Parser demo
Small-scale demonstration of how drawings become structured building data.
This demo uses simplified geometry and generated layout data. Production parsing connects DXF/DWG/IFC files to a CAD worker.
Input source
Loads the built-in mini floor plan and runs the full pipeline.

- · Total spaces: 5
Object graph
Demo activeBuilds the node/edge graph that links rooms to walls, doors, windows, materials, and cost items.
- · 32 nodes
- · 74 edges
- · 22 cost-linked objects
Rule engine
Demo activeDeterministic checks against company rules and life-safety basics.
- · 1 high · 0 medium · 0 low
- · 7 passing checks
Cost mapper
Demo activeMaps detected objects into cost items using the material library + project rates.
- · 6 cost lines
- · 71,080 QAR estimated
Export
ActiveLayout JSON, object graph JSON, parser report CSV, cost mapping CSV available now. Production CAD worker adds DXF, IFC, FreeCAD, and DWG export.
- · Layout JSON
- · Object Graph JSON
- · Parser Report CSV
- · Cost Mapping CSV

| Gap + arc | Door | 91% | Opening between corridor and room | D-002 |
| Thin segment on exterior wall | Window | 88% | Exterior-facing opening | W-001 |
| Small service room label | MEP Room | 94% | Service keyword + adjacency to corridor | MEP Room |
| Long thin polyline | Corridor | 92% | Aspect ratio + connects multiple rooms | Corridor |

Exports & handoff
Small-scale demo meaning: this page shows the same pipeline a production CAD worker would run on larger DXF/DWG/IFC files. The demo uses simplified structured geometry so the workflow is visible: objects are detected, classified, connected into a graph, reviewed by rules, mapped to cost items, and exported. Engineering and QS approval is still required for any production output.
