MSTech-AiCAD
FreeCAD-based AI-assisted parametric CAD with a SolidWorks-style workflow and a built-in Claude design assistant.
What it does and how it connects
MSTech Ai-CAD is a professional 3D parametric modeler built on FreeCAD. It pairs a SolidWorks-style workflow with a built-in AI design assistant powered by Claude: ask for a part in plain language and the assistant asks clarifying questions, then models it feature by feature while the user watches.
The interface uses a tabbed command ribbon with large primary commands, a heads-up view toolbar, a confirmation corner in the 3D view, and task panels beside the model tree, with SolidWorks-style mouse controls and light and dark themes in Turkish and English. It keeps full FreeCAD power, Part Design, Sketcher, Assembly, TechDraw, BIM, Mesh, and more, and files stay fully compatible with FreeCAD .FCStd. Installers ship for Windows, Linux, and macOS, and the builds are not yet code-signed, as the README states.

- solidifai
A desktop build123d studio with a live viewport, rather than a FreeCAD-based modeler with a SolidWorks-style ribbon.

Recurring errors it addresses
Error Index entries this tool is built to reduce or work around.
- A FreeCAD user reports fillet/bevel as big weaknesses of FreeCAD and shows a fillet that breaks in FreeCAD and in the FreeCAD-Nxt add-on meant to fix it.Error Index
- a PartDesign Pocket whose sketch shares coincident edges with existing walls fails OpenCascade's boolean at the default 1e-7 tolerance and the whole body disappears from view; the workaround is hand-offsetting the sketch 0.01 mm inward.Error Index
- A pocket operation sometimes drops its final depth pass, producing 3 Z layers instead of 4.Error Index
- a script that deletes TechDraw pages to rebuild them races the background view recompute, and FreeCAD aborts with no message and loses unsaved work.Error Index
