Wall Editing Fatal Error

[kthurman]

Hello,

I have having trouble with the wall panel editor giving me a fatal error when I am trying to edit the dimensions of my regions. It is a compound wall with different CMU materials at various elevations for the finish course. Every time I attempt to edit the vertical dimensions of the various courses the program crashes with a Fatal Error.

I recorded a screen cast of the error and attached it. I am in Revit 2017 but have had this issue in the past under previous versions.

Any suggestions?

Thanks,

KT
