Hello. I design thermoformed packaging, mainly clamshells, and I am not real familiar with Simulation. I have been having a lot of trouble lately with clamshells not being balanced when hung on a peg. I was wondering, would it be possible to test a design and see if it balances properly using Simulation, before I actually get a physical prototype made? I have SolidWorks Pro so I don't have the full Simulation package. Thanks.
