OpenSCAD is a neat tool, but it has a few huge drawbacks for real world use: - a weird domain specific language that only adds a bit of syntactic sugar and is a pain to learn. They would have been *way* better off using Python and extending it. - no filet / chamfer tool. No CAD program can be taken seriously unless it has those. - the CAD core is (IIRC) CGAL, which only works with polygonal models and is god-awful slow as soon as the model gets complex. For example, Minkowski sums are basically unusable on any real-world model. What is really neat about OpenSCAD is the notion that a 3D object is basically code. This brings in for free a ton of very nice things: - version control - collaborative editing - parametric modeling - object optimization
