Capabilities

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.

How it works

From idea to CAD-ready prototype

Three steps. Seconds, not hours.

01

Describe

Type what you need in plain English — or upload a PDF, photo, or scan to refine an existing drawing.

02

Generate

The AI writes parametric code and runs it in a sandbox to produce real, editable geometry.

03

Refine & export

Tweak it by chat until it’s right, then download STEP, STL, DXF, OBJ, or a PDF drawing.

Use cases

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.

STEPDXF

3D printing & makers

Printable parts with clean manifold geometry and the right wall thickness.

STLOBJ

Architects & drafters

Floor plans, layouts, and MEP overlays drawn to AS1100 / ISO.

DXFPDF

Robotics & drones

Frames, mounts, and chassis you can assemble and iterate on fast.

STEPSTL

Hardware startups

Go from idea to prototype-ready concept before the kickoff meeting ends.

STEPPDF

Students & education

Learn CAD by describing intent and reading the geometry it produces.

Loved by builders

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.”

Priya N.
Mechanical Engineer

“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.”

Marcus T.
Building Designer

“As a hardware founder I prototype enclosures constantly. AiCADGen gets me to a printable STL fast, then I iterate by chat. Genuinely saves days.”

About the outputs

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.

Describe the part. AiCADGen builds the concept.

10 free credits. No credit card. You’ll know in under a minute whether it saves you time.
