I have shelled box, and I used a shelled cube to "cut" a lid or door into it. Something like this :
I want to add a lid along the border of the cut. That stays inside the body and allows the lid to sit agains it. I found no way to add an sketch into the curved surface.. I can add an sketch to the flat surface of the cut.. but if I would cut the doot using a cylinder or another "curvy box" like the main one.. them I'd be unable to find a flat surface where lay my thing..
How can I do that? A lid of 2 mm deep, that enters 2mm into the hole, along the cutting path. Any idea ?
EDIT:
As mentioned, I managed to do it on ONE surface, just because is flat and hand drawing most of the thing.. here is how it look like, not totally bad, but I guess there is a way to just go along the border of the cut ..
I also managed to draw a profile and use "SWEEP" to have the lip around ONE edge, but no along them four and the corners get rather tricky ..
