MeshLab
Open source software for editing and processing 3D triangular meshes. It includes tools for editing, cleaning and healing, inspecting, inspecting, inspecting, rendering texturing, texturing, and converting meshes. It can process raw data from 3D digitization devices/tools, and prepare models for 3D printing. This version supports several file formats (.gltf.glb.nxs.nxz.e57) as well as a plugin for exact meshbooleans. The 3D data alignment phase, also known as registration, is an essential step in the process of processing 3D scanned data. MeshLab is a powerful tool that allows you to move the different meshes into one common reference system. It can also manage large range-maps. MeshLab uses a fine-tuned ICP one-to-1 alignment step, followed with a global bundle adjustment error distribution step. The alignment can be done on point clouds and meshes from multiple sources, including active scanners (both short-range and long-range).

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. B-REP Models allow for precise measuring, cut, and annotation functions. Rapid creation of exploded views using both automatic and manual functions. 3D_Analyzer can be used to manage project tasks. It can be used as a Viewer for all major CAD files. It also offers a wide range easy-to-use and powerful 3D inspection computations, such as collision detection, collision detection, PMI, assembly-structure, collision and clearance detection, wall thickness, draft, and undercut analysis. You can share your files by exporting the CAD files to 3D-PDF format. You can also save your analysis results to 3D PDF and share them with colleagues, suppliers, or customers.

ABViewer
ABViewer is a universal software for working with drawings on the PC. It allows you to view, edit and convert DWG files and other CAD files. You can either work with a single fragment of a drawing, or with a group. All this at a very affordable price! ABViewer can convert single files or a whole group of files. Batch conversion allows you to choose from a variety of export settings such as black-and-white mode or specifying the file size. The 3D panel allows you to set up visual displays of 3D models and sections planes. The panel can be used in 3D Viewer mode. You can customize 3D model viewing with the commands and options available in the 3D Section panel. The settings at the top of your form allow you to display sections and gizmos of a model. You can create multiple planes at once.

CAD Assistant
Open CascadeCAD Assistant is an offline 3D CAD viewer/converter with an intuitive interface. It is free for personal and commercial use. The solution was originally developed to showcase the Open CASCADE Technology on mobile platforms. It has been widely used by thousands of users on desktops and mobiles around the world as a fast and useful 3D viewer. CAD Assistant puts the power of open technologies in the hands of engineers who work with 3D data. CAD Assistant is based upon open source libraries (Open CASCADE Technology Qt, FreeType and FreeImage, etc.). Open formats are available for CAD and mesh data (STEP and IFC, IGES and BREP), glTF and JT, PLY STL, OBJ and 3DM. It supports a variety of file formats, including DXF and SAT (ACIS), XT(Parasolid). Additional functionality in CAD Assistant includes the ability to view mesh models and associated data. You can read files in PLY format to view mesh.
