3D-Tool
Open and see any 3D part or assembly clearly—without expensive CAD software.
3D‑Tool lets you open, view, measure, and mark-up 3D CAD models in a simple, affordable way. Designers, engineers, and project managers can review parts from many CAD systems without needing the original software. The Premium and Advanced versions support 20+ file formats and let you share annotated models with anyone using the Free Viewer app. The Free Viewer opens native 3D‑Tool files (Those exported by a paid version of 3D-Tool) and STL files, making collaboration easy. The Premium version adds a powerful converter that turns native CAD files into STEP or CAT formats for use in NC, CMM, and other systems that can’t open the originals.
