I'm new to programming. I tried searching for this in SolidWorks specific terms and more broad VBA terms, but I couldn't find an answer.

I understand swApp is arbitrary and could be anything. This also goes for swModel, swAssy, ect...

I've noticed Excel macros are the same way. excelApp = Application.Excel

What are the reasons behind setting swApp = Application.SldWorks and using swApp throughout a macro instead of just typing Application.SldWorks  when necessary?

Thanks for the information.
