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.

Bentley Systems offers the MicroStation application and product family as a 3D and 2D modeling and computer-aided design (CAD) solution for engineers and designers.
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.
MicroStation is THE program to use for roadway and corridor modeling. Most departments of transportation and municipalities in my region require that the models be delivered in the dgn format, so it is MicroStation or bust. It is an absolute pain to use some of the add-in features though. Things that are easy in other programs like making smart tables that update with the latest information usually necessitate the use of Axiom or similar outside programs/add-ins. I design storm sewer systems, and it takes us 6 months to train up new hires on this software, because it is NOT intuitive. You need to know which buttons to press, since it is not designed to be easily command-based like AutoCAD Civil 3D.
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.
MicroStation is very hard to use for our newest employees. It is not intuitive, and you need to know where to find the buttons to perform the commands you would like to perform instead of typing in the commands like other similar modeling programs. Also, it has no good traffic turning add-ins. We continue to run ALL our turning in Autoturn, since this is not a usable feature with MicroStation.
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.
The only general purpose CAD program that you can compare MicroStation with would be AutoCAD. MicroStation, in my opinion, is a superior product in every way but one. That one issue is that there are just more people who have and know how to use AutoCAD than there are ones who know MicroStation. This makes AutoCAD easier to get up and running for most firms.
