I'm in the process if building a CAD app that I feel is a pleasure to use. For me, that means writing it in Rust. For now, that project is private until I feel comfortable sharing, but I'm working on a binding library in parallel. https://github.com/occt-rs/occt-rs I've only spent a day on _this_ re
This is pure C wrapper from cpp project in order to get DLL for FreeBasic Porgramming Language: Look for it into github "FB_OPENCASCADE", https://github.com/jepalza/FB_OPENCASCADE By the moment, only simple viewer controlled by FreeBasic and demo for Booleans. I't very difficult for me to try to get

Hi all, I wanted to share some Haskell OCCT bindings that I've been working on. They're hosted here, on Github . There are API docs over on Hackage .

I took example project from opencascade example folder, added a lot of stuff: imgui support for UI, opening files and showing them in list, processing selection of nodes in scene, many other tweaks and things. Wanted to add more things, like saving projections to dxf files, but project is not that p
Hi all, I just got the news about the first public release of NaroCAD. I'm although a bit confused with the different CAD projects currently in development.

Istvan csanady has made an unbelievable smooth, good looking CAD modeller , running on an iPad Pro... What I find impressive is the solid modeling that is topology driven ( grab a face, move it, select and edge, fillet it, draw over a face, subtract from it ) Really gives a great feeling of optimism
