Composite Design Analysis Creates New Beam Family

[fbratton]

Does anyone know why the composite design extension creates a new beam family when a design is accepted?  In laying out trial framing we used the standard Revit family, but after using this extension the newly designed beams are in new family named "W-I-sections (with constant flange thickness)-Beam".  Any idea why or how to change it?

Starting from integration of this plug-in with Revit Eextensions in 2011 release it is using Content Generator extension to generate appropriate family then design is accepted. It results in generation of family “W-I-sections (with constant flange thickness)-Beam” different than standard Revit family “W-Wide Flange”.

It is done this way to avoid problems with availability of Revit content depending on parameters of its installation.

The easiest way to replace it by standard family is to select single beam with such section, use “Select All Instances” and then replace in properties of selected beams the family assigned by extension by standard family.
