That way you can see them in blender and in this case you would probably have to load/import the x3d file and check the results as well.

Go to Editing mode and open up the mesh editing buttons panel.
In the Mesh Tools More section there's a button labeled "Draw normals". Make sure it's selected/active.
The normals should point out from the "solid material area".

I use it all the time to make sure that the model won't spaz out when/if I add the SubSurf modifier.
(If you see a face normal where there should just be a face edge you have a face that is not visible to the eye but it effects the subsurf division quite clearly.. a common problem when a noob like me tries to extrude a face/edge and forgets to move it away from its original location)

The "Draw Vnormals" button does the same for the vertice normals, which may or may not be useful... ]]> Tommy_2Tall 2009-09-24T21:03:53-00:00 Re: Non Manifold... but no non-manifold found in Blender http://www.shapeways.com/forum/index.php?t=rview&goto=6807&th=1406#msg_6807
With some meshes, the option "Recalculate Outside Normals" cleans up these flipped faces.

Select the mesh, [tab] to enter Edit mode. Click the "Mesh" menu on the 3D viewport, then Normals -> Recalculate Outside.

Doesn't work for all meshes, but manifold meshes should work most of the time.]]> clintbellanger 2009-09-24T23:25:27-00:00
