OK, my cute little experiment has now become a thorn in my side. I've got a model of a steel framed building that I would like printed. The original software is an architectural program (Revit) which will export to stl but it's really intended to create building plans not plastic models. I can fatten up my wall thickness to some degree in Revit but now I'm also seeing a "non fixable 800 shells" error. Before Mesh Medic was introduced, I could not even upload the whole model. The building walls and foundations were non-manifold even though they were solids to Revit. With Mesh Medic, I can at least upload the model but it does not pass further tests and is canceled.

Can the shell problem be easily addressed with Blender? I'm not to keen on learning blender for the sake of this experiment.

Thanks.]]> phoulx 2010-03-23T02:37:41-00:00 Re: Too thin, too many shells- Revit>stl>blender>here http://www.shapeways.com/forum/index.php?t=rview&goto=11048&th=2235#msg_11048 Then we can see how bad (or not) the problem is!

Blender is hard to get started with, but it very soon becomes productive. You can get the basics by running through a few simple tutorials.

There are quite a few blender users on this forum. I'm sure most will give you help if you get stuck.

The STL imported into Blender, and needed a 'Remove Doubles' to join duplicate vertices.

You have LOTS of extra internal faces, just about every join in a wall would need fixing.

As an example, the section highlighted in this picture has 6 extra faces.

index.php?t=getfile&id=3052&private=0

Once you select the faces and delete them the model seems mostly manifold. But there are so many of these, you will be there some time!

I don't know if MeshLab or AccuTrans will be of any help in removing these extra faces?
