description
Use when extracting plan-view architectural geometry from DXF files with semantic CAD layers, especially when outputs must normalize rooms, doors, fixtures, clearances, and grab bars into machine-checkable JSON.
Use this skill for 2D architectural DXF plans where the CAD file is the authoritative source. Treat screenshots as orientation only.
Workflow
- Open the DXF with
ezdxf.readfile(...)and inspect modelspace entities grouped byentity.dxf.layer. - Build a layer inventory before extracting geometry. Include entity counts and entity types per layer.
- Normalize layer aliases through the provided layer schema. Keep both the original layer name and the canonical meaning in your working notes.
- Extract plan-view geometry in drawing units. If the task declares inches, do not convert unless the DXF header proves a different unit.
- Prefer geometric primitives over image interpretation:
LINEand lightweight/polyline vertices for wall, door, fixture, clearance, and grab-bar outlines.CIRCLEcenter/radius for turning circles or circular fixture details.ARCandSPLINEextents only after checking whether they are visible fixture geometry or control geometry.
