Have you tried the Hollow tool? It is under the Edit button on the left.

Questions & Troubleshooting / Re: Export obj textured issues
« on: Today at 09:16:46 PM »
We have had one user report a bug where the textures are being saved with the wrong filename in the .MTL file. It is just a text file, so you can open it to check. If it has a full path (ie C:\\...) then that is probably the issue - just delete the path and change the extension to .png and save the file.

If that doesn't fix it, then you have a different bug and we will need more details.

2.5 didn't have this issue, and it will be fixed in the next release.

Questions & Troubleshooting / Re: Measure tool in V10?
« on: Today at 09:14:42 PM »
Actually, many artists find things like axes and grids very distracting. Meshmixer started out as a 3D-sculpting tool, and in that domain such in-scene visual artifacts are usually not present.

As it has evolved more analytical capabilities, we have added a few things, like the ground-plane grid and origin point. You might note that the transform gizmo has red/green/blue arrows which correspond to the unit axes when in world-coordinate mode.

However, even there we have a problem because some people expect Z/blue to be up, while others expect Y/green to be up (which is the case in meshmixer). There is about a 50/50 split on this between different modeling tools/domains. Also, assuming that color is a good differentiator is great until you get an email from a colorblind user =)

(not saying that it wouldn't be nice to have an option...it is on the long list!)

Questions & Troubleshooting / Re: Measure tool in V10?

Hi Frank, to get a point-to-point measurement you need to change the Type to the one in the bottom-left of the flyout, that has two circles and a blue line with dots on either end. The Direction setting will be ignored for this type of measurement.

You are right, it is not really possible to know which are the X and Z axes (Y is up). If you have the grid on, it will show you the two directions, but you will have to check both to find out which is X.

Since it doesn't exist in any documentation, I will just explain the other Types:
First row, left-to-right
   - interior measurement from left-click-point to first ray intersection (ie ray goes into surface)
   - exterior measurement from left-click-point to first ray intersection (ray goes out from surface)
   - interior measurement from left-click-point to last ray interesection (ray into)
   - exterior measurement from left-click-point to last ray intersection (ray out from)
second row
   -  point-to-point (left-click to right-click points. In 123D navigation mode, use ctrl-click/cmd-click instead of right-click)
   -  absolute 3D coordinate measurement
   -  cylinder measurement (this is pretty flaky...but draw with left mouse to drop sample points, and eventually it will fit a cylinder and show you the radius)

For the modes above that mention a ray-cast (ie the top row), the Direction field defines if the ray direction is the Surface Normal, or one of the X/Y/Z axes.

The three numbers on the right are the Current measurement under the cursor (middle, black), the Maximum value measured during a click-drag operation (top, grey) and the Minimum value (bottom, grey). This range is useful if you are taking measurements from scan data, where (for example) thickness will vary over an area.

Right, sorry. In 123D mode right click has different behavior, and the docs were not updated. My mistake (I never use 123D mode!)

You can access the right-click functionality by ctrl-clicking instead (or possibly apple-key-clicking...on windows it is ctrl-clicking)

The right-click works for me (on windows). What platform are you using? Does the ball turn white when you hold down the right click over it?

What are you expecting to happen? Right-click just selects the defect with the Selection tool, so (for example) on the bunny you will see a little bit of orange around the edge, and the Tool will switch to selection.

Questions & Troubleshooting / Re: Optimize orientation?
« on: October 21, 2014, 08:57:36 AM »
The Optimize Orientation button tries to find an orientation of the model that will minimize the *volume* that requires support. (ur current version over-estimates the volume somewhat, which complicates things further).

For the bunny model, depending on your overhang settings, the minimal-support-volume orientation is not necessary the orientation where the flat base is on the bottom, because the *volume* underneath the ears goes all the way to the ground plane (and hence is quite large). You can see this by running the Orientation tool under analysis. The default settings (Support Vol Weight=100) are similar to the Optimize Orientation button in the print view. You should see a set of arrows in the scene, with little bar-graphs beside them. The green bar shows the support volume measurement, and it is smallest when the bunny's nose is on the ground. The flat-base on the ground is another one of the arrow options, and you can see that the green bar is slightly taller.

The orientation optimization doesn't know about "printability", and it doesn't know about our meshmixer support-structures (the branching trees). That would be too slow to compute in the optimization. So the volume measurement is a heuristic that lets us do something reasonable, quickly. However there are cases where it is not as useful, and large-flat-base objects are one of those cases.

However for those objects you can easily put the flat base on the ground yourself =)

Questions & Troubleshooting / Re: OS X Yosemite
« on: October 21, 2014, 08:49:47 AM »
Sorry, I don't think meshmixer has any dependencies on the operating system. Which Tool in meshmixer are you having trouble with? I will try to find someone who has a Yosemite machine, to try to reproduce your issue.

Announcements / Re: meshmixer 2.6
« on: October 20, 2014, 10:42:03 AM »
Ugh. For scale we cannot easily transform an current-scaling from one frame to the other. So this is the intended behavior (the second thing you mention). But I agree it is not very nice...

Does this still happen in mm 2.6? (sorry loaned out my mac laptop, can't test myself...)

Well, I was actually hoping that unplugging the network would make it happen all the time! But still a useful finding.

Can you try with network plugged in, but un-check the two boxes at the bottom of the About box (check updates automatically and approve usage data collection?)
And/or check/uncheck them individually?

My guess is that these checks sometimes get stuck waiting for a remote server to respond...which would explain random nature

Questions & Troubleshooting / Re: Unable to create hole when hollowing
« on: October 17, 2014, 10:54:10 AM »
Your original mesh does not have nearly enough triangles to do this. Meshmixer booleans require comparable mesh density on both objects. Your hole has *tiny* triangles and your outer face only has a few huge ones, so it will not work.

Also, 103 is far too low a solid accuracy, and 128 doesn't really give you enough triangles on the hollow surface either (Also I noticed at this resolution that the hollow pokes-through in a few places). Because you want a 1mm wall, you need to go higher for that reason as well.

Attached is a .mix file where I have remeshed some of the outer faces. Hopefully one of these is where you want to put your hole. I used 256/256 for accuracy/density, and a 1mm hole worked for me.

Can you try turning off your network connection and see if this happens consistently?

Which printer are you trying to print to? What is the text on the button?
