The genuinely useful test is whether an agent can modify a dimensioned mechanical part and keep the geometry editable. That is more valuable to your vise and fixture projects than making a visually plausible but uneditable mesh.

What to do: Try the browser demo with a simple bracket and two hole dimensions. Inspect actual export capabilities and geometric accuracy before adopting it; the project is young.

An open-source CAD program lets an AI agent build and change parametric parts. SolidCraft is an experimental Rust-based CAD application with sketches, constraints, a feature timeline and a built-in MCP interface for AI-driven modeling. Its project page offers macOS builds and a browser demo. What to do: Try the browser demo with a simple bracket and two hole dimensions.
