Autodesk MeshMixer vs. Rhino 3D

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.

Rhinoceros 3D is very well-suited for buildings with repetitive bay layouts as a design can be quickly be updated (span, number of bay, height etc) simply by updating a couple numerical sliders. It is also well suited to quickly update one model (for example Revit) based on the changes in another model (either another Revit model or an analysis model). Rhinoceros 3D is not well-suited for teams that are not interested in learning GrassHopper as most of Rhino's value is in GrassHopper.

• Auto-repair function works fast, and if it does not completely cover all problem areas, manual fixes will work 99.5% of the time.
• Remeshing algorithm is fairly slow but does a wonderful job in creating meshes with homogeneous or adaptive triangulation.
• It contains a comprehensive set of tools to optimize and prepare STL files for 3D printing, such as hollowing and support generation.

• Rhino3D is a great translator. I use it to take in customer models and then add optical components to it in a detailed and precise way.
• Rhino3D has excellent workflow from curves to surfaces making the translation from optical to mechanical seamless.
• Rhino3D can be paired with Grasshopper to create interesting and unusual geometry for aesthetic or functional purposes.

• 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.

• Rhino has very limited sheet layout tools.
• Grasshopper could be better integrated into the main interface.
• Lack of backwards file compatibility can be frustrating.

A majority of the support for Rhinoceros 3D does not come from the company itself, but from online forums and boards where other Rhinoceros 3D users outline their issues and solutions. The Rhinoceros 3D website does not offer much in-depth support and just outlines general how to's. At the same time, online forums allow for more specific issues to be addressed and solved by the Rhinoceros 3D community.

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.

Rhino is a generic platform. For BIM, you can combine it with Revit or ARCHICAD or look for extensions, such as VisualArq or the GeometyGym extensions for Grasshopper. Due to its good interoperability, I often use it for reviewing AutoCAD drawings or converting 3D models. That said, the most efficient and fast mesh modeling for non-organic geometry is still SketchUp, due to its many smart approaches to automatic mesh cleanup.

• It speeds up projects by streamlining the CAD-to-3D-printing workflow
• As an advanced user, I have written a few tutorials about it as well

• Personally a lot of really cool designs have made it into the real world thanks to my good friend Rhino. Being in the architecture, the ROI is elevated design through giving talented designers the right tool to pull it off.
