It would be very helpful, if there was an option to check importet lines/curves like IGES, to see if there are two ore more of them. Sometimes the interface of some CAD-systems exports more then one curves and in Moldflow you can't see this.
The Problem is, when you edit the properties to channels and meshed it, you have overlapped beams.
It spend many time, to check this and find the problematic areas.
