And there are no functions to lower the level of detail of a scene, which could have saved many performance problems. Makes no sense to me why removing geometry makes the rendering 10x slower. I then did a simple difference operation with a cube, and it is so slow it is unworkable. I imported a worm screw from Jörg Janssen's gear library, which generates and renders just fine. The viewer also have many small issues where solid parts become transparent or color bleeds over from adjacent objects. Then there are some small OpenSCAD annoyances: doesn't start in full screen mode, doesn't remember how I want the customizer, and I must overshoot surfaces for the difference operation to work. I know that many people prefer functional languages for CAD, but I think OOP matches CAD better for how I break down the problem in my head. OpenSCAD's language is too limiting in what it can do. And is has a very bad text editor that doesn't even support find and replace. CADQuery has highlighted edges, but in a weird way, because you can also see part of edges that are not visible. It has an edge mode, but that outlines every single triangle, just a big mess. OpenSCADs biggest flaw in my view is that edges of objects are not highlighted, which makes them hard to see on screen. I played around with CADQuery, and it looks very similar to OpenSCAD. Looks like Python is the language of choice for many CADs, no way I can avoid learning it any longer. I hope it matures into a real product some day. Matt Keeter's work looks very interesting. Have you looked at Toolpath Language? tplang Other languages I can recall coming up include Haskell, Ocaml, and Rust.Īnd there are more Python projects than one can easily list Go: sdfx - A simple CAD package using signed distance functions to make STLs (golang -> stl). plasm net - this is a venerable tool used for modeling Roman architectureĪnd there are a number which use specific programming languages:.CadQuery - Python based language for building parametric 3D CAD models.pythonocc - 3D CAD/CAE/PLM development framework for the Python programming language - provides advanced 2d and 3d geometry modeling structures and algorithms: Bézier BSplines Extrude/revolve/sweep.There are a surprising number of tools in this space - one set of tools by Matt Keeter deserves especial mention: brlcad/include/brlcad/brep/surfacetree.Made a post which doesn't seem to be showing up - not sure why - here it is w/o the links:.brlcad/include/brlcad/bg/polygon_types.h.brlcad/include/brlcad/analyze/voxelize.h.brlcad/include/brlcad/analyze/polygonize.h.brlcad/include/brlcad/analyze/density.h.brlcad/include/brlcad/analyze/defines.h./usr/local/share/licenses/brlcad-7.32.6/LICENSE./usr/local/share/licenses/brlcad-7.32.6/catalog.mk.¦ ¦ ¦ ¦ pkg-plist: as obtained via: make generate-plist Expand this list (3818 items) Collapse this list.
