It is maybe worth noting that with basic solids like block or sphere, they are parametric. You can go back and just change the numbers to re-size. Also, any extrude function can be edited to change the distance with just a number. But the thing that I have found interesting over the last several versions is that in analyze mode you can edit XYZ locations of endpoints of lines and center points of arcs, as well as radius or diameter and sweep angle of arc and the vector angle of a line, and the the 3D length of either. Changing 3D length and sweep or vector doesn't give you a choice of which end is going to change, so that's not very good control. But it does allow you to just change numbers to modify the chained geometry for a solid function.

Yes. That's exactly what's happening. That's why containment is clean. I'll have to remember that next time avoidance is giving me messy boundary toolpath. Sometimes making the avoidance stock-to-leave less than the cut stock-to-leave by a few tenths will help smooth the edge of the toolpath. But I like the containment. The other day I used depth limits to get rid of some jerky stuff at the end of a similar toolpath.

It's definitely a size issue. I did it as revolved surface, revolved solid, surface from solid. That thing is .1mm! I scaled the wire x100, and then the revolved surface is smooth. Of course scaling adds another tolerance/rounding issue. When scaled back down, it becomes triangulated again, and not a nice curve. You could go into your config settings and add a couple decimal places to some of the math for CAD. 3 curve surface.mcam
