START WITH C # PROGRAMMING FOR REVIT ARCHITECTURE: I tried to do an exercise that involves the creation of rectangular columns. For this reason we created the class (PICTURE CREAZIONE FAMILYLABSCS.JPG):
C:\TEST\pil\FamilyLabsCS\FamilyLabsCS\FamilyCreateColumnRectangle.cs
I then created the file addin (see picture 0 ADDIN.JPG).
Then I open Revit Arch 2013 and when I click on "PILASTRO" me 'a mistake or misses the
“FamilyLabsCS.RvtCmd_FamilyCreateColumnRectangle”
contained in FullClassName (PICTURE ERROR.JPG). Why is that? Thanks for your cooperation.
