Recently I came across an issue, when I activate Erase not displayed command Creo crashes. I am not aware of the reason why?. Somebody could throw some light on this and help me?
If the difference of 'recently' is that you have recently started working with models that came from a later build of Creo 2, then you may be experiencing the problem documented in https://support.ptc.com/appserver/cs/view/solution.jsp?n=CS246507
If this is the case, you will find your issue is resolved by updating to Creo 2 M240.
Sometimes the same thing happened to me. I notice that all start when I received a ¨fatal error¨ message. After that point, each time I used erase not displayed, Creo crashes automatically.
I am getting the same issue on assemblies that use several family tabled sub assemblies. It is really anoying. I am on Creo 3.0 Essentials. I cam from a company that used the same type of subs and assemblies and there we did not have this issue but we were on PDMLink.
