engineering-drawing-prep
Automated pre-design document preparation for engineering projects. Standardize client DWGs, audit deliverables, extract data tables, and generate RFIs — before you open Civil 3D or Revit.
What It Does
| Stage | Input | Output |
|---|---|---|
| Intake | Raw client folder (DWG, PDF, XLSX, DOCX, SHX) | Inventory manifest + SHA-256 hashes |
| Standardization | Heterogeneous DWGs with mismatched layers/fonts/title blocks | Unified WIP DWGs + PDFs |
| Audit | Unvetted CAD files | QA report: proxy objects, missing refs, font issues, layout errors |
| Tabulation | Scattered Excel/Word schedules | Structured room, equipment, lighting, and MEP interface registers |
| RFI | Identified gaps (missing survey, CRS, benchmarks, broken refs) | Formal Request for Information documents |
| Archive | All processed files | Versioned, hashed, traceable WIP package |
What It Does NOT Do
- Does not create Civil 3D terrain, road, or drainage models.
- Does not author Revit/IFC models or perform clash detection.
- Does not perform load calculations, pipe sizing, or equipment selection.
- Does not produce statutory permit drawings or sealed construction documents.
Quick Start
# Place client deliverables in ./clientgiven/
# Run the intake audit
bash scripts/01_intake_audit.sh ./clientgiven/
# Standardize drawings
bash scripts/02_standardize.sh ./clientgiven/ ./output/wip/
# Generate tables and RFI
python scripts/03_tabulate_and_rfi.py ./clientgiven/ ./output/
Requirements
- AutoCAD 2020+ (for Core Console batch processing)
- Python 3.10+
- ezdxf / pyautocad (optional, for non-AutoCAD environments)
