## FAQ

### What can MakerSim simulate?

It simulates how force travels through a 3D-printed part using an elasticity solver to return relative stress heatmaps and movement previews.

### Does MakerSim predict part failure?

No, the results are intended for design exploration and do not predict failure or establish safe working loads.

### How do I connect an MCP client to MakerSim?

You can use the makersim-mcp executable as a stdio server by adding it to your mcpServers configuration with the absolute path to the executable.

### What programming languages are required for the workflow?

Python 3.11+ and uv are sufficient for the CLI/MCP workflow, while Node.js and a browser are needed for the viewer.
