I want to import a sketch section which was save as IGES format to Pro-E, and use it to build a 3D model by extruding it. The problem is when I try to import the skecth using Date from file from the sketch menu, a dialogue box shows and says you are attempting to import too many entities into Sketcher and the Intent Manager is turned off. I cannot exit the sketch because it is unresolved. I tried to go through every options availabe in the Intent Manager and still cannot get the sketch resolved. More accurately, I have no clue where the problem is with the imported sketch, e.g., discontinuity of the sketch, points shared by more entities... Anyone has good idea to clean the sketch please?
