Announcements / Forum moving to meshmixerforum.com
« on: December 09, 2016, 03:52:57 PM »
Hi Everyone, just a note - at some point in the near future meshmixer.com is going to move to a different server, that cannot host this forum. So, the domain name meshmixerforum.com will point here, and already works today.

So, please use that!

cheers -RMS

Announcements / my hardest post
« on: October 12, 2016, 09:23:51 AM »
Hello MM forumites, it is with great sadness that I must tell you that I am no longer an employee of Autodesk. Because of this, I am also no longer able to continue developing Meshmixer.

I left Meshmixer in capable hands, of people who see it's value and do not want it to disappear. I don't know exactly what they are going to do with Meshmixer in the future, and it is out of my hands. As some of you might have noticed, aspects of Meshmixer have made their way into Autodesk Fusion 360, which remains free for students, educators, schools, hobbyists, and small startups.

I released the first version of Meshmixer in 2009. The past 7 years have been an amazing journey, in large part due to the members of this forum. Many features and tools in Meshmixer came as a direct result of discussions we have had here. Today, Meshmixer has been downloaded over a million times, and is used every day by thousands of people across the world, from elementary students to doctors who literally use it to save lives. This would never have happened without your support.

I want to be 100% clear, leaving Autodesk and Meshmixer was my decision. I took Meshmixer as far as I could take it. It is time for me to do something new. I think you will like it!

This forum will continue to exist for the foreseeable future, although the domain may change to http://meshmixerforum.com/. I will not really be able to keep up with the posts here, I will be very busy on my new project. But you can reach me on twitter @rms80 or my personal website http://www.rms80.com.

Thanks for everything!!

Beta / beta 3.1.148
« on: September 16, 2016, 10:57:58 AM »
we have posted a new update, 3.1.148 http://meshmixer.com/beta.html. This version does not have any significant feature additions, the main change is that we switched from Qt 4  (which is unsupported on all major OSs) to Qt5. I know it doesn't sound very exciting but it was a major change behind-the-scenes, that will improve stability going forward.

In particular this should resolve many OSX platform bugs, however it may introduce other issues. We have not done extensive testing, we are hoping you can help with that.

Unfortunately as part of this we had to drop support for 32-bit Windows, at least temporarily. Hoping to bring that back once we work out all the kinks.

Also, you might notice that the download on OSX has gotten enormous (250mb!!). We are currently including /all/ of Qt, not just what we are actually using - this will get sorted out in time.

- added read/write support for 3MF file format, with colors and uv-mapped textures
- new simplified Print UI/workflow
- new Send To Print Studio button for supported printers
- improvements to Optimize Mesh tool
- changed 123D auto-login to be deferred until accessing 123D. This removes startup delays and occaisional startup white-screen hangs.

Beta / beta 3.1.88
« on: March 19, 2016, 06:02:59 PM »
http://www.meshmixer.com/beta.html

- Experimental support structures for metal DMLM/DMLS printing. Use the DMLS Tool Steel Preset in the Overhangs Tool. This is a slight modification on the method demonstrated in our AU 2015 Demo Reel. Support posts are constrained to be in rows, for easier removal (may also be useful for plastic).

- added Segment Jitter setting to Support generator. This option slightly randomizes the posts, so that there are not duplicate triangles/vertices in exported STLs. The results are more likely to import/Boolean cleanly in other software.

- revamped the Advaced Support properties panel (replaced sliders with edit boxes)

- added ability to save support structure generation settings in Overhangs tool as custom Presets. Use Save Current... item at the bottom of the menu. Presets are saved as XML filse in ~\Documents\meshmixer\printers\supportPresets. To delete a preset, you must delete it from this directory.

- many API updates (use current_beta branch)

Beta / Beta 3.1.16
« on: February 03, 2016, 11:46:58 AM »
- restored Replace property panel
- bugfix for cylinder frame in Fit Primitive
- added Height Field mode to Fit Primitive
- added resolution control to Fit Primitive
- added experimental Optimize Mesh tool. This tool tries to shift around the vertices so that upper and lower bounds on the internal triangle angles are enforced. This is important for finite-element simulations, as high-aspect-ratio triangles in the input surface mesh lead to problems in the volumetric tetrahedral mesh.

Announcements / Meshmixer 3.0
« on: January 28, 2016, 01:59:14 PM »
Well, this is a bit late but I wanted to get the first Beta up before I mentioned it. We released Meshmixer 3.0 last week. You can get it on the download page: http://meshmixer.com/download.html.

We also made a video of some of the major improvements, watch it here

The new feature list is pretty extensive, but before I get into that, I just want to point out that we are also now releasing Betas (ie development builds) of our next release. We will be posting Betas regularly, hopefully once a week. This will include bugfixes and new features. Right now I particularly want to focus on UI improvements, so if you have ideas for small improvements, please post them. You can get the betas here: http://meshmixer.com/beta.html, and there is a new forum for discussing the Betas.

OK, new features:

- new Complex objects that contain internal partitions (beta!). Complexes make it easy to design for multi-material 3D printing. A Complex is a single mesh with internal "sheets" of triangles. So, the mesh is non-manifold, but this means it can be automatically split into sub-solids, with the sheets being the interfaces between parts. Some of the tools still work on Complexes (Remesh, Reduce, Volume Brush, etc), so you can edit them once they are created.

To make a complex, you use the new Generate Complex tool. This tool works off of Face Groups, basically you can select facegroups to either extrude-inwards or create an internal fill surface for the facegroup border. Then you can use Split Complex to decompose it into shells (or alternately have this happen automatically on Export, there is a new file mode when Exporting a Complex).

The new Align to Target tool allows you to automatically align meshes in 3D. First you have to set the object you want to align-to as the Target object. Then select part of the object you want to align and run the tool. The alignment solve is iterative, so you can update it multiple times to improve the result. Note that the Alignment can get "stuck", if this happens, try using Transform to get your object closer "in the ballpark" of the alignment you are hoping for.

New Unwrap tool flattens either components or facegroups. This is mainly useful if you want to export to a laser cutter or 2D printer. More to come on this.

To export those flat patches, we added the Export SVG tool, under the File menu. This tool can export various things. For flat patches you would export boundaries, but you can also export the mesh wireframe and colored polygons, including in a 3D projection. This could be useful for making logos and other 2D graphics.

The Mesh Query tool (under Analysis) is mainly for interrogating the mesh. There isn't a lot of immediate use for this in Meshmixer, unless you really care about mesh quality. But if you are using the API, you can use this tool to get things like group IDs.

In the Units/Dimensions tool, we have a new workflow to setting the scene size. You can left-drag to draw linear dimensions on the model, then set the target length of these dimensions. See the video above for a demo.

There are also a bunch of smaller improvements:

- new Select Intersecting action in Select tool (double-click on other scene objects. Note that you need to hide the other object to see anything, as only fully-contained triangles are selected.)
- new Preserve Group Borders and Project To Target options in Smooth Boundary
- Remesh can now automatically preserve sharp edges (awesome!!)
- Make Pattern can now clip to active Target object (this allows for creating patterns on sub-regions of objects)
- Make Solid updates and new mode to automatically preserve sharp edges (this is pretty slow, but it works very well!)
- huge Booleans stability improvements
- minor improvements to Transform, Smooth, Replace and Reduce
- export support for SMESH format
- Pivot-drag positioning shortcut can now terminate on any surface in scene
- new unlit-texture shader
- support for Autodesk Screencast (see screencast.autodesk.com)
- crazy bugfixes
- tons of UI improvements to indicate disabled/unavailable menus and settings
- lots of scripting API improvements (see https://github.com/meshmixer/mm-api)

Have fun!!

Linux / meshmixer for linux 2.9
« on: July 09, 2015, 11:35:44 AM »
I have posted the .deb of meshmixer 2.9 on the linux download page: http://www.meshmixer.com/linux.html
We have actually had this live on the server for a while, so if you happened to do an apt update, you might have already downloaded 2.9

This version has the same functionality as meshmixer 2.9 for Win/OSX. Many bugs have been fixed. We did just release mm 2.9.1 for Win/OSX, possibly that update will come soon.

Unfortunately this is still for 14.04, we have not managed to update it for more recent versions of Ubuntu. However we did make some improvements:
1) meshmixer now automatically sets up your <home_dir>/meshmixer/ folder on startup, so it is not necessary to manually install the documents folder
2) we (hopefully) made many of the .deb improvements that were posted by users in the forum.

We have not done a lot of testing of this, so please if you have any problems, or suggestions, post them in this thread.
