Data offered docs-verified: 2D drafting entities (lines, polylines, curves, circles, regions, hatches, text, dimensions, leaders, tables, layers, blocks, attributes) · editing operations (move, copy, rotate, scale, mirror, offset, trim, extend, fillet, chamfer, arrays) · SQLite scan and CAD-IR drawing understanding · semantic objects, constraints and dimension binding · 3D solids and operations · PDF/DXF/DWF/image export
Formats docs-verified: MCP stdio · DWG (input) · DXF · PDF · DWF · image
Access docs-verified: Free, MIT-licensed open source (licence from ENTRY metadata); requires AutoCAD installed and licensed on Windows, running as the same Windows user as the MCP client

Useful for

Use cases llm-inferred: Preflight-checked inspection and summary of existing DWG drawings before civils or drainage design review · Guarded, dry-run-verified layer, annotation and dimension clean-up of CAD deliverables before issue · Generating PDF plot and PNG visual evidence of drainage or civils layouts for internal QA
Audience llm-inferred: civils engineers · drainage engineers · BIM and CAD technicians · GIS and CAD analysts

Limitations

Constraints docs-verified: Beta software, intended for controlled local use with operator review rather than unattended changes to production drawings · Windows only; requires AutoCAD running as the same Windows user · Not claimed to comply with formal ISO, GB or ASME standards · Requires a local MCP client; no hosted or remote operation
