ProtoTech's DWG/DXF Compare is an AutoCAD plugin for designers and drafters who need to spot changes between two drawing revisions.
It compares two DWG or DXF files and shows the differences directly in AutoCAD with color-coded entities for unchanged, modified, deleted, and added items.
The comparison result can also be saved to a new file for later review or sharing.

OBJ Exporter for AutoCAD is a Windows plugin from ProtoTech Solutions that converts AutoCAD DWG and DXF models into OBJ files for use in visualization, game engines, and other 3D pipelines. It preserves face-level colors and layer structure, and lets users control output size and quality with adjustable precision and facet-tolerance settings.
Takes two versions of the same drawing set and tells you exactly what changed between them, sheet by sheet. It surfaces specific MEP, architectural, and civil change. Each finding is tagged with discipline, severity, and confidence, with a box drawn around the exact spot on the page so reviewers can click straight to it. This tool is especially valuable for multi-discipline coordination and prototype or chain projects where the same set iterates many times.
ProtoTech's STEP Exporter for AutoCAD converts AutoCAD drawings into STEP file format (AP203, AP214, AP242), preserving colors, wireframe geometry and hidden entities. It's built for engineers, designers and manufacturers who need to exchange CAD models with other platforms such as SolidWorks, CATIA, Creo and NX.
