Add Grids

About Grids

Grids are Datum elements used for marking the alignment for the structural elements (columns/structural walls) in a building design. Grids consist of Grid line and Grid symbol. Grid lines can be controlled from Grid properties. Grid symbols can be customized by creating a custom Grid head family.

Tutorial Objective:

In this tutorial, you will learn to,

Sample Problem:

Add Grids in the sample tutorial project as shown below:

  • Vertical Grids from A-M at distances shown in Fig 1.
  • Horizontal Grids from 1-10 at distances shown in Fig 1.

Sample File required for this tutorial: “TutorialGrids_Input_LearningRevitOnline.rvt” (If you do not have this file, please download it from here.)

M2 Grid 6

Fig 1. Grids for the tutorial sample project

Solution:

  1. Open the tutorial file TutorialGrids_Input_LearningRevitOnline.rvt in Revit. This project file already contains the site boundary line created in previous chapter Sketch Lines.M2 Lines 6
  2. From the Project Browser, navigate to the Floor plan view named “00 Ground Level”.
  3. Add a new Grid:

    • Go to Architecture tab -> Datum panel -> Grid
      • Alternatively, use “GR”as the keyboard shortcut.
    • Click Modify | Place Grid tab -> Draw panel -> Select a straight line option.
    • Let’s start by drawing Grid A as shown in Fig 1. Grid A is located at the left vertical boundary line of the site.
    • Click the start point of the Grid at the top left intersection of the site boundary lines in the project.M2 Grid 2
    • Move the cursor downwards vertically. Click to enter Grid end point where you want the Grid line to end.M2 Grid 7
    • Click Esc twice to end the Grid tool.
  4. Select the Grid line.
  5. In the Grid symbol, click on the text to change the Grid name from 1 to A. Alternatively, go to properties of the Grid line and in the Instance parameter Name, change the value from 1 to A. M2 Grid 8
  6. While the Grid line is selected, you may notice the two node like circles at both start and end point. Clicking and dragging these nodes, you can extend the Grid lines. Click and drag the node symbol of the Grid A and extend the grid line away from the site boundary lines.M2 Grid 9
  7. Click Esc to deselect the Grid.
  8. Now, let’s create Grid B as shown in Fig 1. Grid B is located at 3.61m away from Grid A. The best way to create this Grid is to offset Grid A at the specified distance.
  9. Offset a Grid:

    • Go to Architecture tab -> Datum panel -> Grid
      • Alternatively, use “GR”as the keyboard shortcut.
    • Click Modify | Place Grid tab -> Draw panel -> Select Pick Lines tool.
    • On the options bar, specify offset value as 3.61mM2 Grid 10
    • Hover your cursor on Grid A. Revit will show you a dashed blue reference line where the offset will be placed. Click if the position shown by the reference line is correct.
      • TIP: Hover slightly towards right of Grid A to guide Revit to offset towards right side. Similarly, hover your mouse slightly towards left to guide Revit to offset towards left side. The direction will be indicated with a dashed blue reference line showing the position where offset will be placed.
  10. Grid B is added in the drawing. The length of the Grid line is exactly the same as the Grid A as we have used offset tool.
    • Note that the Grid has automatically taken the name “B”. In Revit, Grid numbers are given automatically based on the last number of the Grid that you have specified. However, if you change the value of the grid after it is placed, other already placed grids do not change their value automatically. The change only affects the new Grids.
  11. Using the Pick Lines and Offset method shown in step 9, add Grids C to M with specified distances as shown in Fig 1.M2 Grid 12
  12. All Vertical Grids are added in the project.
    • Tip: If more than one grid lines are already aligned with each other, a small lock sign will be displayed. When the alignment is locked between these Grids, extending one Grid line would automatically extend all other grid lines that are aligned with it. Try to extend the vertical grid lines from A to M as they are already locked in alignment with each other, if you extend one grid line, all other grid lines would also be extended together.
  13. Let’s create Horizontal Grids now.
  14. Add a new Grid:

    • Go to Architecture tab -> Datum panel -> Grid
      • Alternatively, use “GR”as the keyboard shortcut.
    • Click Modify | Place Grid tab -> Draw panel -> Select a straight line option.
    • Grid 1, as per Fig 1, is located at the Top Horizontal boundary line of the site.
    • Click the Start point of the Grid line at the top left intersection of the boundary lines. Move the cursor in horizontal direction and Click the End point of the Grid line where you want the line to end.M2 Grid 13
    • Click Esc twice to end the Grid tool.
  15. A new horizontal grid has been added and is automatically named as Grid N as the numbering continues from the last Grid line name.
  16. Select the Grid N. Go to its properties and change the Name from N to 1. Press Enter. Alternatively, you can also click on the text inside the Grid symbol and change the value from N to 1.
  17. Click and drag the node like circle on the start point of the Grid 1 and extend the grid line away from the site boundary lines.
  18. To create other Grids at a specified distance from Grid 1, one approach would be to use the Pick Lines and Offset method shown in step 9. The other approach would be to use Copy tool. Let’s create Grid 2 to 10 using the Copy tool.
  19. Select the Grid 1.
  20. Copy Grids:

    • Go to Modify | Grids tab -> Modify Panel -> Copy
    • On the options bar, select Multiple as we want to create multiple copies of Grid 1.
    • On the options bar, select Constraint as we want to constraint the direction of copy downwards (similar to ORTHO ON feature in CAD). M2 Grid 14
    • Click anywhere on the Grid 1 to establish it as a base point for the copy.
    • Move your cursor downwards. A listening dimension in blue appears. Do not click anywhere yet.
    • Type the specified value between Grid 1 and Grid 2 as per Fig 1  (3.16m).
    • Note that a new Grid is created. Even though, we copied Grid 1, the name of the copied Grid is given automatically as “2” as per the sequence. In Revit, Grids cannot have duplicate names. Each Grid must have a unique name.
    • As multiple option was selected, the Copy tool is still active and more copies can be created by moving the cursor in the direction of copy and specifying the required distance. Using this method, create Grid 3 to 10 as per Fig 1.
    •  Click Esc twice to end the Copy tool.
  21. All horizontal and vertical Grid lines are added in the project.M2 Grid 15
  22. Add Grid symbols to both sides:

    • Note that by default, Grid symbols are appearing on the Grid lines only at one side. If you want to add the Grid symbols on both/either side, select one of the Grid lines.
    • Go to properties palette -> Edit Type -> Type properties dialog -> Plan View Symbols End 1/ End 2 parameters are displayed.
    • Click on Duplicate to duplicate the type and rename it.
      • TIP: Making a change in Type parameter will affect all Instances of the same type present in the entire project. If you do not want this change to affect all instances, then it is recommended that when you make changes to a type parameter, create a new type by duplicate the existing type and renaming it. This way, both the original and the new types are preserved and you can switch between both if necessary / choose which instances shall be affected by the change.
    • Check both parameters to make the grid symbols appear at both sides. (Checking only one of them would make them appear at one of the sides.)M2 Grid 3
    • Click OK after making the change.
    • The selected Grid will now have Grid symbols on both sides.
    • Select all other Grids that you would like to have the same change.
    • Go to Type Selector and change their type to the new type that you just created.M2 Grid 17
  23. Offset Grid Symbols: 

    • Note that on a scale of 1:100, some Grids such as Grid 7 & 8, Grid C & D have Grid symbols that are overlapping each other. For presentation purposes, this requires adjustments.
    • Select Grid 8. Note that there is a small Elbow drag control near the Grid symbol.  Click on this symbol and then drag the control to the desired location to move the bubble away from the grid line.M2 Grid 18.JPG
    •  Do the same for Grid 7 and 9 if required.M2 Grid 19
    • Click Esc to deselect the Grid lines.
  24. After completing all of the above steps, Go to File -> Save As this project as “TutorialGrids_Output_LearningRevitOnline.rvt”

TIPS:

  • TIP 1 : Custom Grid Symbol: If you want to change the size of the Grid symbol or wish to create a custom design of the Grid symbol, you will need to create a custom Grid Head Family. Learn more about it in this video tutorial by CADuniversity
  • TIP 2: Create Grids from CAD: If you are using a CAD drawing as a reference to draw your Grid lines, you can pick the lines in your CAD drawing to trace and create Revit Grids. Learn more about this method here.
  • TIP 3: Visibility of Grids: If you are unable to see the Grid lines in a particular view, check the visibility factors.
  • TIP 4: Appearance of Grid Line: To change the appearance of the center segment of the grid line, Select the grid line. In the Type Properties dialog, change the value for Center Segment to None or Custom and adjust the properties.

Define Levels

About Levels

Use the Level tool to define a vertical height or story within a building. Levels can be added or edited in a vertical view (either elevations or sections).

If you already have information about all the building story levels in your project, you may very well create them before you begin a project. If there are any changes later in the project, you can always come back and make these changes. In case, if you do not have information about all the levels, then it is necessary that you create at least one building story to begin your project. This makes it much easier to attach your walls and other building elements to the levels.

Tutorial Objective

In this tutorial, you will learn to,

Sample Problem:

Define Levels for the sample project as shown below:

  • Ground Level at Elevation Height +/- 00.00
  • Basement Level at Elevation Height -02.71m
  • First Floor Level at Elevation Height +03.05 m
  • Second Floor Level at Elevation Height +06.10m
  • Third Floor Level at Elevation Height +08.84 m

M2 Level Tutorial Sample

Fig 1. Levels for the sample tutorial project

Solution:

  1. Open the sample project file TutorialLevels_Input_LearningRevitOnline.rvt
  2. From the Project Browser, navigate to an Elevation view.
  3. As the sample file was created from an existing architectural template (as shown in previous chapter Create a project file) two levels are part of the template by default.M2 Levels
  4. Note that Level 1 is at 0.00m elevation height currently. In our sample project, we need the “Ground Level” also at 0.00m. So, in this case, it will be enough just to rename the Level 1 to Ground Level.
    • TIP: Naming Conventions: Level names typically will be reflected in the name of the plan views in your project browser where they are sorted alphabetically. Thus, while naming the levels, it is recommended to use naming conventions that allow an alphabetical sorting order to easily find the levels and corresponding plan views. For example, 00_Ground Level -> 01_First Floor Level -> -01_Basement Level. Some users like to add a prefix of the elevation height of the level to the level name in order to sort them correctly. For example, 00.00 Ground Level -> +03.00 First Floor Level -> -03.00 Basement Level. Of course, these naming conventions will still depend on your project specifications and standards.
    • For this tutorial, we are using the floor numbering as the prefix to the level name in order to sort them correctly in the project browser. Thus, the naming convention will be “00 Ground Level”, “01 First Floor Level”, “-01 Basement Level” etc.
  5. Rename the Level:

    • Click on the Level 1 line. The text of the level symbol will be highlighted as blue indicating that it is now editable.
    • Click on the text ‘Level 1’ and replace the text with “00 Ground Level”.
    • The Confirm Level rename dialog box will appear to confirm if the change in level name should be reflected in all corresponding views also? Say Yes to this message in order for all corresponding views to also have the same name as the level in project browser. M2 Levels 3
    • Notice that the Floor plan view named as Level 1 in the project browser is now named same as the level name.
  6. Now, Level 2 is at 4.00m by default. We would like to have the First Floor Level at Elevation Height +03.05 m. Thus, in this case, we will need to change the name as well as the elevation height of the Level 2.
  7. Repeat step 5 and  change the name of the Level 2 to “01 First Floor Level”.
  8. Change the Elevation Height of the Level:

    • Select the Level 2 line, the elevation height value is highlighted as blue indicating that it is now editable. Click on the value and replace it with 3.05m and press Enter. Note that the level line moves to the specified height. M2 Level 8
  9. Next, let’s create a new level for the Basement  Floor at Elevation Height -02.71m
  10. Create a new level:

    • Go to Architecture tab in the ribbon -> Datum panel -> Level
    • Click to enter start point of the level line. Drag your cursor towards the end of the line and then click to enter the end point of the level line. The elevation height of the level need not be accurate at this point.
      • TIP: Take your cursor towards the start point of the Ground Level line and without clicking hover your cursor downwards. Revit will indicate a reference extension line with a dimension that moves with your cursor. At this point, you do not have to be accurate about the dimension. Just click the start point for your new level line at a random point on that reference extension. Similarly, select the end point of the line by referring to the position of the endpoint for Ground level line. After you have placed the level, you can change the elevation height exactly at specified value.M2 Level 9
    • Level 3 will be created in the drawing.
    • Click Esc twice to end the level tool.
    • As shown in step 5 and 8, change the name of this level line to “-01 Basement Floor Level” and elevation of the level to “-2.71”. M2 Level 10
    • Note that a new floor plan view with this level name is added in the project browser.
  11. Using the process shown in step 10, you can create other required levels in the sample project files. Alternatively, you can also use Copy tool to create other levels as shown below.
  12. Copy a Level:

    • Select the “01 First Floor Level” line.
    • Go to Modify|Levels tab -> Select Copy from Modify panel
      • Alternatively, use “CO” as the keyboard for shortcut
    • Keep the ‘Multiple’ option checked in the options bar to make multiple copies of that selected level.
    • Click on any point on ’01 First Floor Level’ line and move your cursor upwards.
      • A temporary dimension (in blue) will appear. You can either choose to graphically select the point where a copy needs to be placed, or type in the exact distance from the base point where you want to the copy to be placed.
    • Type “3.05”value on your keyboard to specify the exact distance between the two level lines. Press Enter after typing the value. This level will become our Second Floor level for the sample project.M2 Level 11
    • As the multiple option is selected, the Copy tool is still active and you can make more copies by moving your cursor upwards and typing the exact copy distance/graphically clicking a point on the screen where you want the copy to be placed. Use this tool to create one more copy of the level that will become our Third floor level for the sample project.
    • Pres Esc twice to finish the Copy tool.
    • Change the name of the levels and elevation height (using the process as shown in step 5 and 8) as below:
      • Name: “02 Second Floor Level” Elevation Height value: “6.10”
      • Name: “03 Third Floor Level” Elevation Height value: “8.84”
  13. Note that the level symbols of Basement, ground and first floor are blue whereas, second and third floor level line symbols are indicated as black. The difference is that for the second and third floor level lines which were created by copy tool, do not automatically generate a plan view in the project browser. Thus, the level symbol indicated this effect by the colour black. If you would like to create a plan view for this level, then follow the procedure as shown below.
  14. Create a Floor Plan View:

    • Go to View tab -> Create panel -> Plan Views drop-down, and then click on Floor plan.
    • In the New Plan dialog box, Select one or more levels for which you want to create a plan view.
    • Click OK.
  15. Now, after creating floor plan views for all levels, note the project browser. All floor plans are sorted alphabetically in order due to the naming conventions we used in the step 4. M2 Levels 13
  16. After completing all of the above steps save this project file (Go to File -> Save) as “TutorialLevels_Output_LearningRevitOnline.rvt

Tips

  • TIP: Add ± symbol in text: If you want to add plus/minus symbol in the text/name of the level,
    • Open character map from your Windows (Windows Accessories -> System Tools -> Character Map) -> Copy the plus/minus symbol from here -> Go back to Revit
    • Select the level line. Click on the name of level name -> Paste this symbol in the text where required. Click Enter.M2 Levels 1
  • TIP: Offset level symbol: For presentation purposes, sometimes if the level heads are too close to each other, you may require to offset the Level symbol for clarity. Learn the steps how to Offset a Level Line from Its Bubble here.
