Which software is more useful and handy for sheel metal design?
Accepted answer
CATIA has a good sheetmetal workbench, which is integrated well with other applications such as solid and surface modeling, drafting, analysis, etc. But many other CAD systems also have good sheetmetal capabilities, such as the ones you have listed in your skill set (SolidWorks, Pro-E, AutoCAD, etc)
As a beginner, you can't go wrong learning any of them.
