Civil 3D / AutoCAD .NET API knowledge base — 48 skills, 6 MCP tools, 4 agents, 8,330 types
Explores the Civil 3D and AutoCAD .NET API to find types, methods, and patterns for a given development task. Combines database lookups with skill recommendations and developer guide references.
Reviews C# code that uses Civil 3D or AutoCAD .NET APIs for correctness — verifies class names, method signatures, parameter types, enum values, and obsolete usage against the API database
Reviews c3d-api SKILL.md files for format compliance, API accuracy, missing gotchas, stale cross-references, and consistency with other skills in the plugin
Creates new SKILL.md files for the c3d-api plugin by researching the AutoCAD/Civil 3D .NET API, following established format conventions, and incorporating real codebase patterns from the C3D Plugins project
Block definitions, references, attributes, dynamic block properties, exploding
Database cloning, DeepClone, WblockClone, IdMapping, side databases, Purge, Audit
Dimensions — aligned, rotated, arc, radial, angular, ordinate, text overrides
Editor prompts — point, entity, selection, string, keyword, TypedValue filters
