Real AiCADGen output — every part, the assembly, and the drawing came from these prompts.
Build yours freeDescribe a part. Download a printable STL in under a minute.
From a one-line prompt to real, editable CAD — export STL for your printer, or STEP, DXF, OBJ and PDF for CAM and the shop floor. Parts, assemblies, and drawings.
No credit card required · Generate your first CAD model in minutes
Generate parts, assemblies,
and drawings faster
A full text-to-CAD pipeline — from a one-line prompt to exportable concept and prototype files.
Text-to-CAD generation
Describe the part. AiCADGen builds the concept — real parametric geometry, not a picture of one.
Real exportable files
Export STL, STEP, DXF, OBJ, and PDF drawings. Drop straight into CAM, a slicer, or your CAD package.
Floor plans & MEP
Draft layouts from a brief, or overlay HVAC, electrical, and structural services onto an existing plan.
Mechanical assemblies
Multi-part assemblies export a true STEP assembly with per-part files and a mate-intent manifest.
Refine by chat
“Make the holes 8mm.” “Move the kitchen wall 600mm east.” Iterate in seconds, not hours.
Shop-floor formats
Standards-aware drawings, material hints, and tolerance notes that move a concept toward the shop floor — for engineer review, not straight to production.
Order prints — no printer needed
Don’t own a 3D printer? Have your part printed and shipped to you in supported regions, straight from the design.
From idea to CAD-ready prototype
Three steps. Seconds, not hours.
Describe
Type what you need in plain English — or upload a PDF, photo, or scan to refine an existing drawing.
Generate
The AI writes parametric code and runs it in a sandbox to produce real, editable geometry.
Refine & export
Tweak it by chat until it’s right, then download STEP, STL, DXF, OBJ, or a PDF drawing.
Built for makers, engineers, founders, and product designers
One credit pool across every workflow — parts, assemblies, plans, and drawings.
3D printing & makers
Custom functional parts, mounts, and replacements — printable STL with clean manifold geometry and the right wall thickness. Slice and print the same day.
Mechanical engineers
Brackets, plates, shafts, enclosures — parametric and CAM-ready.
Robotics & drones
Frames, mounts, and chassis you can assemble and iterate on fast.
Hardware startups
Go from idea to prototype-ready concept before the kickoff meeting ends.
Architects & drafters
Floor plans, layouts, and MEP overlays drawn to AS1100 / ISO.
Students & education
Learn CAD by describing intent and reading the geometry it produces.
Real CAD you can actually use
Not a mesh trick or a picture — editable geometry and exportable files: STEP, STL, DXF and dimensioned PDF drawings.
Real parametric CAD, not an AI picture
The model writes geometry code and runs it in a sandbox to produce true, editable CAD — geometry you can refine, not a rendered image of a part.
Files that drop into your workflow
Export STL, STEP, DXF, OBJ, PDF drawings, and ready-to-print G-code — straight into a slicer, your CAM setup, or your CAD package.
Free to design — pay only to export
No card to start. Describe a part and refine it by chat until the geometry is right, then unlock the CAD files when you actually need them — one design at a time, or unlimited on a plan.
Start free. Scale when you ship.
Every plan draws from one credit pool. Memberships from $5/mo.
AiCADGen is a drafting accelerator, not a replacement for licensed-engineer sign-off. Everything it produces is for conceptual design and prototyping only. No load case is applied, no design standard or building code is checked, and no engineer has reviewed the result — every drawing is stamped “CONCEPT / PROTOTYPE ONLY — NOT FOR CONSTRUCTION” for that reason. Have a qualified engineer verify and approve any design against the standards that apply to you before it is manufactured, fabricated or installed. Best inputs include clear constraints, dimensions, and any reference standards. Model accuracy improves each release. On the free plan a failed generation costs you nothing; on paid plans failures are charged at cost only — you never pay margin on a design that didn't succeed.
