I’ve created a simple sketch for a wall mounted case. See attached lunos.shapr (1.0 MB)
I want to extrude the bottom exempt the large oval hole and mounting holes to form a 3mm bottom. Then I want to extract the offset wall to to full 25mm
I miserably fail. I can either extrude the wall. The I can’t hilight the inner parts of the sketch anymore. Or I can extrude the bottom. I then can’t select or extrude the wall. Sketching on top of the bottom extrusion by trying to create a offset also fails, it always adds the whole bottom part to the sketch.
