To modify an instance property of an architectural column, you change the value of the corresponding parameter, as described under Modifying Instance Properties.
Common instance properties for architectural columns are described below.
| Name | Description |
|---|---|
| Constraints | |
| Base Level | Specifies the level on which the base of the column rests. The default is Level 1. |
| Base Offset | Specifies distance from the base level. The default is 0. |
| Top Level | Specifies the level that the top of the column reaches. The default is 1. |
| Top Offset | Specifies distance from the top level. The default is 0. |
| Moves With Grids | Columns move when grid lines are moved. |
| Room Bounding | Determines whether the column is room-bounding. See Room Boundaries. |
| Top is Attached | Read-only parameter specifying that the top of the column is attached to a structural floor or roof. See Attaching Columns. |
| Attachment Justification At Top | When the column is attached to a surface, sets the top justification for the condition. Choices are: Minimum Intersection, Intersect Column Midline, Maximum Intersection. |
| Offset From Attachment At Top | When the column is attached to a surface, specifies an offset value for cut target/column conditions. |
| Base is Attached | Read-only parameter specifying that the base of the column is attached to a surface. See Attaching Columns. |
| Attachment Justification At Base | When the column is attached to a surface, sets the base justification for the condition. Choices are: Minimum Intersection, Intersect Column Midline, Maximum Intersection. |
| Offset From Attachment At Base | When the column is attached to a surface, specifies an offset value for cut target/column conditions. |
| Identity Data | |
| Comments | Specific comments for the column instance. |
| Mark | Applies a tag to any column for reference purposes. This value must be unique for each column in a project. Revit warns you if the number is already used but allows you to continue using it. (You can see the warning using the Review Warnings tool. See Reviewing Warning Messages.) |
| Phasing | |
| Phase Created | The phase when the column was created. |
| Phase Demolished | The phase when the column was demolished. |
