- dekhn 5y agoThe other (crucially) important part is that a change to a parameter only needs to cause recalculation of effected objects. With openscad, you have to re-run the entire program.
- phkahler 5y agoBut it doesnt have a constraint solver, so you'll be doing some math here and there.
- etskinner 5y agoParametric CAD means something more than just having parameters you can tweak. Like another comment said, having a constraint solver is key, and is much more complicated. Being able to say "this line must be tangent to this arc" or "this part must be concentric / mirrored / slotted to that part" is central to parametric modeling, and is not the same thing as merely having variables
