What is Text to CAD?
Text to CAD is the process of turning a written description of a physical part into a 3D CAD model. Instead of opening traditional CAD software and drawing sketches, extrudes, and holes by hand, you describe the part in plain English, including dimensions, and an AI-assisted tool generates a starting model you can refine and export.
How text to CAD works
A text to CAD system reads your prompt, maps it to geometry (boxes, cylinders, holes, wall thickness, and so on), then builds a solid model with a CAD engine. With FreeTextToCAD, that engine runs in your browser: you get a 3D preview, optional dimension sliders, and STL/OBJ export for printing.
Text to CAD vs traditional CAD
Traditional tools like Fusion 360 or SolidWorks give precise, feature-by- feature control and shine on assemblies, drawings, and manufacturing documentation. Text to CAD is faster when you need a small printable bracket, hook, washer, or enclosure and you already know the sizes.

What makes a good text to CAD prompt
- Name the part (wall hook, L-bracket, enclosure)
- Give overall dimensions in millimeters
- Call out holes, wall thickness, and critical features
- Keep scope to one small printable part
Example: A 30mm wall hook with a 4mm screw hole and a 25mm arm
