Designmatix Text-to-CAD turns natural language into engineering-ready STEP files. Describe what you need — bolts, brackets, sheet metal parts — and get a real, manufacturable 3D model in seconds. No CAD experience required.
Type what you need in plain English. Geometry, dimensions, materials. Try flanged cylinder, 50mm tall or L-bracket, 3mm steel.
Designmatix converts your description into Python CAD code, then builds the geometry using OpenCascade — the same engine that powers FreeCAD. Takes 5 to 15 seconds.
Get a real STEP file (ISO 10303) plus STL, ready to open in SolidWorks, Fusion 360, FreeCAD, or your slicer. Inspect the generated Python code if you want to tweak it further.
Generate hex bolts, socket caps, threaded studs, and washers to standard or custom dimensions. Useful for assembly mockups or 3D printing fixtures.
L-brackets, mounting plates, gussets, and shelf supports — with mounting holes, fillets, and proper flanges. Specify thickness and hole pattern in the prompt.
Bent enclosures, flanges, and panels with proper bend radii and material thickness. Tracks aluminum, mild steel, stainless, and 6 other common materials.
Flanges, hubs, pulleys, gears, and any rotational or extruded part. The model writes real CadQuery Python — you can read and modify it if you know the language.
Output is ISO 10303 STEP — the format every CAD package reads. Open in SolidWorks, Fusion, FreeCAD, NX, Catia. Modify the geometry, add to assemblies, send to manufacturing. It's not a screenshot or a mesh; it's parametric solid geometry.
Every generation produces real CadQuery Python. If the result isn't quite right, inspect the code, learn what went wrong, edit and re-run. Designmatix is a starting point, not a black box.
Designmatix is free to use — you provide your own Anthropic API key (around $5 of credits handles dozens of generations). Your key never leaves your browser session. We don't store it, log it, or use it ourselves.
