About Columns

There are two types of columns in Revit:

1. Structural Columns
2. Architectural Columns

As their name suggests, use the structural columns to add load-bearing vertical elements to the model and use architectural columns to add decorative vertical elements. Structural elements such as beams, braces, and isolated foundations join to structural columns; they do not join to architectural columns.

Tutorial Objective:

Before moving onto this tutorial, please make sure that you already know how to load a family into the project and create new type for a family (example as shown in the tutorial for doors).

In this tutorial, you will learn,

• To place a structural column
• To place an architectural column

Sample Problem:

Add an architectural column surrounding the structural column on Grid B-4 in the Ground Floor layout as shown below.

• Height of both columns: Ground Level to First floor level
• Structural Column: UC-Universal Column Type 254x254x73UC
• Architectural Column: Architectural-Column-Rectangular type 300 x 300

Sample Files required for this tutorial:

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

1. “TutorialColumns_Input_LearningRevitOnline.rvt”
2. Column Family files: “UC-Universal Column.rfa” and “Architectural-Column-Rectangular.rfa”

Solution:

1. Open tutorial file ‘TutorialColumns_Input_LearningRevitOnline.rvt’ in Revit. This project file already contains levels, grids and walls on ground floor level.
2. Navigate to the floor plan of  “00 Ground Level”.
3. Load the families “UC-Universal Column.rfa” and “Architectural-Column-Rectangular.rfa” into the project.
   • Click Insert tab -> Load from Library panel -> Load Family -> Navigate to the folder where above families are located on your computer -> Select them -> Open.

4. To place a structural column:

   • Go to Structure tab -> Structure panel -> Column
     • Alternatively, use “CL” as the keyboard shortcut .
   • From the Modify|Place Structural Column tab , select vertical column.
   • From the type selector, select the type 254x254x73UC of the UC-Universal Column family you loaded in step 3.
   • On the options bar, select the Height and constraint it to First Floor level.
   • In the drawing area, notice that column’s center automatically tries to snap at the grid intersections. Click at the grid intersection B-4 to place the column.
   • Click Esc twice to end the Column tool.
5. Now, we would like to place a rectangular architectural column that surrounds the structural column that we placed in step 4.

6. To place an architectural column:

   • Go to Architecture tab -> Build panel -> Column drop-down -> Column: Architectural
   • From the type selector,select the type 300 x 300 of the Architectural-Column-Rectangular family you loaded in step 3.
     • If you do not have this type, create a new type by duplicating the existing one and changing the width and height value of the type parameters to 300mm.
   • On the options bar, select the Height and constraint it to First Floor level.
   • On the options bar, select the ‘Room bounding’ option. This will ensure that the boundary of the column is part of the boundary of the room along with other room bounding elements when you create a room.
     • Learn more about Room bounding elements here.
   • In the drawing area, notice that column’s center automatically tries to snap at the grid intersections. Click at the grid intersection B-4 to place the column.
   • Click Esc twice to end the Column tool.
7. Now, we have a structural column that is surrounded by an architectural column.
8. Go to a 3D view to see these columns in a 3D.
9. After completing all the steps above, Save As your project as “TutorialColumns_Output_LearningRevitOnline.rvt”.
