Business Case
Problem Statement
AutoCAD DWG files contain valuable project data locked in proprietary format:
Layer structures with drawing organization
Block references with attribute data
Text annotations and dimensions
Geometric entities (lines, polylines, arcs)
External references (xrefs)
Extracting this data typically requires AutoCAD licenses or complex programming.
Solution
DwgExporter.exe converts DWG files to structured Excel databases offline, without Autodesk licenses.
Business Value
Zero license cost - No AutoCAD license required
Legacy support - Reads DWG files from 1983 to 2026
Data extraction - Layers, blocks, attributes, text, geometry
