CAiD

Validated 3D CAD modeling for AI agents via CAiD and OpenCASCADE, providing 54 tools with geometry validation, volume tracking, and automatic failure detection.

Validated 3D CAD modeling server built on CAiD and OpenCASCADE (via OCP). Provides 54 tools across 13 categories including primitives, boolean operations, fillets, measurements, section views, and assemblies. Every geometry operation returns validation results with volume tracking and diagnostics, automatically catching silent OCCT failures. Supports geometry query and inspection tools that let agents understand what they've built before modifying it, solving the "blind fillet" problem with index-based edge and face selection.
