> 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.

(my) fncad doesn't have the querying, but it does have smooth csg! https://fncad.github.io/

using BOSL2 alleviates most issues I've run into with OpenScad for chamfers and the like, but it is an extra set of functions you need to remember sadly

It's also extremely slow: it implements chamfers and fillets using morpho, and if you have a large number of fillets, the morpho algorithms (minkowski / hull) are very much non linear in time on polygonal meshes, which leads to compute time explosion if you want a visually smooth result.

		you can get around this somewhat by having less visually smooth previews when editing and higher quality when you want an stl `$fn = $preview ? 32 : 256;`
