Hello members, it seems I was expecting SWx to do too many adjustments when using the draft angle feature.

I have the cup at upper left, and was hoping that if I applied a draft angle on faces A and B, SWx would take care of adjusting faces C, D, E and F to remain approximately as they are in the cup, but shifted over to accommodate the taper of its cylindrical wall.

Creating a draft angle feature by choosing only A and B led to Cup 2 tapering into disappearance; next

Creating a draft angle feature by choosing A, B, C and D led to Cup 3 with faces C and D appearing as phantom surfaces, and the bottom section becoming a grouping of disconnected surfaces.

While choosing A through F won't complete with E+F being perpendicular.

I find in online advice that draft is applied to solids, and it works out ... but if using solids means creating a cup with no interior as a solid mass, and next creating its interior by subtracting another solid, that would separate my work on the exterior surface from my work on the cavity, more tedious and less natural for refining a form, but doable if it's the route that works.

Do you have a way of applying draft angle that ought to work here that preserves the ability to develop the cross-section as a whole, do a revolved base, and at some point taper the walls?

Thanks
