engineering-drawing-prep

Automated pre-design document preparation for engineering projects. Standardize client DWGs, audit deliverables, extract data tables, and generate RFIs before real design begins.

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

bash

# 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)
