A full-featured 2D + 3D CAD application built in Rust with GPU-accelerated rendering. Native DWG & DXF read and write, paper space, ACIS solids, dimensions, layouts. An open source community project by Hakan Seven, recognized and promoted by the OpenAEC Foundation.



FreeCAD has become pretty good lately. If you have tested it before v1.1 (March 2026) you should certainly give it a go again.
If you’re fine with programming your CAD instead of visually composing it, OpenSCAD is fine as well.
I do like openscad but I must be using it wrong because it slows to a crawl when trying to array my models
Maybe you can reduce the $fn parameter while you arrange your models and increase it once you’re done? That’s the most common thing I encountered.
There are some config flags you can set which might improve render times, maybe play around a little.
All in all it will take a long time to create meshes because most of the compute is done on CPU. For me it’s very fast once it’s done rendering, so I try not to render too often.
