New SMS user here... just wondering, does it matter if all the coverages are on the same plane? I have noticed that when you switch to the 3D mode, depending on what coverages are visible when you create them, they appear in different planes. I am just wondering if this is what is causing my model to crash. I have run a successful model, but I never actually noticed this scenario. Now, this model won't run, and I am curious as to if this is the reason? Any advise or knowledge pertaining to this situation would be great! I have attached 2 separate pictures showing both scenarios encase my explanation was poor. Thanks!
