Open Cascade CAD Assistant is a powerful offline 3D CAD viewer and converter with simple and intuitive interface, free for both personal and commercial use. Originally developed as a testbed and showcase for the Open CASCADE Technology on mobile platforms, the solution has been appreciated as fast and handy 3D viewer by thousands of end-users on mobiles and desktops worldwide. CAD Assistant brings the power of open technologies to the hands of engineers working with 3D data. CAD Assistant is based on open source libraries (Open CASCADE Technology, Qt, FreeType, FreeImage, etc.) and employs open formats for CAD and mesh data (STEP, IFC, IGES, BREP, glTF, JT, PLY, STL, OBJ, 3DM). It also supports a set of other file formats like DXF, SAT (ACIS), XT (Parasolid). Viewing mesh models with associated data is an additional functionality included in CAD Assistant. Mesh can be read from files in PLY format.
