Partwright 1.10 adds AI plan cards and a read-only planning fix for 3D modelling

Partwright’s [October 27 version 1.10 release](https://www.partwrightstudio.com/whats‑new) gives its AI chat dedicated cards for questions and plans. Users can answer a clarifying question or approve a proposed plan through those cards. The same release reports a fix to plan mode: it no longer changes the model, and the assistant’s clarifying questions are handled properly. In an AI‑assisted modelling workflow, those changes concern the handoff between discussing a design and changing it. The changelog describes clearer response controls and a read‑only planning fix. It does not establish that every possible editing action is subject to a universal approval gate, and OpenTools has not tested the mode’s behavior.

Partwright describes itself as a [browser‑native parametric CAD studio with an API for AI agents](https://www.partwrightstudio.com/). Its workflow combines model code, a rendered geometry view and export formats used in 3D modelling. That gives the plan‑card update a specific creator task: reviewing what an assistant proposes to do to a model, rather than simply receiving a longer chat response. The [1.10 notes](https://www.partwrightstudio.com/whats‑new) also list multi‑file STL or 3MF import and painted‑region clean‑up operations. Those are surrounding editor changes, rather than separate AI releases. The developer calls 1.10 backward compatible and says existing sessions and exported files continue to work; that is a release claim, not a migration test performed by OpenTools.

The new controls help distinguish a proposal from the model‑changing work that follows. The project’s terms separately warn that generated geometry may be wrong, non‑manifold, not watertight or otherwise unsuitable for manufacturing, and tell users to inspect and validate models before relying on them. Approving an assistant’s plan does not by itself establish that an exported object is fit to print or machine.

Partwright is source‑available and free for non‑commercial use under its stated PolyForm Noncommercial License 1.0.0; the terms reserve commercial rights. They also say requests made through a connected AI provider are billed to the user’s provider account. Those software‑use and cost terms remain relevant when evaluating the new planning interface.
