Real AiCADGen output — every part, the assembly, and the drawing came from these prompts.
Build yours freeTurn ideas into real engineering designs with AI
Generate CAD models, parts, assemblies, and drawings from a simple text prompt.
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 manufacturable, exportable 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.
Manufacturing-ready
Standards-aware drawings, material hints, and tolerance notes that move a design toward the shop floor.
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 engineers, makers, founders, and product designers
One credit pool across every workflow — parts, assemblies, plans, and drawings.
Mechanical engineers
Brackets, plates, shafts, enclosures — parametric and CAM-ready.
3D printing & makers
Printable parts with clean manifold geometry and the right wall thickness.
Architects & drafters
Floor plans, layouts, and MEP overlays drawn to AS1100 / ISO.
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.
Students & education
Learn CAD by describing intent and reading the geometry it produces.
Teams ship hardware faster with AiCADGen
“I described a mounting bracket in one sentence and had a STEP file in our assembly before lunch. The chat refinement is the killer feature.”
“Floor-plan drafts that used to eat an afternoon now take minutes. The MEP overlays drop straight onto an existing plan — exactly the workflow I wanted.”
“As a hardware founder I prototype enclosures constantly. AiCADGen gets me to a printable STL fast, then I iterate by chat. Genuinely saves days.”
Start free. Scale when you ship.
Every plan draws from one credit pool. Paid plans from $12/mo.
AiCADGen is a drafting accelerator, not a replacement for licensed-engineer sign-off. Outputs are prototype-quality and designed for iteration. Best inputs include clear constraints, dimensions, and any reference standards. Always verify before manufacturing, fabrication, or installation. Model accuracy improves each release; a failed generation is still charged a small fee for the AI work already done.
