![]() 2) Community libraries #īeing opensource means there's a great open-source community with many libraries available that can help make you more productive or open up new possibilities. Also OpenScad files are likely very robust and will continue for work for many years. You don't need an account there's no vendor lock-in or licensing issues. OpenSCAD is free, open-source software that you can download and run on your machine and do whatever you want with. The programmed nature of OpenScad gives it some unique advantages that have resulted in somewhat of a cult following for the software, but also some severe drawbacks. This is worlds apart from the click and drag nature of the other packages. Every part of the model comes from text you write, and the GUI part of the software is only there to inspect your model. The point of difference though for OpenScad, is that it's all programmed. Since OpenScad is cad software, it's amongst packages like fusion 360, Inventor, Freecad, Onshape and many more. In a nutshell, it's software for making 3d models that are dimensional and mechanical in nature, as opposed 3d graphics software like blender, which is better suited for artistic endeavours like assets for a game, as an example. OpenScad is a CAD or computer-aided-design package. And whether I think it's worth learning.What's it good for and not so good for,.Overview of OpenScad and where it fits in with other cad packages.Plenty more to explore in Wings which I prefer to use over Sculptris so far. I printed this object in bronze-filled PLA and polished it a bit - but not enough! In Wings I used the smooth operation a couple of times to produce a rounded shape. After a few experiments I made a solid edge version of Durer’s solid with OpenSCAD using my suite of polyhedral operators,Ĭonverted the ASCII STL output to binary with meshconverter and loaded into Wings. ![]() The Youtube videos (such as this one creating a Borromean knot - actually it’s a knot 7-1 (see my openscad knot generator ) by David Brinnen show the power of this program. It doesn’t import ascii STL either but it does support binary STL, and until OpenSCAD can export binary, I can convert with assimp. ![]() ![]() However I became more interested in using Wings 3D itself which has some very nice mesh operations. Discussion of the problem on the OpenSCAD forum led to the request to be able to control the GCAL mesh generation algorithm so that a better balanced mesh could be generated.ĭuring that discussion Neon22 suggested using Wings 3D to create a mesh more suitable for this kind of post-processing and indeed generously created a better mesh which behaved better in Sculptris. It may be something to do with the shape of the triangles which are very skinny. Sadly it seems that the kind of mesh generated by OpenSCAD is not able to behandled by Scultris - cracks appear as soon as the surface is manipulated. My first attempt was to modify the Oloid, (It turned out that assimp does a very poor conversion from STL to OBJ which causes this problem.) The OBJ exported from Sculptris is not watertight according to Repetier Host so I then use the online netfabb service (requires a Microsoft login). I found the online tool Meshconvert which uses the open source code assimp to converts from a wide range of formats to binary or ascii STL and OBJ. Sculptris cannot import STL files, only OBJ files, and OpenSCAD can’t export OBJ. Organic shapes with OpenScad and Wings 3Dįollowing up on the links on the Jumpstart page on Thingiverse as suggested by Laura Taalman, I installed Sculptris with the idea that I could use it to make mathematical shapes more organic by hand modelling geometric shapes created in OpenSCAD. ![]()
