CAiD FAQs

Question 1

What is CAiD and its primary function?

Accepted Answer

CAiD is an MCP server that enables AI agents to perform validated 3D CAD modeling. It integrates with CAiD and OpenCASCADE (OCP) to execute precise design operations without a traditional GUI, making the modeling engine itself the server.

Question 2

How does CAiD ensure the reliability and validation of 3D CAD operations?

Accepted Answer

CAiD validates every geometry operation through its ForgeResult system. This system tracks changes in volume, surface area, and provides diagnostics, automatically catching common silent failures in CAD kernels like OCCT and providing detailed feedback.

Question 3

What types of CAD tasks can AI agents accomplish using CAiD?

Accepted Answer

AI agents can perform a wide range of tasks, including creating primitive shapes, applying modifications (fillets, holes, shells), transformations, boolean operations, detailed geometry querying, generating section cuts and exploded views, and managing multi-part assemblies.

Question 4

Can AI agents precisely target specific geometry features for modification?

Accepted Answer

Yes, CAiD features advanced geometry querying tools that allow AI agents to list edges and faces with unique indices. This enables precise, index-based selection for accurate modifications like filleting specific edges or adding holes to particular faces, solving the 'blind fillet' problem.

Question 5

What if an AI agent needs to perform a highly custom or advanced CAD operation?

Accepted Answer

CAiD provides an 'escape hatch' for direct scripting. AI agents can utilize the `run_cadquery_script` tool to execute custom Python code, giving full access to the underlying CAiD and OCP libraries for advanced or non-standard modeling tasks.
