Engineers and professionals interested in an offline 3D CAD viewer and converter solution to visualize and convert their CAD files
About CAD Assistant
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.

3D_Analyzer
3D CAD Viewer to review and analyze models from all major native and standard CAD formats with assemblies-structure, B-rep, tesselation, features and parameter as well as metadata, PMI and annotations. Precise measuring, cut and annotation functions based on B-REP Models. Fast Creation of exploded views with automatic and manual functions. 3D_Analyzer is the perfect tool for project management tasks. It is not only a Viewer for all major CAD formats, it also provides a wide range of easy to use and powerful 3D inspection computations such as comparison of geometry, PMI and assembly-structure, collision and clearance detection as well as wall thickness, draft and undercut analysis. Share your files, you can easily export the CAD files to the 3D-PDF format. Additionally you can also save the analysis results to 3D-PDF and exchange it with your colleagues, suppliers or customers.

3D-Tool
Open and see any 3D part or assembly clearly—without expensive CAD software.
3D‑Tool lets you open, view, measure, and mark-up 3D CAD models in a simple, affordable way. Designers, engineers, and project managers can review parts from many CAD systems without needing the original software. The Premium and Advanced versions support 20+ file formats and let you share annotated models with anyone using the Free Viewer app. The Free Viewer opens native 3D‑Tool files (Those exported by a paid version of 3D-Tool) and STL files, making collaboration easy. The Premium version adds a powerful converter that turns native CAD files into STEP or CAT formats for use in NC, CMM, and other systems that can’t open the originals.

MeshLab
The open source system for processing and editing 3D triangular meshes. It provides a set of tools for editing, cleaning, healing, inspecting, rendering, texturing and converting meshes. It offers features for processing raw data produced by 3D digitization tools/devices and for preparing models for 3D printing. In this version we introduce support to several file formats (.gltf, .glb, .nxs, .nxz, .e57) and a brand new plugin for exact mesh booleans. The 3D data alignment phase (also known as registration) is a fundamental step in the pipeline for processing 3D scanned data. MeshLab provides a powerful tool for moving the different meshes into a common reference system, able to manage large set of range-maps. MeshLab implements a fine tuned ICP one-to-one alignment step, followed by a global bundle adjustment error-distribution step. The alignment can be performed on meshes and point clouds coming from several sources, including active (both short- and long-range) scanners.

Bentley View
In addition to viewing 3D models, you can use Bentley View as a free CAD viewer with capabilities to search for objects, measure distances and areas accurately, and print drawings to scale with full fidelity, on every desktop, for free. With millions of users, Bentley View is the industry's most powerful free viewer. In addition to being the most popular AutoCAD reader, you can view over 50 file formats, including CAD and raster images as well as Bentley's uniquely powerful iModels. You can easily open DWG and open DXF designs with the same fidelity as the authoring software. More than just a free DWG viewer, some of Bentley View’s recent enhancements in the latest CONNECT Edition include newly added format support and advanced viewing features. If all you need is to view CAD files, then Bentley View is a great free solution! If you also need to edit them to generate drawings, models, and visualizations, you might consider MicroStation PowerDraft.
