It has helped me solve my problem of finding out what will happen when I try to make something without knowing how it works, or even if there are any problems with the product that could be causing issues later down the line (like breaking). The interface can sometimes seem confusing at first but once you get used to using it everything becomes second nature for solving your own engineering designs in CAD programs like Solidworks. There really isn't anything bad about this program so far! What else? Nothing comes to mind right now as well. If you're looking into making custom parts, then this tool should definitely help you do just that.
