I thought this would have been easy, but as normal I am struggling to figure out how to do the following.
I have a 1000 x 1000 x 60mm plate that needs to be machined on the underneath, the machined area is not parallel to the edge of the plate.
So I thought I could sketch the profile of the area to machine then add a plane to the profile and then cut up to plane
However when I select the sketches for the profile I getting error messages about invalid selection.
Can this machining be done in one go or do I need to do it in two.
Can someone please point me in the right direction.
I have added the part with the sketched profile and a sketch of the finished part.
