Use the Align tool. Change the mode drop-down to "To Last Plane", and click on one of the faces you want to be on the print bed. use the large semi-transparent blue arrow to flip the object, if it ends up below the plane instead of above.

Questions & Troubleshooting / Re: making groves on top of 3D mesh.

So are you basically saying you want to cut one object with the other, but create new facegroups at the cut borders instead of actually separating it?

Fusion's standard export does not produce a mesh suitable for Editing - it is fine to print directly, but not to edit.

When I export from Fusion I always set the Maximum Edge Length to something small relative to the model size. IE at least 1mm, or smaller if it is a tiny object or has small features. Also set the export quality to High.

Bug Reports / Re: crash at loading files
« on: February 27, 2015, 10:19:48 AM »
We know about this problem, and I agree that it is serious. We have been trying to fix it for several months. It is not entirely under our control - the crash happens inside a third-party library we use, and we cannot fix the problem in the library. We have a possible workaround, to avoid the crash, that should be in our next release. However it is difficult to be certain because this problem is intermittent - for example on my development machine it only happens maybe once out of 20 times I run meshmixer, and on my macbook air it never happens. This makes it extremely hard to fix.

Questions & Troubleshooting / Re: Getting a texure to be PER VERTEX

You need meshlab to bake your .obj textures (ie images and .MTL file) to color-per-vertex. You can export this from meshlab as OBJ, PLY, or WRL.

Genius !!!

Yes, that could be scripted...

It is easier to fix the flipped normals if you use Generate Face Groups first (then you can just double-click to select the flipped regions, with the allow-back-faces checkbox on)

But the non-manifold part at the bottom is trouble. I can repair it in meshmixer but it took a lot of steps...

should be fixed now...for some reason this specific board was set to not allow global moderators to post images.

I would be interested to see your workflow regardless of whether it is what m.najem was looking for. Very curious to see how you managed that in meshmixer (!!)

(I can only imagine doing it with expand-selection, but it wouldn't give such clean lines...)

they may not support OBJ with color-per-vertex. This is not a standard format, and most 3DP manufacturer software does not support it (which often defines what the print service supports).
You could try exporting a .wrl from meshmixer, this stores color-per-vertex and I know several color printers drivers support this one.

General Discussion / Re: Add tube
« on: February 24, 2015, 09:38:25 AM »
Add Tube allows you to create tube-like shapes and either subtract or add them to your model.

There are a few examples in the video for this research paper: http://research.autodesk.com/publications/tubes
But the version in meshmixer has somewhat different capabilities.

It can autoroute complex tubes through an object, but it can also make simpler straight tubes, which basically can be used to create holes through your model.

Bug Reports / Re: Holes make MM crash on Make Hollow accept
« on: February 24, 2015, 09:08:13 AM »
Thanks for reporting. I found one crash bug, which I have fixed, but still there are problems in this particular example.

The holes are created with our Mesh Booleans, which are not perfect. The biggest issue is when the mesh has very different resolutions. So, in the screenshot, the hollow shell has much lower resolution than the outer shell. This causes the Boolean to fail. Although in future it will not crash, it will sometimes still produce the behavior where the hole is not actually added (this is what happens when the boolean fails w/o crashing). To get better results, turn up the resolution for the interior mesh (or reduce the exterior, although that still might not work because the hole cylinders are poking all the way through the object...)

For making holes manually, you might try the Add Tube tool. Use Linear mode, Normal or Y direction. Then you can position & boolean a cylinder in the same way.

Also, how precise do the grooves need to be? IE do they need to be nice crisp cuts, or could they be kind of rough, as long as they were wide enough for your radioactive source (I assume it is a wire or tube or something?)

Hi, I just want to make sure I understand. I can easily make grooves that are a consistent depth, ie so that the thickness underneath the channel is consistent. However they are at a regular spacing when viewed from the top. So, if you were measuring distances along the surface, then the separation would be greater than 1cm.

Is this what you are looking for? Or do you want the separation distance to be 1 cm between pairs of curves when measured along the curves, ie the geodesic distance between the two curves is 1cm?

(Just checking as it seems like you want the latter, but that is much harder! But perhaps still possible =)

Are you using the main Meshmixer view, or the Print view?
