Bug Reports / Re: crash at loading files
« on: January 30, 2015, 03:13:45 PM »
Sorry, the meshmixer forum is not an official autodesk forum - I'm really the only one who provides support here on a regular basis. As you note, because it is free, we do not have a dedicated support team. Sorry!

One thing you could try is un-checking 'Approve collection of usage data' in the About box (Help -> About). That resolves these problems for some people.

If that doesn't fix it, then the problem may be that your graphics drivers are not working with our GPU shaders. Unfortunately there is not much we can do about that - a 2009 iMac has very old GPU hardware and we cannot possibly test all modern GPUs, let alone hardware going back that far. In this case there is nothing we can do - sorry again =\

OK, thanks. I will look into it.

This has been on our "todo" list for over a year now...thanks for the nudge =)

The pre-remeshed geometry is just a bunch of overlapping cylinders...are you sure that is what you want? I guess if you are just using it for rendering it makes there something else you would use it for? It is easy to do what you ask, I'm just curious.

Hello everyone - sorry for not replying to your posts, I was busy working on a 3D-printing project

But in the meantime, the rest of the meshmixer team was busy making a big addition - We now support save/load to your 123D Account, directly inside meshmixer.

My guess is that most of you on this forum do not have a 123D account, but there are lots of reasons you might want to consider signing up:

- The free account gives you unlimited cloud storage, so you can save on one computer and open on another, or share with other people. If you are using meshmixer in an educational setting, this is a great way to distribute files to your students.
- If you use 123D Sculpt+ on IPad (which is a great app) you can easily import your files into meshmixer
- You can also load your 123D Catch files directly into meshmixer (if you use Catch you already have a 123D Account, you just have to log in inside meshmixer)

Even if you don't use a 123D Account, you should check out the Gallery, which has a ton of free models to play with. In particular, if you change the sorting from "featured" to "popular", you will find a lot of recognizable models to experiment with. It is a great thing to have available if you are showing meshmixer to someone else (particularly kids!)

I did manage to sneak in a few small improvements:
- you now stay in the selection tool when you do face deletions (this was a forum request)
- we improved SLA support structures, and added a preset for the new Autodesk Ember printer
- support auto-generation now places the result on the print bed
- double-click inside selection tool now does a flood-fill in Vertex Color mode, instead of a select-face-group
- misc small bugfixes

It should be run the orientation optimization you would just need:

mm.begin_tool(remote, "orientation")

of course you would have to write the python code to iterate through the files and open each in sequence. For each file you would do something like:

new_objs = mm.append_objects_from_file(remote, part_filename);
(...optimize orientation...)
mm.delete_objects(remote, new_objs)

Unfortunately the way meshmixer currently works, you either have to install manually for each student, or do some workarounds. What you describe has worked for other people, however you can't just create the folders it mentions. You have to copy the entire <username>/Documents/meshmixer/ folder contents (from *your* home directory, which was created when you ran the installer) to the re-directed path you set (ie E:/meshmixer/)

You mention E:/meshmixer and E:/meshmixer/meshmixer...I'm not sure if that was intentional or a typo. But I am pretty sure you should end up with folders like E:/meshmixer/libraries, E:/meshmixer/printers, etc, instead of E:/meshmixer/meshmixer/libraries

Also you need to have this modified meshmixer.ini for each user (in case that wasn't obvious)

Questions & Troubleshooting / Re: Moving the ground plane
« on: January 07, 2015, 09:26:03 PM »
The ground plane doesn't move, it is always at Y=0. It isn't tilted, you are just looking at it from an angle. It may be that you are in "Free" camera mode, try holding down the spacebar and un-toggling the "Free" button.

Questions & Troubleshooting / Re: My own meshes
« on: January 07, 2015, 09:22:32 PM »
Please run the Units/Dimensions tool to check the physical size of your model. It may be only a few millimeters high, in which case the wall thickness might prevent it from being hollowed.

If it isn't that, then please post the file and I will check it.

could you post a screenshot of your second problem? Not sure I understand...

General Discussion / Re: How much RAM/disk space does Meshmixer need?
« on: January 07, 2015, 08:43:01 PM »
Sorry about the captchas, unfortunately this forum needs to basically run itself, with minimal spam. There is nobody who has the job of  "forum admin"...any time I spend maintaining the forum is time I don't spend improving meshmixer!

Please try disabling “usage data collection”, as described in this thread:

good advice. Unfortunately unstructured high-resolution meshes (ie what you work with in meshmixer) really can't be efficiently compressed in any way, at least not if you want to modify them at interactive rates. So, with meshmixer we trade memory for interactivity.

If you want repair tools that scale to huge meshes, but are less interactive, you could try something like Autodesk Momento But you won't find a lot of the other modeling and 3d-printing capabilities in there.

Bug Reports / Re: Hit "delete key" and loose your work
« on: January 05, 2015, 03:04:17 PM »
Sorry!! You can also use X to discard/delete, and X will *not* delete the last object. A typo allowed the delete key to delete the final object. Will be fixed in next update.

However, you can use these keys to delete all but the last object, that is by design. You can undo these deletes.

I will experiment with keeping you in Selection mode after a delete-faces. That does kind of make sense.

does this happen if you restart? You do have to restart when switching to Basic Rendering.

I cannot reproduce this at is possible that the rendering data structures were corrupted, but if it is happening after a restart...hrm. Does it happen if you move the hidden copy? Which brush are you using?

(Also, does it happen after a reboot? I sometimes have sporadic GPU issues that go away after a reboot, on windows....)
