Hi,
I’ve been using 20c doing some modelling of a car. I would extract the door areas and then intrude the bottom of the car and the area left behind by the extracted doors. I was getting a lot of crashes when I tried to work with the extracted doors, specifically working with extrude. The area below the window of the door has two faces to allow for a curve in the door. When I look at the back of the extracted door this area is one face with an apparent depth to it . If I do cleanup on the door, the bottom face on the front side (half of this backside face) is removed. What I’ve started doing is to do the cleanup and then extrude region to give depth to the door and then replace the bottom face with another extrude but this is clumsy and not really accurate. Any hints on what I should be doing here would be appreciated.
Thanks
JRH
