      • Note: By default, Revit will navigate to the library where default Autodesk families are stored. If you do not find this path when you need it, try to locate it on your PC at : %ALLUSERSPROFILE%\Autodesk\RVT 2019\Libraries (If you cannot still find the location of your family library, please see this Video Tutorial: Locating your family folder )M2 Doors 1.jpg
    • Select the file and Click Open.
    • The family has been loaded into the project.
  5. Now, before we add the doors into our model, we must create the Door types with the specific sizes as required for our project.
  6. To customize the door sizes and create new door types:

    • Click Architecture tab -> Build panel  -> Door
      • Alternatively, use “DR”as keyboard shortcut.
    • From the type selector, select any of the types available for Door_Single Panel family.
    • From the properties, select Edit Type to access Type properties palette.
    • Click Duplicate to create a new Door Type. In the Name dialog box, give a new name to the door type  “Door_Single Panel_0.9 x 2.1”M2 Doors 2
    • Click Ok to the Name dialog box.
    • Now, change the parameters Width to 0.9m value and Height to 2.1m value.
    • Click OK to the Type Properties dialog box.M2 Doors 3.jpg
    • A new Door type has been created.
    • Click Esc to end the Door tool.
  7. Repeat Step 4 to load the family Door_Entrance.rfa  (If you do not have this file yet, please download it from here).
  8. Repeat Step 6 to create a new door type for the Door_Entrance.rfa family. Name the new Door type as “Door_Entrance_1.50 x 2.63” and change the size parameters to width = 1.50m and height = 2.63mM2 Doors 4
  9.  Now, as all the door types are prepared, we can begin to place doors in the model.
    • TIP: If you are not sure of which type of door types to place in your design, you can always begin by placing doors of any particular type and then later change the door type to a specific one when you have the information. This can be done by simply selecting the door in the model and changing its type from the type selector.
  10. To place a door in the project:

    • Click Architecture tab -> Build panel  -> Door
      • Alternatively, use “DR”as keyboard shortcut.
    • Select the Door type Door_Entrance_1.50 x 2.63 from the type selector.
    • In the drawing area, move your cursor towards the wall where you would like to place the door (between Grid C4-C5 as shown below). Listening dimensions (in blue) will appear to support you to find the position on the wall.
      • TIP: Hover your cursor towards the direction where you would like to set the orientation of the door. The door will flip accordingly. You can also press the Spacebar to flip the door hand from left to right while placing the door in plan view.M2 Doors 5
    • Click on the wall to place the door. Do not worry about the exact positioning of the door or orientation at this moment. You can adjust this after you have placed the door.
    • Click Esc twice to end the Door tool.
    • Note that after placing the door, Revit has made an appropriate opening in the wall automatically.
  11.  Click on the door that you have placed. Flip arrows will appear in the middle of the door. Click on the flip arrows if you wish to change the orientation of the door.
    M2 Doors 6.JPG
  12. We would like to position the door exactly in the center of the two neighboring walls as shown in Fig 1. To do this, the best way is to use permanent dimension and equality constraint.
  13. To adjust the position of an element using permanent dimension and equality constraint:

    • Go to Annotate tab -> Dimension panel -> Aligned
    • On the options bar, select Wall Center line and Pick: Individual References
    • Click the center line of the wall on Grid 4.
    • Click on the center of the Door.
    • Click the center line of the wall on Grid 5.
    • Click on empty space to place the dimension.M2 Doors 7
    • Click Esc twice to end the Dimension tool.
    • Select the dimension that you have placed.
    • There is a small “EQ” sign besides the dimension. Click on this EQ sign.
    • The dimension values will change and display text EQ instead of the values. This shows that the dimensions from the wall center line to the center of the door on both sides have been constrained to be equal. The position of the door has adjusted accordingly. If the wall moves, the door will also move with it to maintain the equal distance to its center. M2 Doors 8.JPG
    • Click Esc to deselect the dimension.
    • If you delete the dimension, a warning sign will be displayed explaining that equality constraint between the elements will be maintained even when the dimension is deleted. Say OK if you wish to do so. If you do not want the equality constraint to be maintained, then select Unconstrain. M2 Doors 9.JPG
  14. Now, repeat step 10 to place the door type “Door_Single Panel_0.9 x 2.1” near Grid F-2 as shown below.M2 Doors10.jpg
  15. Use temporary dimensions to adjust the position of the door:

    • Select the door after placing it. Temporary dimensions will appear. Click on the temporary dimension’s value and change it to 0.7m  as shown below to place the door 0.7m away from the wall on Grid G.
      • Drag a control for the witness line (the blue dots shown in the image) to a different reference, if needed (for ex: from center of the wall to face of the wall)
      • Alternatively,  right-click the witness line control, and click Move Witness Line. You can then move the witness line to a new reference.
        M2 Doors11
  16. Now, repeat step 10 to place the door type “Door_Single Panel_0.9 x 2.1” as shown below.M2 Doors12
  17. Now, for this door, we would like to position the right door frame attached to the right wall. To do this, the best way would be to use Move tool.
  18. Use Move Tool to adjust the position of the door:

    • Go to Modify tab -> Modify panel -> Move
      • Alternatively, use “MV” as a keyboard shortcut.
    • Click on the edge of the right door frame as the base point.
    • Click on the edge of the wall where the door frame needs to be moved.

      After the door has been moved, click Esc to end the Move tool.

  19. Now, repeat step 10 to place the door type “Door_Single Panel_0.9 x 2.1” as shown below. M2 Doors15
  20. Adjust the position of the door on Grid K using the Move tool as shown in step 18 to align the door frame with the wall.
  21. Now, the door on Grid I is exactly at the same parallel position as Grid K. To align both of these doors, use Align tool.
  22. Use Align tool to adjust the position of the door:

    • Go to Modify tab -> Modify panel -> Align
      • Alternatively, use “AL” as a keyboard shortcut.
    • Click on the center line of the door on Grid K to set it as a reference.
    • Now, click on the center line of the door on Grid I to align with the reference.M2 Doors16
    • Both doors are now aligned with each other.
    • Click Esc to end the Align tool.
  23. Using the methods shown above in step 10, 15 and 18, place doors with door type “Door_Single Panel_0.9 x 2.1” as shown below:M2 Doors17
  24. Navigate to a 3D view to see all the doors in 3D.M2 Doors 18
  25. After completing all the steps above, Save As your project as “TutorialDoors_Output_LearningRevitOnline.rvt”.

More References:

  • After placing the door, if you would like to move it to another wall, use ‘pick new host’ tool to move the door.
  • If you would like to create your own custom family for the door, it is advised that you first familiarize yourself with basic family editing tools covered in later sections of this course. However, if you are already familiar with them, you can create a custom door as guided by this Video Tutorial: How to create a door family presented by Brett Grinkmeyer.

Modeling walls using CAD reference

Make sure that you have completed the Tutorial Import a CAD drawing and Modelling Basic Walls, before moving on with this tutorial.

Tutorial Objective:

In Modelling Basic Walls chapter, we learnt about modelling basic walls, Trim/Extend Tools and using dimensions for modeling purposes. Please make sure that you are familiar with these tools as well as how to Import/Link a CAD drawing, before starting with this tutorial.

In this tutorial, you will learn,

Sample Problem:

  • Add walls for the Ground Floor of the sample project as shown below. Use the  linked/imported CAD drawing “Ground Floor Layout_For Import.dwg” as reference. (as imported in previous chapter Import a CAD drawing).
M2 Import wall Tutorial.JPG

Fig 1. Walls in the Ground Floor Layout of the Sample project

Sample Files required for this tutorial:

If you do not have the following files, please download them from here.

  1. “TutorialWallsCAD_Input_LearningRevitOnline.rvt”
  2. “Ground Floor Layout_For Import.dwg”

Solution:

  1. Open ‘TutorialWallsCAD_Input_LearningRevitOnline.rvt’ in Revit. This project file already contains “Ground Floor Layout_For Import.dwg” imported into the floor plan view of  “00 Ground Level”. It also contains the basic wall types required for the project.
  2. Navigate to the floor plan of  “00 Ground Level”. Notice the Imported CAD drawing in the view.
  3. Now, before modelling walls, let’s hide the layers of the CAD drawing which are not necessary for us at the moment.
  4. To hide layers of the CAD file:

    • Go to View tab -> Graphics panel -> Visibility Graphics -> Visibility Graphics Override dialog box will appear.
      • Alternatively, use “VG” as a keyboard shortcut.
    • Go to Imported Categories tab.
    • Expand the row with the name of the CAD file:  Ground Floor Layout_For Import.dwg
    • The list of all layers available are present.
    • Turn off the checkbox for layers you do not need. For example, furniture layer with the name “FUR”. M2 Import wall 8
    • Say OK.
    • You will notice that the elements present in the FUR layer (Furniture) is turned off in the drawing area.
  5. If you do not know which elements are in which layer, you can also use Query tool to identify and hide the layers.
  6. To query a CAD file:

    • Select the CAD file in the drawing area.
    • Under Modify tab-> Import Instance panel -> select Query
    • Select the part of the CAD file for which you would like information. For example, select the text in the Grid bubble of the CAD file as shown below. M2 Import wall 9
    • Import Instance Query dialog box will appear showing the information of the selected element.
    • Choose “Hide in View” to hide the shown layer from the drawing area.
    • Continue to make further queries, if you like.
    • After completing, Click Esc to end the Query tool.
  7. Using Steps 4 and 6, turn off all layers except layer “wall”(for walls) and “dw”(for doors and windows). M2 Import wall 10
  8. Now, let’s create the walls of the kitchen room between Grid C-2 and G-4.
  9. First, we will have to know the wall thickness/wall type required.
  10. Use dimension tool to know the wall thickness.
  11. To place a dimension:

    • Go to Annotate tab -> Dimension panel -> Aligned
      • Alternatively, use “DI”as a keyboard shortcut.
    • Click the line (of the CAD file) at the face of the wall.
    • Click on the other face of the wall for which dimension is needed.
    • Click in an empty space to place the dimension.
    • In this case as shown below, the wall thickness is 230mm/0.23m M2 Import wall 11
  12. Now, there are two ways to model walls. One is to sketch the wall in a rectangular/striaght line shape snapping on the CAD lines. The other is to use ‘Pick line’ tool. Let’s learn both.
  13. At this point, ignore the openings for Doors and Windows. When Doors and windows are modeled, openings will be made automatically by Revit in the walls.
  14. To sketch walls by snapping on the CAD lines:

    • Click Architecture tab -> Build panel -> Wall drop-down -> Wall: Architectural
      • Alternatively, use keyboard shortcut ‘WA’.
    • From the Type Selector, select ‘230mm Brick Masonry’ wall type.
    • From the Draw panel, select Rectangle as shape.
    • On the options bar, select Location Line as the Core Face Exterior as we want to match the exterior brick face of the wall to the outer rectangle in CAD. (Learn more about Location Line here).
    • On the options bar, Set the Height constraint to “01 First Floor Level”.
    • Enter the start and end point of the rectangle by snapping on the CAD lines as shown below.M2 Import wall 12
    • The rectangular wall has been created.
  15. Let’s model walls between Grid B-5 to E-9 using ‘Pick Lines’ tool.
  16. To model walls using Pick Lines tool:

    • Click Architecture tab -> Build panel -> Wall drop-down -> Wall: Architectural
      • Alternatively, use keyboard shortcut ‘WA’.
    • From the Type Selector, select ‘230mm Brick Masonry’ wall type.
    • On the options bar, select Location Line as the Core Face Exterior as we want to match the exterior brick face of the wall to the outer rectangle in CAD. (Learn more about Location Line here).
    • On the options bar, Set the Height constraint to “01 First Floor Level”.
    • From the Draw panel, select ‘Pick Lines’ tool.
    • In the drawing area, select the edge/line of the CAD file as shown below where you would like to place a wall. A blue dotted reference line will be shown while you try to select the line – to show in which direction the wall will be placed. Keep your cursor towards the direction where you want to place the wall and then when the dotted reference is showing correctly, click to place the wall. M2 Import wall 14
    • The wall has been placed of the length equal to the line selected.
    • Similarly, select lines/edges in all four directions of the room – as shown below.
      • TIP: . In CAD, lines that you pick may not represent the actual length of the wall. Instead of picking multiple lines and create more instances of the walls along the length of the wall, use Trim/Extend tools to reduce the number of Instances.M2 Import wall 15
    • Using Trim/Extend to Corner tool connect all four walls in a rectangular shape.
      • Go to Modify Tab -> Modify Panel -> select Trim/Extend to Corner
        • Alternatively, use keyboard shortcut ‘TR’.
      • Click on the two walls between which a L Corner is needed to be created.
    • A rectangular wall between Grid B-5 to E-9 has been created.M2 Import wall 16
  17. Now, let’s create more walls between Grid G-2 and K-4.
  18. Using Pick Lines tool (as shown in step 16), create walls of 230mm wall type on vertical Grid I and K as shown below.M2 Import wall 17
  19. Using Trim/Extend to Corner tool connect the wall on Grid 2 with Grid K.
    • Note on Best Practice: Now, instead of creating an additional horizontal instance on Grid 2, it is better to use Trim/Extend to Corner tool to extend the length of the wall to connect with the vertical walls added in the previous step 18.
  20. Using Pick Lines tool (as shown in step 16), create walls of 230mm wall type on horizontal Grid 3 and 110mm wall type on the partition wall located slightly above Grid 3 as shown below.M2 Import wall 18
  21. Using Trim/Extend Multiple Element, extend these walls towards the vertical wall on Grid I.
  22. To Trim/Extend Multiple Element:

    • Go to Modify Tab -> Modify Panel -> select Trim/Extend Multiple Element
    • Click on the vertical wall on Grid I to define the border for extension.
    • Click on the horizontal walls around Grid 3 that needs to be extended.
    • A Tee-Junction has been created between these walls.
    • Click Esc to end the tool.M2 Import wall 19.JPG
  23. To draw other walls on the Ground Floor layout as shown below, use either the sketch walls (as shown in step 14) or Pick Lines tool (as shown in step 16). Reduce the number of instances by using Trim/Extend tools. M2 Import wall 20.JPG
    • TIP: Switch to “Shaded” visual style to clearly see where the walls have been already modeled.
      • Go to View Control Bar -> Visual Style -> Graphic Display Options -> ShadedM2 Import wall 21.jpg
  24. After completing modeling all walls, you may choose to hide the imported CAD file to see the Revit model clearly.
  25. To hide the imported CAD file,

    • Go to Visibility Graphics (“VG”as a keyboard shortcut).
    • Go to Imported Categories tab -> Select the Imported CAD file and turn off the checkbox beside the name of the CAD file.M2 Import wall 22.JPG
    • Say OK.
  26. The CAD file is now hidden from the view. If you want, you can repeat the step 25 and turn on the checkbox in the visibility graphics to unhide the imported CAD file.
  27. After all the walls are created and if you do not need the imported CAD file, you may select and delete it from the project.
    • TIP: If you have linked your CAD file, then you may unload the link by going to Insert -> Manage Links -> CAD Formats -> Unload. When you need the file again, you can Reload it in the project. If you are sure that you do not need the linked file again, then you can also remove it instead of unloading it.
  28. Navigate to a 3D view to see all the walls in 3D. M2 Import wall 23.JPG
  29. After completing all the steps above, Save As your project as “TutorialWallsCAD_Output_LearningRevitOnline.rvt”.

Import/Link a CAD drawing

About Using CAD drawings in Revit

Some architects like to begin their design in CAD software tools. CAD drawings are then imported/linked in Revit to be used as references/underlay. REVIT model geometry is then built by tracing over elements in CAD file. Another popular reason to import CAD files into Revit is to use them for detailing purposes. If you already have some details drafted in CAD, you may import them in Drafting view and use them in Revit.

You can either import a CAD file or you can link it. If you expect the CAD file to change, it is best to link it. If the CAD file is revised, then you can simply reload the linked files in Revit and see those changes. However, if you do not expect the CAD file to change, it is best to Import it. Importing a CAD file will increase the size of the Revit project file, but in turn will use less memory.

Tutorial Objective:

In this tutorial, you will learn,

Sample Problem:

  • Link a CAD file containing the Ground floor layout of the sample project into Revit and place it on the “00 Ground Level” Floor Plan as shown below.

M2 Import Tutrial.jpg

Files required for this tutorial:

If you do not have the following files, please download them from here.

  1. “TutorialImportCAD_Input_LearningRevitOnline.rvt”
  2. “Ground Floor Layout_For Import.dwg”

Solution:

  1. Make sure that you have the CAD file “Ground Floor Layout_For Import.dwg”  and have prepared it as per the tips in step 2.
  2. Prepare CAD file before importing:

    • Open your CAD program and make sure you have done the following:

    • Have only those geometries/layers in the CAD file which are necessary for you to use in Revit (this will reduce the file size and the memory required in Revit). You may also choose to Freeze the layers which are not required.
    • Many CAD users like to put layouts, elevations, sections, etc all in one CAD file. Do not crowd multiple drawings in one CAD file while importing in Revit. For example, if you are importing a layout drawing of a particular floor, try to have only that layout in the CAD file. If necessary, copy the geometry you would like to import and paste it into a new CAD file, to avoid any unnecessary references.
    • Purge your file before importing.
    • Check if drawing units and file units are consistent.
    • If you need Xrefs, then bind them in your drawing. If you do not need them, unload/remove them.
    • Copy the original file before modifying for import. Just in case, if you need to get back to the original version.
    • Open the tutorial file ‘TutorialImportCAD_Input_LearningRevitOnline.rvt’ in Revit. This project file already contains model geometry for basement floor, grids, levels and section views.
    • Navigate to the floor plan of  “00 Ground Level”.
    • Go to Insert tab -> Link -> Link CAD (If you would like to import a CAD file not link it, you may chose to go to Insert tab->Import-> Import CAD)
    • A Link CAD Formats dialog box will appear. Use following Settings:M2 Import 1
      • Check the “Current View Only” checkbox if you want this CAD file to be visible only in the view it is being imported (Ground Level Floor Plan). If you do not check this box, the CAD file will appear in all views, including 3D views.
      • Colors: Preserve (if you want to preserve the colors of the layers in CAD file).
      • Layers: All (If you choose to import only visible layers in CAD or choose Specify option if you would like to import only selected layers. The selection option will appear during the import process).
      • Import Units: “Ground Floor Layout_For Import.dwg” used for this tutorial has been created in Imperial Units (Inches) while the model in Revit is being created in Metric Units. To import this file correctly, choose “Inch” in the Import units.
      • Positioning: Auto-Center to Center (this will place the center of the CAD file to the center of the Revit view). Choose other options if you would like to place the CAD file Origin-Origin / By Shared Coordinates.
      • Place at: 00 Ground Level is seelcted by default as we are trying to import the CAD file in the active view.
    • After selecting all the Settings as above, click Open. This will import the CAD file in the view.
  3. However, note that CAD file imported is not at the correct position.M2 Import 2
  4. To move the CAD file to the right position, use Move tool.
  5. To Move,

    • Select the object (in this case, the imported CAD file).
    • Go to Modify panel -> Modify -> select Move tool.
      • Alternatively, use “MV” as a keyboard shortcut.
    • Click to enter move start point. In this case, it would be the top left corner intersection of the center line in the CAD file. This will be the base point for moving the CAD file.
    • Click to enter move end point. In this case it would be the intersection of Grid 1-A. M2 Import 3
    • Click Esc to end the Move tool.
  6. Once the position of the CAD file is correct, it is best to PIN it. It will prevent you to move/ delete the file by mistake.
  7. To Pin the CAD file:

    • Select the CAD file.
    • Go to Modify panel -> Modify -> select Pin tool.
      • Alternatively, use “PN” as a keyboard shortcut.
    • The CAD file is now pinned.
    • Click Esc to end the Pin tool.M2 Import 4
      • NOTE: If you would like to Unpin the CAD file,
        • Select the CAD file.
        • Go to Modify panel -> Modify -> select UnPin tool.
          • Alternatively, use “UP” as a keyboard shortcut.
        • The CAD file will be unpinned.
  8. To give the visibility of an Underlay for the CAD file (in order to avoid confusion between Revit model geometry and visible geometry of CAD file), the imported geometry can be set to halftone or some of the layers can be turned on/off.
  9. To control the visibility of the CAD file:

    • Go to View tab -> Graphics panel -> Visibility Graphics -> Visibility Graphics Override dialog box will appear.
      • Alternatively, use “VG” as a keyboard shortcut.
    • Go to Imported Categories tab.
    • Check the checkbox for halftone.
      • TIP: To turn on/off particular layers, use checkbox besides the layer names.M2 Import 5
    • Click Ok.
    • Note that the CAD file in the drawing area is now grey/halftone. M2 Import 6
  10. As we have linked the CAD file, it will be possible to see the changes if the CAD file is updated by reloading it.
    • Go to Insert tab -> Link panel -> Manage Links -> Manage Links dialog box will appear.
    • Go to CAD formats tab.
    • The linked CAD file will be listed here. Select the row of the linked CAD file.
    • Click Reload to reload the file from the same path.
    • Use Reload From… option if the path of the file is changed.
      • If you would like to unload the file from your project, choose Unload. You can at a later stage, use Reload to reload it in your project.
      • If you would like to completely remove the file from your project, choose Remove. You cannot Reload the linked CAD file, if you have removed it. You will need to link the file again. M2 Import 7
  11. After completing all the steps above, Save your project file.

Adding Section Views

About Section Views

Section views cut through the model at a cutting plane specified and show a 2D  orthographic projection in the view. Creating section views in a CAD program requires a lot of manual effort. Whereas, in Revit, creating a section view is automated saving significant time and energy. It is as simple as drawing a line to specify the section plane and that’s it! Because the modeled elements in Revit are 3D, the software is able to create their 2D projection along the specified plane automatically. If any building elements are revised, added or removed in the building model, the changes are also reflected in the section views automatically – saving a lot of time, money and energy in coordination of all drawings.

Tutorial Objective:

In this tutorial, you will learn,

Sample Problem:

  • Create a vertical section with a split segment
  • Create a horizontal section with a break line
  • Hide Grid lines from the section view
  • Hide surface pattern of the wall in the section view

  3. Now, let’s create a vertical section line as shown in Fig 1.
  4. Add a section View:

    • Click View tab -> Create panel -> Section
    • From the Type selector, select ‘Building Section’ type.
    • In the drawing area, place the cursor at the starting point of the section, and drag through the model. Click when you reach the end point of the section.
    • The section line has been created. M2 Section 1
    • Click Esc to end the section tool.
      • TIP: Click on the section line -> Click on the Flip arrow beside the section head to flip the direction of the section view.
    • Double Click on the section head (the blue bubble like symbol), to go to the section view.
      • Alternatively, click on the section line -> right click -> Go to View
      • Alternatively, navigate to the project browser -> Under Sections -> Double click on the name of the section view to open it.M2 Section 2
  5. When you open the section view, you will notice that building elements are shown as cut from the section line that you drew in the layout.
  6. To rename the section view:

    • Go to the project Browser -> Right click on the section view you would like rename -> On the right click menu, go to Rename -> Change the name of the view and press Enter.
      • Alternatively, click on the section line in the drawing area -> Go to properties -> Under Identity Data -> View Name parameter -> Change the name of the view and press Enter.M2 Section 6
  7. Using the Crop and Far Clip Offset, you can adjust which elements are included in your section view and which are excluded from it. Use the following procedure to adjust the width (crop) and the depth(far clipping) of a section view.
  8. Adjust Crop Boundary and Far Clip Offset of a section view:

    • Navigate to the floor plan of “-01 Basement Floor Level”.
    • Click on the section line that you added in step 3.
    • Notice a blue dotted line in front and on sides of the section line.M2 Section 4
    • The dotted line in front and parallel to the section line is the far clip offset plane which control the depth of the view. Only those elements are displayed in the view which are within the boundary line of far clip offset plane. Use the blue arrows to adjust the boundary.
    • The dotted lines on sides control the crop region (width) of the section view. Only those elements are displayed in the view which are within the boundary line of crop region. Use the blue arrows to adjust the boundary.
    • You can also adjust these parameters from the properties of the section line. Click on the section line -> Go to Properties -> Under Extents -> Notice the Crop and Far Clip Offset settings.M2 Section 5
    • To control the display of elements when they are cut at the far clip plane, adjust the Far Clipping options. Learn more about this Setting here.
    • Adjust the Far clip plane and Crop boundary of the section view and then go to the section view to see how the impact of those adjustments.
  9. To control which elements to display and which to turn off in a view, use Visibility Graphics Settings.
  10. Turn on/off elements in a section view:

    • Visibility Graphics allow you to hide/show element categories in a specific view. For example, let’s say that we want to turn off all the Grid lines from the section view.
    • Open a Section view from the project browser.
    • Go to View Tab -> Graphics panel -> Visibility / Graphics
      • Alternatively, use keyboard shortcut “VG”.
    • A list of all Revit categories are displayed.
    • As Grids are annotation elements. Go to Annotation Categories tab. Scroll down from the list of categories to find Grids. There is a checkbox besides the Grids category. Turn it off. M2 Section 7
    • Say OK.
    • Note that all Grid lines in the view are hidden now.
    • To turn them back on, go back to Visibility /Graphics and turn the checkbox on besides the Grid category.
  11. Visibility/Graphics settings can also be used to control how elements are displayed when in a projection and cut in a section.
  12. Adjust Project/Cut display of elements in a view:

    • Let’s say that we want to turn off surface patterns of walls that are displayed in the section view as shown in the image below.M2 Section 3
    • Go to View Tab -> Graphics panel -> Visibility / Graphics
      • Alternatively, use keyboard shortcut “VG”.
    • A list of all Revit categories are displayed. As Walls are model elements, go to Model Categories list and scroll down to Walls category.
    • Under Project/Surface -> Patterns -> Click on Override -> Turn off the Foreground pattern by switching off the Visible checkbox.M2 Section 8
    • Click OK to Fill pattern Graphics dialog box.
    • Click OK to Visibility / Graphics Override dialog box.
    • Note the change in the section view. The brick pattern of the walls shown in projection are turned off.M2 Section 9.JPG
  13. Go back to the floor plan of  “-01 Basement Floor Level”. Repeat step 4 to add a horizontal section as shown in Fig 1. By default, the name of the section view will be “Section 2”, continuing the number sequence from the previous section. Follow Step 6, if you would like to rename the section view. Repeat Step 8, to adjust the far clip offset and crop boundaries as shown in the image below.M2 Section 10
  14. Sometimes for presentation purposes, you may not want the section line to appear across the entire drawing. In this case, the section line is required to be displayed as broken lines instead of one continuous line.
  15. To break a section line:

    • Click the section line of Section 2 (section line you created in step 13).
    • Notice the break control symbol on the line.
    • Click on the break control symbol to break the section line.
    • The section break is in the middle of the section line. The following images show the same section, whole and broken.
    • To rejoin the section line, click the break control again.
    • A break in a section line is view-specific. It affects the display of the section only in the view where the break was made.
  16. If you would like to split the cutting plane of the section view in order to show two different areas of the model, you can use ‘split segment’ tool.
  17. To split section line segment:

    • Click on the section line of Section 1 (vertical section line created in step 4).
    • Go to Modify|Views tab -> Section -> Split Segment
    • Click on the section line from where you would like to begin the split.
    • Move your cursor in the direction where you would like to position the split segment. Click where you want to place it.
    • A section line has been split.
    • Click Esc twice to end the Split Segment tool.
    • Click on the section line again.
    • Using the arrows on the section line, you can adjust the split segments, if necessary.M2 Section 12
    • Go to the view and observe how the view is revised after the split segment.
  18. After completing all of the above steps, Save As your project as “TutorialSectionView_Output_LearningRevitOnline.rvt”

TIPS

  • TIP: Custom Section Tag

The type properties of the section line specifies which section tag to use. The Section tag contains a section head and a section tail. Both, the head and the tail, are symbols that can be selected from the properties of the section tag.

To customize the section tag symbol, a section head family needs to be created and then added to a section tag.

Building Information Modeling

Traditionally, the building industry delivered the building projects with manually created drawings on which the information was added by using notes and specifications. With the advance of CAD (Computer Aided Design and Drafting), this process was made more efficient. However, the methodology remained the same. Drawings became computer-based and the information was added on using paper-based pile of specifications and notes. These methods often resulted into uncoordinated, inaccurate and missing set of documentation.

Now, developments in Building Information Modeling (BIM) methods have brought a new perspective on how projects can be managed in the building industry. Here, the information plays a central role in developing 2D and 3D representations of the building model. Both information and the building model are interconnected. As the project progresses from concept towards execution and then operations, information keeps updating and so does the building model. This way, the BIM model becomes a repository of integrated and coordinated set of documentation for the project at the given stage of the project life cycle.

Thus, Building Information Modeling can be understood as a building design and documentation methodology that integrates coordinated, reliable information about a project from design through operations. The Autodesk® Revit® platform is purpose-built software for building information modeling.
