Compliance
Launch CBECC Result Tool →
CBECC Result Tool
LEED EAp2-4/5 & CBECC performance rating method compliance aggregator. Parses simulation output HTML reports to produce standard 67-column LEED MDL CSVs and Excel summaries.
- Electricity & Gas end-use breakdowns
- Dynamic baseline averaging (ab1–ab4)
- Interactive Chart.js visual summaries
- LEED standard template CSV / Excel export
CAD Engine
Launch PDF to DWG Converter →
PDF to Clean DWG Converter
Converts Bluebeam polygon markup annotations on PDFs into clean, orthogonal single-line DWG/DXF files with closed polyloops for Revit, ArchiCAD, and energy models.
- Automatic scale & multi-level layer detection
- Single-line shared wall deduplication
- Strict orthogonal snapping (±5°)
- Guaranteed 0 open ends (clean polyloop)
- Interactive multi-level overlay inspector
- Spread-out export (120% spacing) & origin aligned

Launch Space PolyLoop Checking Tool →
CBECC Space PolyLoop Checking Tool
Detects missing space PolyLoops and area mismatches (>5% deviation from child floors) in CBECC input files (.cibd, .cibd10, .cibd19, .cibd22, .cibd25i), automatically generates clean boundary loops by unioning child floors, and heals model geometry.
- Automatic detection of spaces missing PolyLp or with area mismatch (>5%)
- Shapely union of child floors (IntFlr, ExtFlr, UndgrFlr)
- Interactive 2D CAD canvas with zoom, pan, and existing vs union overlay
- In-place coordinate editor (add, remove, adjust)
- Safe unique entity ID allocation (PolyLoop & CartesianPoint)
- One-click batch repair & direct .cibd export
