...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.
