Hey guys. I am very very new to sketchup coming from solidworks. I am struggling on a next level trying to model tents in this software but the job requires it. In any case i have used the curviloft plugin to make the tent body but I need to be able to cut a hole in it for the door. I have attached a picture of what I am trying to do. I've tried using the push pull and joining the edges and deleting away the unnecessary parts as well as use the subtract tool. It would seem like the problem lies in the curviloft feature is a face and a solid so I cant cut it. If anyone can help out with this it would be much appreacted.
