To Define the Mullions of a Curtain Wall Using a Profile

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.

Note: The insertion point of the profile is aligned with the centroid of the mullion.

Infill alignments with default and profile-based mullions

1. Create the profile to use for the mullion.
2. Click Manage tab Style & Display panel Style Manager .
3. Expand Architectural Objects, and expand Curtain Wall Styles.
4. Select a curtain wall style.
5. Click the Design Rules tab.
6. In the left pane, select Mullions under Element Definitions.
7. Click New Mullion.
8. Enter a descriptive name for the mullion.
9. Specify a width and depth for the mullion.

   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.

10. Select Use Profile.
    Note: The Profile options are available only if you have profiles in the current drawing.
11. Select a profile from the list.

    By default, the profile is inserted using the same width and depth with which it was created.

12. 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.
13. To mirror the profile, select X or Y for Mirror In.
14. To rotate the profile, specify a rotation angle for Rotation.
15. Specify any offsets.
16. Click OK.

After you create a mullion definition, you can assign it to any mullion in a curtain wall.
