> I think OpenSCAD is currently the best and most feature complete choice As much as I love OpenSCAD, I would strongly disagree with your conclusion. All the OpenSCAD language can do is boolean operations and moreover, the engine can only implement those on polygonal (triangle actually) meshes. That's a very far cry from what a modern commercial CAD engine can do. For example, the following things are very, very hard to do, or even specify using OpenScad: - Smooth surfaces, especially spline-based - Fillets / Chamfers between two arbitrary surfaces - Trimming surfaces - Querying partly built models and using the outcome in the subsequent construction (e.g. find the shortest segment between two smooth surfaces, building a cylinder around it and filleting it with the two surfaces, this is an effing nightmare to do within the confines of OpenSCAD) - Last but not least: there is no native constraint solver in OpenSCAD, neither in the language nor in the engine (unlike - say - SolveSpace) I might have misunderstood what you're looking to do, but, yeah, digging deeper feels very much like the right thing to do.
