Hello Peter,New profiles could be added by using the User Section tools or by simply adding them to your AstorProfiles database. C:\ProgramData\Autodesk\Advance\Data - AstorProfiles2016.If you don't have microsoft access you can open the database through the management tolls by using the table editor.In the database, using the search filter, type in the section class name (EXT_AISC14_HSSRectangular) to locate the table. Once opened you can then create or copy existing sections to modify them.Best Regards,
