After building a new valve, I can't get it to attach at the attacher arrow nor in Revit. The new valve was a copy of another with the only thing different being the dimensions and connectors.
After that, I took a another valve and just dumped the new dimensions into it leaving the same fields but deleting one that wasn't needed. Nothing.
Same as above but left the deleted field. Nothing.
The original works, the copy doesn't.
See attached. The file with the underscore is the new one.
Signed, Deeply frustrated.
