After spending 5 minutes with Replicad, I canceled my subscription to Fusion360. Thank you @sgenoud!

Context: I have design and shipped physical products (injection mold plastic), but have found the parametric support in Fusion to be almost unusable, as it's tied to the order of operations. For a recent laser cutting project, I did the CAD in HTML—using JS to lay out SVG elements based on input fields for all the parameters.

Given the above, Replicad is a 100% fit for my philosophy and needs:

• Code-driven, so I can completely control how things are parameterized (and use arbitrary expressions)

• Text-based, so I can work in a Git repo

• Open source & web based, so I don't worry that I'll lose the ability to view or edit old files in the future

• Well-funded core (OpenCascade), so I have reasonable hope that it will continue to receive updates

• Human-friendly documentation, so I can find what I need quickly

Really nice work!




Was FreeCAD unsuitable in some way? It's been around forever, also based on OpenCascade.


afaik, FreeCAD is not code-driven or text-based. In the few minutes I played with it, it seems like a massive app which is sluggish on fast computers, and stores its data in an opaque binary format. So it's not really in the same category.


It has an OpenSCAD workbench if you're familiar with that, and it has Python embedded and it's used throughout:
