To combine curtain wall frames:
1. Click the tool and mode.
2. Select the curtain wall to edit.
3. Click the two frames to be combined. Frames must be collinear.
At a four-way frame intersection, it may be necessary to split a perpendicular frame to be able to join collinear frames.
4. One frame is created. The attributes of the first clicked frame apply to both frames once they are combined.
