Questions & Troubleshooting / Printing options
« Last post by Darque1 on April 27, 2017, 04:40:50 AM »
Hi All,
In older versions of Meshmixer you could go into the print area in the tool bar on the left and you could then thicken walls, add supports etc. In the latest version if I go in there all I can do is select a printer and a material and then export - no repair options etc appear. If any one can point me to how to thicken the walls of a model in the new version I would much appreciate it. thanks

Announcements / Export multiple objects and print setup changes
« Last post by Cuba on April 26, 2017, 04:50:50 PM »
Hi, Meshmixer used to export all the separate parts in an object as individual Stl files plus  a combined Stl file. This function seems to have recently disappeared in the latest update and when you export everything is combined to one Stl, do I need to set a preference to achieve multiple stls?
The whole print setup looks different where you used to be able to access Shapeways and materials, or re scale and repair, these options have now all gone. I hope someone can advise that these functions are still alive somewhere as they make Meshmixer an excellent tool. Cheers

Merci M. Brochu,

  I will certainly try this quartet library.
I also have access to some AutoDesk professionnal products, could AutoCad or  Inventor help me?

General Discussion / Creating A Shader
« Last post by TheRedGuy90 on April 25, 2017, 05:39:46 PM »
I can't find a tutorial on how to make a fitting shader for my mesh.

I have a Drawing I turned into a .obj mesh from Photoshop, saved the drawing itself to a transparent .png, but importing that .png as a shader does not fit the mesh when imported into Meshmixer.

Hi,

Unfortunately Make Solid does not produce a tetrahedral mesh. It only closes open boundaries (i.e. produces a closed, manifold mesh which can be interpreted as representing a solid volume, hence the name "Make Solid").

If you're comfortable compiling C++ code and don't care about adaptive tet sizing, I recommend the quartet library (https://github.com/crawforddoran/quartet). It has a permissive license and is pretty straightforward to use.

Questions & Troubleshooting / How to export a Solid.
« Last post by placasse on April 20, 2017, 06:29:50 PM »
Hi,

  I need to convert an stl (list of triangles) file into a solid mesh (list of tetrahedra) suitable for finite element methods.
I would be happy with any human-readable file format.
I tryed many softwares (not all of them yet) and MeshMixer is the first one I found that can build such a mesh (Edit->Make Solid) with my huge and complicate file.

The result looks good, now I need it outside of MeshMixer.
I tested all the export but I can't see any tetrahedra in the resulting file, did I missed something?

thanks

Scripting / API Help / Re: Ignore pop up dialogs when scripting Meshmixer
« Last post by tkmorrison on April 20, 2017, 03:15:13 PM »
My number 1 requests would also be that popups be suppressed. It makes automation quite difficult. I resorted to using scripted key-presses, and it's pretty messy. (On windows + python I'm using win32com.client )

Three popups have been a problem with version 3.2:
1. The complex object / nonmanifold popup when exporting a mesh.
2. The 'meshmixer crashed' popup when starting meshmixer after a crash
3. And then crashes themselves, but I think the popup here is a windows popup.

@bathsheba - In python you can at least close MeshMixer without inducing a 'crashed' response using this:
meshmixerProcess = subprocess.Popen( ["C:/Program Files/Autodesk/Meshmixer/meshmixer.exe"] )
meshmixerProcess.terminate()

You can use this to convert the tris to quads:  https://github.com/wjakob/instant-meshes

Fusion can work with a medium level of quads...what you can do is do this conversion with a lower number of quads, import both the quads as well as the STL into Fusion.  Convert the quads to T-splines in Fusion, and then use the subdivide/pull command to add in more detail where you need it, and less detail where you don't.

If the quads conversion is OK already, then you're done, but the segmented workflow above is longer to do, but required for more complex models.
