Then you are not actually getting a model with a constraint system at all. Which is the point of the thing I'm replying to.
CAD constraints are more powerful and flexible than OpenSCAD, and the power comes from analysis of what the part is actually for, not merely what it looks like.
You can't even compel OpenSCAD to keep a line and an arc tangent. If hull() can't do it, you're making it up yourself with maths.
