Text to FreeCAD, with the feature tree intact
Most AI CAD tools hand you a mesh or a frozen solid. Open their STEP file in FreeCAD and you get one lump with no history nothing to click, nothing to edit. ChaordCAD builds the part the way you would: sketch, pad, pocket, each step recorded on a real .FCStd tree you can open and keep working on in stock FreeCAD.
What you get from most text-to-CAD tools
A mesh
STL output. Triangles, not geometry. There is no dimension to change and no feature to remove only a surface.
A frozen solid
STEP output opens in FreeCAD as a single Part object. The geometry is real, but the steps that built it are gone you can’t grab a pocket and change its depth.
A slider, not a tree
Some tools expose a few parameters as sliders. Useful for small tweaks, but it’s a configurator over a fixed model, not a real, inspectable feature tree.
What ChaordCAD gives you instead
Every generation produces an actual FreeCAD document. Open it and the model tree looks like something you built by hand: a sketch, a pad, maybe a pocket and a fillet after it each one a separate, editable feature.
Change a dimension, recompute
Double-click the sketch, change a constraint, hit recompute. The pad, the pocket, and everything downstream update the way they would if you’d modeled it yourself.
Delete or reorder a feature
Don’t want that chamfer? Delete it from the tree. The rest of the model isn’t held together by a single frozen solid, so removing a step doesn’t break everything after it.
Keep working in FreeCAD
No plugin, no export round-trip, no reconstruction step. The .FCStd opens directly in the FreeCAD you already have installed.
Export when you’re done
Need it elsewhere? Export STEP for other CAD tools or STL for printing, straight from the same model.
Where this doesn’t help
ChaordCAD is built for parametric mechanical parts brackets, enclosures, mounts, simple gears. It won’t give you a full multi-body assembly, organic surfacing, or production-ready GD&T. For those, you still want a full CAD environment and a real engineer. This is a starting point you can keep editing, not a replacement for one.
