What it can do
- Generates FeatureScript, inserts it into a Feature Studio in an Onshape document, runs it and reads back errors so the assistant can revise the code.
- Lets the assistant inspect the geometry the code produces.
- Produces reusable parametric custom features that keep working without the AI once written.
Limitations
- Early access through Onshape Labs; Onshape advises treating output like a new teammate's first draft.
- Writes FeatureScript code rather than modelling parts feature by feature.
- Requires subscribing to the server in the Onshape App Store; plan requirements and cost are not stated on Onshape's pages.
