AutoCAD LT vs. Autodesk MeshMixer

It is suitable for use with students who are familiar with using a computer. Unfortunately, we still have many people without access and basic knowledge, such as a simple application of the oficce package.

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.

• Drafting and layouts generation
• 2D Modeling and measurements
• Layers and property features
• Useful commands like mirror, copy, move, array, offset and rotate etc.
• File recovery feature

• 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.

• Incremental savings (if possible) because autosave on big drawings took time to get done because it saves the whole file
• Some custom macros that I made should be made standard (like infinite horizontal or vertical lines)

• 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.

For being a light version of the program it has a ton of functionality and features. I found the system fairly easy to learn how to use once I took an intro course on it. Overall i think the usability is great and it was easy to jump right in and get working in the program

Although AutoCAD LT is the lite software when compared to standard AutoCAD, it does all the work when it comes to 2D modeling and issuing design drawings. When comparing it to BricsCAD, AutoCAD LT shines, as it works without freezing and is usually more responsive than BricsCAD, it just outclasses it.

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.

• We have been able to looks at CAD files that ordinarily we would not have been able to open. Giving us more control over our projects
• We are now able to create very accurate draft designs that save us and our engineering/architecture team valuable time in drafting.
• We can create our own plan sheets for when it is something that does not require a stamp. This saves us time and money.

• 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
