I have looked at this post a bunch of times and still do not entirely understand how you did that. It looks awesome, though!

Questions & Troubleshooting / Re: Not documented keyboard shortcuts?
« on: April 23, 2014, 07:04:39 PM »

Are you using 32- or 64- bit versions? I can try to help with hotkeys, but I would also love to be able to fix this problem with the pop-up menus, if you are willing to help. The menus/etc should not depend at all on the graphics card, but it is a bug we haven't been able to fix because we cannot reproduce it only any computer.

Can you email, so we can communicate directly? We would need to send you a build with more debugging output, that could try to help us track down the problem.

Questions & Troubleshooting / Re: Plane cut/snapping
« on: April 23, 2014, 06:59:55 PM »
When you are rotating, a circle of tics will appear (it is quite faint). Drag your mouse over the ticks, and it will snap to them, allowing you to hit exact degrees.

Immediately after you do a plane cut, you can run the Align tool and it will use the cut plane as the alignment source. You can change the X/Y/Z axis as the alignment target in the properties, and use the big blue arrow in-scene to flip the alignment direction.

You can also use the Align tool at any time, to orient the model. Just left-click on the face you want to align with the X/Y/Z plane.

Wish List / Re: Autosave directory

your IT folks should have a way to deploy the .ini file to every user profile. You should just have to do it once on one computer, to make the initial .ini file. Then you can give them the .ini file and the path that it should go into, in the profile (ie \Roaming\Autodesk), and they should be able to copy it to all user profiles (because the profiles are actually stored on the account server, not on each computer).

If the above is not possible, another option would be to create the initial .ini file and make a .bat file that copies it to the right place. Then each user just has to run the .bat file once. The file should be copied to be C:\Users\%USERNAME%\AppData\Roaming\Autodesk\

Here is one way, perhaps MagWeb will come up with something easier =)

1) create a panel roughly the shape of where you want the honeycomb, that is thicker than whatever you want the honeycomb in. A good way to do this is to import a Plane, Select the relevant area on it, Smooth Boundary, delete the rest, and then Extrude it.
2) run Make Pattern on that. Use the default Tubes pattern. You might need to rotate the 3D gizmo 90 degrees, so that the tubes are going through the panel. This will create a honeycomb of holes
3) uncheck Clip To Surface, turn up the grid/mesh resolution a little bit, and set Reduce to 0. Then Update and Accept. This will create a bunch of little tubes that you are going to subtract from your object.
4) (optional) Add some resolution to the area you want to modify, so that the triangle size is in the ballpark of what the triangle size on the tubes is
5) select object, then shift-click on the tubes object, and run the Boolean Subtraction under Edits.
6) Wait a long time (depending on # of holes)
7) done! run Inspector to make sure there are no little glitches

If (6) fails, add more resolution to the area you want to modify. If the object you are subtracting from is very thin, this might not work, unless you add a ton of triangles. This video might help you debug problems.

Questions & Troubleshooting / Re: Crashing on Transform and Overhangs

The issue is probably due to WinXP combined with your embedded graphics card. That type of Intel GPU was never very capable, and most likely they are not producing updated graphics card drivers anymore for WinXP. Somehow these things are combining to cause crashes in different tools, probably depending on the particulars of what the tool does. I tried the win32 version on Win7 and it worked without any problems in the cases you are describing, so it is very hard for us to debug (we do not have WinXP development machines anymore).

Unfortunately now that WinXP is unsupported by Microsoft, the reality is that most applications are probably going to stop working in short order, because the new software development tools will not support XP. In Visual Studio 2012 (which is what we are using now), we could still turn on WinXP support, but it was disabled by default. And I expect that VS 2014 or 2015 will not have that capability anymore =\

Yes, this is probably the best way to do it. Hopefully your students can edit the .ini file. Since it is in the Roaming profile, it should move with them from machine to machine...

This does mean that any parts they create will only be on the local machine. We do not have a way to separate autosave and parts folders yet.

in the print view, click on the printer name to open the pop-out. Then at the bottom there is a button Add/Edit Printers.
Once you open that, click Add New in the bottom-right corner.

Thanks MagWeb. Drop Solid is a bit rough, I was travelling the week before the release and so I wasn't able to give it any polish. I will definitely have to think about how to handle dropping off-grid...the main question is just how to make it clear to the user what will/has happened.

Are you using the most recent graphics drivers for your machine? (what is the graphics card?)

If you are not sure, following this process to get to the log file would help:

Can you post the Yoda STL, and the other one? That is the quickest way to debug. Have you tried these things on the built-in bunny model?

This should be fixed in 2.3. Please let me know if you find any more filename problems.

Make Slices is a bit slow, we will improve that in the future. But in the meantime, it is a great way to cut up an object into smaller pieces, for example if you want to print something huge in multiple prints. Here is a simple workflow:

1) Make Slices with Stacked3D mode to slice along Z axis (set thickness to print bed size, minus some tolerance)
2) select new objects in object browser and Combine
3) Make Slices along Y axis
4) Select new objects in object browser and Combine
5) Make Slices along X axis
6) Select new objects in object browser and Combine
7) Select final object and do Separate Shells

Unfortunately sometimes you will get errors doing the above. Sorry, we are working on it! The workaround I have found is to operate on pieces that are separated in is when the parts have adjacent cut faces that you may have trouble. So after the Combine, you can selectively disconnect areas by selecting bits of them and then hitting 'e' to expand-to-connected, and doing a Separate. Then Make Slices on that piece.

Using this workflow you can tweak which parts get cut, to avoid creating very thin regions or tiny bits, which will be inconvenient to print. You do not have to cut on a grid, you can put the cuts at arbitrary locations. You can even do cuts at angles by rotating the object!

Sorry, they shipped it yesterday but it was a holiday in Canada =)

release notes:

Announcements / meshmixer 2.3
« on: April 22, 2014, 08:43:11 AM »
Out yesterday! The focus on this update was to add custom printer support, but we also added a few new tools:

•   Add/Edit custom printers, so you can prep your 3D prints for any 3D printer
•   New Make Slices tool: Slice an object into a number flat slices. Two techniques: Stacked or Stacked3D
•   New drag/drop solid objects in addition to parts.
•   Added part categories to the Meshmix panel to accommodate growing libraries of parts and solids
•   New Separate Shells tool to separate meshes into disconnected components
•   PLY binary format support
•   (limited) 3D Connexion spacemouse support
•   Better naming of newly created objects from duplicate, separate, etc…
•   Lots of bug-fixes and stability improvements   (for example, unicode filenames work again)
