Curtain WaIl Segments - Alternate Workflow

When you want to add or remove mullions along a gridline or grid line segment.

You typically would use the Mullion tool under the Architecture Tab but sometimes it does not let you place a mullion.

Here's the part that (to me) wasn't obvious.

When that tool isn't working for you.
Instead, with no command active, select the gridline that you want to add the mullion to.
Then, click the Add/Remove Segments button that is available when a gridline is selected.

You should be able to click and add (or remove if desired) mullions to the desired segment.

Storefront Repeating Mullion Spacing

Place storefront with equal mullions. Select desired storefront wall. Before placing, edit type, set vertical (horizontal too if needed) mullion spacing to desired distance (fixed, minimum or maximum), place storefront wall.

To edit/change mullion layout, select the Curtain Wall that you just placed, Edit Type from the Properties dialog. Change vertical mullion spacing to None.

Revit offers to automatically delete the grids and mullions in a warning popup after you click OK from the Edit Type properties box. Selecting "Delete Gridline" deletes the grid and associated mullion, selecting "OK" leaves them in place but makes them editable. Edit away!


Note: Don't forget Edit type effects all instances of that Curtain Wall in the project, not just the one that you originally selected.
