MeshMixer is a 3D design and modeling tool for 3D printing or scanning, supported by Autodesk (acquired 2011). While not discontinued, the product will not receive updates and Autodesk states they intend to include all functionality in updates of Fusion 360.

GrabCAD Workbench was a CAD collaboration solution that helps designers to manage files and engage partners in the design process. Since August 2022 it has been discontinued.
Autodesk MeshMixer is best for repairing STL files and basic modifications toward 3D printing. It is excellent for hollowing out models and adding escape holes for SLA printing or lost-wax casting. Its CSG (Boolean) functions to combine different meshes are good too and seldom cause the program to crash. There is even an integrated algorithm to optimize the layout of multiple files on a print bed in case of small-batch production. Autodesk MeshMixer's sculpting tools are there yet limited and there are a few better alternatives. Best of all, it is completely free.
GrabCad Workbench is well suited for group projects, where all my team members can view the designs at the same time, and by integrating it with CAD software like SolidWorks, all my team members can see the live changes in the projects based on the recommendations received. I can also do conversations with my team, which are project-specific, thus reducing time in email and video conferences. For assemblies, I can generate a Bill of materials with a single click. However, there are some drawbacks like every member needs to have an account in order to sync files with everyone, and the platform requires good internet connectivity otherwise file uploading will be time-consuming.
The remeshing tool needs to be faster, as in some cases it takes up to a day of waiting time.
The sculpting tools need the addition of a proper brush for creating sharp creases and ridges.
The standard shape library is rather limited. It would be nice to have this connected to online repositories such as Thingiverse, MyMiniFactory, or Cults3D.
One major drawback is, that it cannot display sketches and drawing files, only solids and surfaces can be seen on this platform.
The platform sometimes becomes unstable, it lags when I try to upload complex assemblies. Hence, GrabCad teams need to work to improve the stability of the platform.
Using Blender for STL file preparation is like swatting a mosquito with a wrecking ball, plus its boolean functionalities can be glitchy. ZBrushCoreMini proved too limiting as a sculpting tool, but so did Autodesk MeshMixer, so I am sticking to Sculptris. Materialise Magics and Netfabb are somewhat better at STL file repair and offer more advanced functionalities. But Magics does not remesh as well and Autodesk MeshMixer is far more compact and faster than Netfabb, so remains my weapon of choice.
SOLIDWORKS PDM is great because it is connected with your windows explorer, so you can guarantee that you will get the most recent version of the file. You need to remember to regularly update your files when using GrabCAD. SOLIDWORKS PDM has a more useful interface, where you can see previews, find BOMs, and view configurations without opening any files or checking them out. GrabCAD was chosen as a starting point to get the team started and familiar with a PDM system with the intention that another PDM would be chosen at a later date
