Revit 2022 Curtain Wall Mullions can’t be Transferred between Projects


There are many things that can be transferred between projects, but unfortunately, Revit Mullion definitions can not be transferred.

Mullions are created using system family definitions. They have a profile that is nested that determines the shape of the mullion.

They also have a parameter that determines the size of the types of mullions that are created.

Some of the other mullions – like the Quad Corner Mullion – do not have a profile linked in, and only the size is available for defining the size of the type.

It is good practice to set up a project file containing some walls for use in other projects. Usually, one would make the statement that after a purge, one may just transfer all the wall types from the “Family” project into the other. Now with curtain walls, one would also have to copy an instance of a curtain wall into the other. Copying the wall into another project also transfers the mullion definitions that the curtain wall contains. It might therefore be a good idea to create a curtain wall type that hosts all the various mullions you need to exist in another project. Copying this curtain wall into another project will then also copy the mullion definitions into that project.
