Afanche 3D STEP Viewer is a professional level 3D STEP (.stp or .step) file viewer for Windows PC. STEP format (ISO 10303) is an ISO standard for 3D data exchange. It is widely supported by almost all 3D CAD, CAM, CAE, PLM applications including CATIA, Autodesk Inventor, SolidWorks, NX, ProE (PTC Creo, ProEngineer), etc. It is a great tool for visualizing, measuring, analyzing, converting, modifying and collaborating on a variety of 3D models. Our modern design makes it very easy to use (there is practically no learning curve) and the app is super fast. The price of the software is just a fraction of similar products offered by our competitors. Main features include: Open 3D STEP files in .stp or .step extension; View models in 3D. Spin, pan, zoom in/out with perspective or orthographic projection; Measure distance, location, volume, area, length, radius, angle, thickness, boundary and many more; Open multiple files in the same window, very useful for assembly viewing or model comparison; Turn individual parts on and off to better view the model; Support 3D notes and 3D dimensions for better presentation and communication; Support comment and asset management for better collaboration and record keeping; Scale, translate, mirror, rotate individual 3D part; Slice 3D model at any given position, very useful for 3D model repair and modification; Provide many useful features for 3D printing, including: check 3D model against build volume of 3D printer, fit 3D model with build volume, and many others; Export 3D model in STL, DAE, DXF, 3DS, OBJ, VRML, PLY, OFF, 3D HTML and ATD format, very useful for 3D format conversion; Export 3D rendering image in JPEG format; Support direct printing of 3D rendering; Dedicated video card including NVIDIA or AMD ATI is required to run the application.
