Start a new project. Draw curtain walls in the new project, add grid
lines, apply mullions(all types if you need them, i.e., corner,
rectangular, quad, etc) to the grids. Then, copy and paste the curtain
wall and mullions to your project.

> I seem to have "purged" the mullion styles from my project. Now I am unable to add mullion styles to a curtainwall I just added, and receive the message that no curtainwall mullion families are loaded. I cannot find any curtainwall mullion styles to load. How do I get these back into my project?
