Use this procedure to create a mullion element definition from a profile. If you do not want a straight edge to your mullions, you can use a profile to define mullions with curves, jags, or any other shape.
You can also use an edit in-place routine to create a mullion from a profile.
Because door/window assemblies can contain multiple nested grids with different mullions, it is helpful to use a naming convention for grid mullions that indicates the grid location or purpose within the door/window assembly. For example, L3-FL1- Window Mullion identifies a mullion for a window in a third-level grid on Floor 1.
- Create the profile to use for the mullion.
- Click
. 
- Expand Architectural Objects Door/Window Assembly Styles. Note: Alternatively, select a door/window assembly in the drawing, and click
. - Select a door/window assembly style.
- Click the Design Rules tab.
- In the left pane, select Mullions under Element Definitions.
- Select a mullion definition or click
to create a new one. - Enter a descriptive name for the mullion definition.
- Specify a width and depth for the mullion definition.
These dimensions are used to calculate the center point of the mullion for aligning the profile, and also to specify a boundary for the adjacent infill.
- Select Use Profile. Note: The Profile options are available only when you have profiles in the current drawing.
- Select a profile from the list.
By default, the profile is inserted using the same width and depth with which it was created.
- To adjust the size of the profile to fit within the width or depth dimension of the mullion, select Auto-Adjust Profile Width or Depth.
- To mirror the profile along the X or Y axis, select X or Y for Mirror In.
- To rotate the profile, specify a rotation angle.
- Specify any offsets.
- Click OK.
After you create a mullion definition, you can assign it to any mullion in a door/window assembly.
