CADProps - Free browser CAD viewer, 92 formats
CADProps is a free browser CAD viewer and converter for teams that need to open and measure files without installing desktop software. It supports 92 extensions, including DWG, DXF, STEP, IGES, STL, and 3MF. Neutral and mesh formats can be checked in the browser. Native vendor formats such as CATIA, NX, Inventor, and SolidWorks are processed on CADProps servers rather than parsed only on the local machine. Ethan Tan is the CTO. The tool is meant for a quick view, a dimension check, or a format conversion before a full CAD seat is opened. It does not replace solid editing inside desktop CAD.
