Describe a part in a sentence, with reference images if you like, and the AI writes parametric build123d code and builds a solid model. Drag its parameters and watch it change, preview it in 3D, ask for changes, and export STEP / STL / 3MF / glTF.

A real project: the final version of this mini 4WD track (after 7 prompts and 3 parameter edits); the prompt shown is the first one. Every slider stop is rebuilt from the track’s own script.
Made for printing
Each one started as a prompt: a house that comes apart floor by floor, a gear latch, a windmill on a standard bearing, an assembled enclosure. Open any of them in 3D to turn it, zoom in and take it apart.
Prompt
From these pictures … build the whole house, every floor of it … I want it at 500 × 500 mm. Each floor should come apart so you can see inside. … Did you rebuild the cabinet doors and the drawers? I want a finer model.
Prompt
Make me a gear knob that works as a door latch. The knob goes through a hole in the door, its handle outside and the gear inside, with a straight bar meshing above and below the gear. Turning the gear pushes the two bars out to either side or pulls them back, locking the door.
Prompt
Make me a windmill … Shouldn’t the blades be pitched? Can the bearing be realistic, so it turns?
Prompt
A 3D-printable remote enclosure, modeled assembled: bottom shell, top cover, 4 snap fits, M2 standoffs for the PCB, 4 keycaps and a USB-C opening.
Prompt
Build box blocks that join together. Focus on how they connect, and make the joints strong.
Prompts are taken from the real conversations, long ones abridged. Models are as the AI built them; the posters only set color and view.
01
Describe what the part is for and its size, with reference images if you have them. An AI agent writes build123d code and builds the solid in an isolated sandbox, so you get an editable parametric model, not a frozen mesh.
02
Dimensions such as width, wall thickness, hole spacing and slot count become parameters. Change one and the model is rebuilt directly, without asking the AI to start over.
03
If the preview is not right, say what to change. Every revision is kept as a version you can go back to.
04
Fillets, chamfers, shells, patterns and holes all show in the 3D preview: what you see is the solid you export.
05
The AI can use standard parts from a built-in library, such as aluminum extrusions, mechanical parts and parametric templates, assemble several parts, and check where they overlap, touch or leave gaps.
06
Export STEP, STL, 3MF or glTF from the same project, for CAD exchange, printing or web preview.
MeshWish keeps the conversation, modeling, 3D preview, parameters and export in one workspace.
Enter the part’s purpose, dimensions, mounting style and constraints, with reference images if you like.
The AI writes build123d code, builds the solid in a sandbox and checks the geometry.
Turn the solid model around in the browser.
Keep the conversation going and say what to change; every revision is kept as a version.
Adjust width, wall thickness, hole pitch, slot count and other parameters directly.
Export STEP, STL, 3MF or glTF.
You describe a part, optionally with reference images, and the AI writes parametric build123d code and builds a solid model. You preview it in the browser, tune its parameters, ask for changes, and export STEP, STL, 3MF or glTF.
STEP, STL, 3MF and glTF, for CAD exchange, 3D printing and web preview.
Every build checks that the solid is valid and measures its bounding box and volume, and you see the whole solid in the preview. Models can still have errors in dimensions or fit, so check them before you make them and confirm they suit your material, printer and use.
A run is charged as the AI works, so simple parts use few credits and complex assemblies more. Sign-up credits are valid for one month, subscription credits expire at the end of each billing period and credit-pack credits are valid for 12 months.
