Questions & Troubleshooting / Re: Supports generated inside objects
« on: July 13, 2014, 07:34:37 PM »
One way to automatically separate the support structure is to use the 'Convert to Solid' button in the Overhangs tool, after you have generated support, and in the popup select 'New Object'. This will create another support mesh that is a separate object, so you can hide the original mesh and delete any internal bits.

Note that the original support structure will also be kept - You will have to go back into the Overhangs tool on the original mesh, and do a Remove All Supports.

Many of the internal support posts are due to some bugs which we have mostly sorted out. So, improvements will be coming.

excellent questions! Please give me a bit of time to find some answers (I do not work on the 3DP view directly)

Thanks for the reports. I will look into it.

Bug Reports / Re: Supports not generated

Well, the first problem is that your object is 2.5mm high. So, it is too small - the default support post is 2mm wide, so none will fit! Use the Units/Scale tool to make it larger.

The mesh itself is kind of the worst case for meshmixer - all long skinny triangles. So, if you feel like the support is not as good as you would like, try using the Make Solid tool to create a version with better triangles.

Yes, sorry, we do not support 10.6 anymore, due to Apple no longer supporting it in XCode. You will have to try out an older version (I think 2.0 works on 10.6, otherwise you will have to go back to the release just before that). You can get old versions here:

(scroll down to the Release Notes, there are links for each version)

Wish List / Re: Rectangular Support Structure

if you expand the 'Advanced' tab, you can turn down the 'Post Sides' slider and you will get fewer triangles.

Otherwise, unfortunately there is not much that can be done in the current build. We should have some improvements in triangle count in the next update.

Questions & Troubleshooting / Re: using the warp tool
« on: June 24, 2014, 10:26:35 AM »
This is happening because there are some degenerate triangles in your mesh (ie triangles with near-zero area). You can usually clear this up by doing a Remesh on the area you want to Warp (or perhaps just a tiny bit of Reduce, if Remesh is going to ruin important details).

I would appreciate if you could send me the file (meshmixer at, then I can test to see if I can handle the errors.

Bug Reports / Re: Severe crash

If this happens to you again, it would be great if you could generate a log file with the crashing version. I cannot seem to reproduce this problem - your INI file works fine for me, so it is some combination of the INI file and something on your local system.

My guess right now is that the autosave file itself was corrupted, and that somehow the loading was getting stuck. By deleting the INI, you clear the autosave info, which would clear up the problems.

That is not a use-case I imagined...I will look into adding a no-refinement mode.

I'm not sure why the brush doesn't work w/o refinement, either.

Your best option would be try actually try meshmixer on these two systems. It doesn't perform vastly differently with different OpenGL cards, and new laptops should all have sufficient OpenGL capability.

Older Intel cards are very problematic for meshmixer, they often result in it being kicked back to "basic" rendering mode, which does perform significantly worse. However, my macbook air has an Intel HD3000 and runs meshmixer just fine. So, I can't imagine an Intel HD4400 being a problem itself, as long as you can install recent drivers.

Bug Reports / Re: Crashed and wont open files anymore

most likely your INI file has been corrupted. Try this:

If that doesn't work, please come back for more help (sorry for the delay in replying)

Questions & Troubleshooting / Re: connecting inner and outer shells
« on: June 13, 2014, 08:08:47 PM »
the Offset tool can only offset so far before things self-collide, and it doesn't resolve those issues. If you want to create an inner shell for this model, you probably will get better results using the Make Solid tool, with the mode set to Accurate and the Offset Distance set to -4mm.

Questions & Troubleshooting / Re: Mesh won't slice
« on: June 13, 2014, 08:06:21 PM »
Unfortunately MakerWare seems to have random issues with certain files. I have had much simpler models which would cause MakerWare to hang. Sometimes remeshing will help (but sometimes not)

So in the last image you have just pushed the tops of the posts up into the model a very small amount, yes? Just want to make sure I am seeing it correctly.

under the Edits menu you will find a Make Pattern tool. You can use this to do various patterning things (although the closest thing we have to a hexagonal honeycomb right now is a hexagonal tiling of cylinders). But there is no video for this tool will have to experiment.
