VRML or WRL - ISO 14772 virtual reality modeling language (ASCII format).Supported data: triangulation and quads, plain list of named groups, common materials with texture maps.

OBJ Wavefront - format for 3D assets exchange commonly supported by modeling systems and game engines (ASCII format).Supported data: shape geometry and assembly structure (defined by nested compounds, without names). BREP - ASCII persistence of shape Boundary representation used by OCCT with open specification.Format accumulates persistence of various data which can be imported from other files formats like STEP, IGES, ACIS, glTF, etc. XBF - BinXCAF, which is a binary persistence format for universal XCAF document structure used by OCCT.

Supported data: shape geometry (triangulation), assembly structure, PBR metallic-roughness materials with texture maps, names.

glTF - API-neutral runtime asset delivery format (ASCII or binary), commonly supported by modeling systems and game engines.

Supported data: shape geometry, colors, top-level object names, file information.

IGES (5.1 and 5.3) - vendor-neutral format for data exchange among CAD systems (ASCII format).

Supported data: shape geometry, assembly structure, colors, names, validation properties, file information, dimensions and tolerances (semantic and tessellated PMI).

STEP (AP203, AP214 and AP242) - ISO 10303 standard for product data representation and exchange among CAD systems (ASCII format).

The program supports the following file formats:

iOS: install from App Store or get IPA archive.īasic functionality is provided by XDE component of Open CASCADE Technology (OCCT).

Android: install from Google Play or download APK ( ARM 32-bit, ARM 64-bit, x86_64).

macOS: install from DMG package ( Intel x86_64, ARM 64-bit).

Windows: download installer or ZIP archive (x86_64).

Use the following links to download and install the latest version of CAD Assistant - v.1.6.0 () for your platform (the installers are available on the old version of the website, please, sign up or login if you have signed up earlier): It also supports a set of other file formats like DXF, SAT (ACIS), XT (Parasolid). 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).
