CADLook Advanced Viewer is a light-weight, cost-effective tool to visualize and inspect CAD files in international standard formats without the heavy-duty CAD systems. It handles the idiosyncrasy of files from various systems with unrivalled robustness. You can load a mixture of multiple files from different file formats (ACIS, Parasolid, IGES, STEP, VDA-FS or G-code) into one session.
