Innerscene Universal 3D Viewer
Innerscene Universal 3D Viewer is a free tool for opening CAD and mesh files directly in your web browser, with nothing to install. It reads 17+ formats, including SketchUp (.skp), AutoCAD (.dwg, .dxf), STEP, Rhino (.3dm), glTF/GLB, OBJ, STL, FBX, PLY, 3DS, 3MF, COLLADA, VRML, and X3D, so you no longer need a separate app for each file a collaborator sends.
Files are parsed and rendered locally in your browser and are not uploaded by default, which keeps proprietary and NDA work on your own machine. You can inspect layers, switch render modes, take measurements, and convert geometry to STL, OBJ, GLB, or PDF. Share links preserve the camera, lighting, and layer state, and a one line iframe snippet embeds the viewer in any page.
Built by Innerscene, a maker of artificial skylights, to open the many formats architects, engineers, and vendors kept sending. Free to use, no account required.

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.

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.

Microsoft 3D Viewer
Easily view 3D models and animations in real time. 3D Viewer lets you view 3D models with lighting controls, inspect model data and visualize different shading modes. In Mixed Reality mode, combine the digital and physical. Push the boundaries of reality and capture it all with a video or photo to share. Quickly view common 3D file types: FBX, STL, OBJ, GLB, GLTF, PLY, and 3MF, with high-quality staging. Use simple pan, zoom, and orbiting controls with your mouse, touch, pen, or keyboard. Inspect the 3D model’s mesh, texture, material, and animation data. View 3D files in different shading modes such as smooth, wireframe on smooth, texture passes, and more. Control the position and color of the staging lights. 3D Viewer version 7.2003.11022.0 and later versions include important security updates.
