I'm trying to model a spring with closed flat ends by sweeping a profile along a 3D sketch of the springs' path, then cutting the top and bottom flat with an extruded cut. Unfortunately, I'm experiencing an issue where the swept feature disappears and an odd display artifact of the cut profile is all that remains. I've also tried extruded cuts from the top and bottom of the part, with similar results.
Has anyone else seen this bug? Is there a known workaround?
I'm using SW Premium 2016 SP 2.0
