What is text to CAD?
Text to CAD is the process of turning a written description of a part into a 3D CAD model. Instead of drawing geometry by hand in traditional CAD software, you describe the dimensions and features you need in plain English, and an AI engine generates an editable parametric model.
How text to CAD works
A text to CAD engine reads your prompt and maps it to modeling operations such as extrudes, holes, fillets, and patterns. The result is not a flat picture. It is a real parametric model where each dimension is a value you can change. With TextoCAD, those values appear as sliders so you can refine the design after the first generation.
A simple example
Suppose you need a mounting plate. You might write: "Create a 100 by 60 mm plate, 4 mm thick, with four 5 mm holes set 10 mm from each corner." The engine produces that plate as an editable model. If you later need thicker material, you move the thickness slider instead of rebuilding the part.
How it differs from traditional CAD
Traditional CAD gives you precise control but expects you to build every feature manually, which has a steep learning curve. Text to CAD lowers that barrier by generating a working starting model from your description. You still get parametric control, but you reach a usable model much faster.

Frequently asked questions
Is text to CAD the same as AI CAD?
They overlap. AI CAD is a broad term for using artificial intelligence in computer aided design. Text to CAD is one specific approach where the input is a written description and the output is a CAD model.
Does text to CAD replace CAD engineers?
No. Text to CAD speeds up early modeling and simple parts, but complex assemblies, tolerancing, and manufacturing decisions still need an experienced engineer. It is a tool that helps both beginners and professionals work faster.
What kinds of parts work best with text to CAD?
Simple, well defined mechanical parts work best: brackets, plates, enclosures, bushings, flanges, spacers, and gears. These have clear dimensions that are easy to describe in a prompt.
