3D-Tool review
A Windows CAD viewer with deep analysis tools, broad format support and one-time paid licenses.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
3D-Tool is a Windows desktop CAD viewer and converter for companies working with engineering and manufacturing data. It is designed for teams that need to inspect, measure, annotate and analyze 3D models or 2D drawings without requiring a full CAD system. The product supports more than 30 CAD formats, including DWG, DXF, STEP, STL, CATIA, SolidWorks, Creo and Siemens NX formats. Its toolset covers measurements, 3D dimensions, notes, redline markups, cross-sections, exploded views and several forms of model analysis.
The main strength is depth beyond basic viewing. 3D-Tool can measure distances, angles, radii, wall thicknesses, clearances and areas, while also supporting tooling, collision, wall-thickness and model-comparison analysis. It connects with formats and systems including CATIA, Siemens NX, Creo, SolidWorks, Autodesk Inventor, Solid Edge, Rhino, AutoCAD, STEP, IGES, JT, Parasolid and SAT. That combination suits engineering and manufacturing workflows where review requires more than rotating a model or checking a drawing.
Pricing is based on perpetual, one-time purchases. The Basic plan costs 200 EUR and includes the viewer, basic 3D and 2D interfaces, DXF and DWG support, and advanced 3D interfaces. Advanced costs 400 EUR with the same listed highlights, while Premium costs 800 EUR and adds premium CAD interfaces, the 3D-NativeCAD Converter, and publishing to formats including 3D-PDF and 3D-HTML. A permanently free Free Viewer is available, and a 14-day free trial is offered. Choose 3D-Tool for Windows-based teams needing detailed CAD inspection and analysis; choose an alternative if you need another platform or broader free-format coverage.
