Hi,
I subtracted a revolved object from another object, splitting it in half. Now, I’d like to create an offset (inset) of the inner face of said cut object, but it doesn’t not seem to be possible. Also when I try to draw sketch lines on the surface, they behave erratically. There is a line going from the edge of the face to its middle (where the revolve was on the object which was subtracted) and this, I assume, is the issue; revolved faces perpendicular to the axis seem to have unwanted properties, as they have a “seam” from the revolve. Is there an easy way to get around this?
