About Sheetmetal Profiles
A sheetmetal profile is cut from a flat sheetmetal part and folded into a profile with a constant cross section.
A flat instance of the folded sheetmetal profile is created automatically. A family table with one instance (part_name_fl) is created for an assembled sheetmetal profile.
When creating joints, a sheetmetal profile requires different shapes for mitered profile ends.
Standard sizes are not shown in the Element Definition dialog box. Choose the required size from the tables or enter individual section dimensions.
 
* Assemble new instances of sheetmetal profiles as you would regular profiles.
