![]() ![]() Also, if your model starts to become really complex ( lots of boolean), OpenSCAD becomes very slow and eventually unusable, even with the change described by the OP.ģ) If you need to model organic shapes neither freecad, fusion or OpenSCAD are unusable. Unless you don't know how to code, in which case it's unusable.Ģ) When you start to need chamfers and fillets, OpenSCAD simply doesn't work and Fusion is by far the superior solution. > Then I moved to Fusion and from that point I think that I’ve found a sweet spotġ) It depends on the kind of object you want to model: for simple, geometric shapes, OpenSCAD is by far the best choice. But for complex models it can’t really hold up to the more traditional parametric modeling software (yet) I too like OpenSCAD the best and often find myself more productive in it than other pieces of software, especially for simple models. Slicers these days are actually quite good at repairing geometry but even with a moderately complex part produced by boolean operations (in my case it was often one that required subtraction of cylinders across multiple pieces of an object) I found OpenSCAD’s output to produce some bizarre issues with geometry that even the slicer could not repair very well. But there is also still not a guarantee that the output of those boolean operations is actually a manifold object. It is not at all trivial in OpenSCAD.Īnother example of OpenSCAD’s limitations is the render time for parts produced by boolean operations which this change purportedly helps a lot with. This seemingly simple operation is rather trivial to do in FreeCAD and Fusion 360. ![]() One recent example is that I was designing a part for injection molding and I needed to add a draft angle to the part. Besides DXF files OpenSCAD can read and create 3D models in the STL and OFF file formats.I prefer the style of OpenSCAD but I’ve found that there are certain things that the software just is either really hard to achieve or incapable of doing entirely. ![]() In addition to 2D paths for extrusion it is also possible to read design parameters from DXF files. As data exchange format format for this 2D outlines Autocad DXF files are used. OpenSCAD provides two main modelling techniques: First there is constructive solid geometry (aka CSG) and second there is extrusion of 2D outlines. This gives you (the designer) full control over the modelling process and enables you to easily change any step in the modelling process or make designs that are defined by configurable parameters. Instead it is something like a 3D-compiler that reads in a script file that describes the object and renders the 3D model from this script file. Thus it might be the application you are looking for when you are planning to create 3D models of machine parts but pretty sure is not what you are looking for when you are more interested in creating computer-animated movies. Unlike most free software for creating 3D models (such as Blender) it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects. It is free software and available for Linux/UNIX, Windows and Mac OS X. OpenSCAD is a software for creating solid 3D CAD models. ![]()
