| Well the readme states the following:
|
| _Solvespace on the other hand gets the workflow part right,
| but falls short by not importing STEP and the geometry kernel
| not supporting chamfers and fillets._
|
| So I assume that's where that comes from.

| FreeCAD is the worst. Thanks for building this!

| For years I agreed with you - I tried FreeCAD multiple times,
| different versions, always sucked.
|
| Then I watched this video [0] and discovered that v1.1 is
| different - and that it's good enough for solid reliable hobby
| usage. It's still a touch frustrating in a few areas (text, for
| example) but I've now switched over to it completely.

| To echo others' comments: FreeCAD has improved significantly

| Awesome because you can build a model, expose the parameters,
