Trying to do a simple speaker ball…the cutout is already made and now I need to cutout from the inner side 4 polygons for the the nuts.
The add construction plane offers the possibility to align it flat to a selected surface…but I can’t select the surface which is inside…and since the outer parallel surface is angled, i can’t use that for drawing because it would move the polygon sketch not at the angle the construction plane is.
So how can I add a construction plane inside? Or is there a trick to move the sketch perpendicular to the plane?
Here’s how it looks like so far:
And as you can see…when I move the polygon, it is moved in the y-axis, but when extruding it follows perpendicular to the sketch plane:
