The record

Purpose: CAD Assistant is an offline 3D CAD viewer and converter for personal and commercial use.
File formats: It supports CAD and mesh formats including STEP, IFC, IGES, BREP, glTF, JT, PLY, STL, OBJ and 3DM, plus DXF, SAT and Parasolid XT.
Model inspection: Users can browse assembly trees, show or hide components, and inspect product and geometric properties such as area, volume and centroid.
Mesh analysis: It can display PLY mesh data in wireframe, shaded and shrink modes, with color or scalar quantities mapped to mesh elements or nodes.
Rendering: Desktop versions include a GPU-accelerated path-tracing renderer for photo-realistic screenshots.
Integrations: The application integrates with operating-system file associations so compatible apps can open relevant files in CAD Assistant; saved model images can be attached through a mail client.
Offline and local use: The maker’s brochure says no server connection is needed and that processing is performed locally on the device.
Commercial import limit: Imports provided by commercial Open Cascade components disallow model export or conversion, while the maker says models retain complete structure without model-size limits.
Device limits: The maker warns that large files may take time, low-range GPUs may be slow, and scenes with several million triangles may be terminated by the system; it says files under 50 MB are generally safe on most devices.
Support: The product page directs users to forums for comments and invites bug reports, questions and suggestions through its contact options.
Warranty: The application is provided as is, without warranty of any kind.
Current listed release: The product page lists version 1.6.0 dated 2021-10-05 as the latest version.
Headquarters: Issy-les-Moulineaux, France
Price from: Free
