I've been busy writing a new tutorial on finding and fixing non-manifold areas in your model. Before I publish it 'formally', I'd love to get some feedback on it.

Is there anything that isn't clear enough, or that I forgot to add?

Thanks!

Now, I'm not sure of the mechanics on the Shapeways server, but I assume it's much like importing the resulting .STL and removing duplicate vertices - now we have manifold problems.]]> loonsbury 2009-03-16T17:02:10-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=3390&th=748#msg_3390
Most of our identical vertices, cant be deleted, they are used for different objects.

Is it possible to make a local check with the Shapeway software that checks our model? it is a hell of a job to go true all those steps to upload the model, and then wait to get a mail if it is ok.

I guess the most important ones are these:

TAB - switch from object to edit mode
X - delete selected vertices/edges/faces
F - fill selected polygon

You'll find a full hotkey list here:

@ewco: do you mean integrated into your own 3D app, or as a stand-alone app?

Cheers,

Interestingly enough, if you upload such a model *before* unifying the vertices, our server will accept the model just fine.


Mine haven't worked for that reason in the past, maybe I should try again.

This would save a lot of time and effort, and a bit of network bandwidth, too.]]> tones3-d 2010-01-23T03:36:49-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=28088&th=748#msg_28088
"sube" should be "cube"
"undoubtably" should be "undoubtedly"
"containind" to "contained"
"vizualisation" to "visualization" or "visualisation"
"remodelling" to "remodeling"

On the subject of manifold surfaces, it would be good for you to point at the original tutorial, http://www.shapeways.com/tutorials/things-to-keep-in-mind. In that tutorial, I had a question: you show a Blender operation to make the object non-manifold. What does this operation do? Does it simply move the two touching edges back a bit from each other?

I'm looking forward to unleashing the mesh manipulator MeshLab to clean up my meshes, so I want to understand "manifold" a bit more in other packages.

I dont know if it's a far-fetched idea... but do you think shapeways can negotiate a deal either with the authors of netfabb or magics for a slim down version of their software for this community ?

Shapeways has managed to introduce and expand 3D printing to a vast audiences of hobbyists, students, designers, of all ages and occupation - this market requires a slim version of a "fix-it-all" software to fix stl files - so designers can actually spend their time and focus on designing and not (sometimes) be frustrated with an illusive non manifold error or any other common errors.

Sure, shapeways Meshmedic is a quantum leap vs. what we had to deal with before its installation
still, an affordable-for-all professional software such as those pricey packages is the next big step in my opinion.

everyone wins.

Ctrl+Alt+Shift+M "shows" non-manifold, not "makes" non-manifold. It selects the vertices which are non-manifold in the object currently in edit mode. Note that the command does not deselect everything first, so if you only want non-manifold vertices, you should deselect everything (two taps of the a key will suffice), then use the command.]]> TurtlesAreCool 2011-05-24T03:31:40-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=28096&th=748#msg_28096 stannum 2011-05-24T04:55:13-00:00
