Hi, while experimenting with Alibre I needed a part library, I only had a spreadsheet with rectangular tube dimensions and part numbers and I’ve used Wizoscript (great tool, by the way) in order to auto populate the library. I’ve create a template part and used a script in order to modify and save it with a proper name. Of course the procedure can be adapted to other profiles, the only thing you need is a table with the dimensions. Since all the parts are generated from the same template I suppose this will allow a painless replacement in an assembly, if a size change is required. Attached are the files I’ve created, if that'd be useful.
