"Curve From Mesh/Text" not working on wireframe of cube I was following this link on solidifying edges. When I went to convert the mesh to a curve, nothing happened. Here's what I starting with a new file:


Select cube
Tab to edit mode
Ctrl + F > Wireframe
Tab back to object mode
Alt + C > Curve from Mesh/Text


Nothing happens. I noticed that it works if I add a Grid or Circle and try to convert those. What am I doing wrong?

I have Blender 2.71 (Release Candidate). I also tried converted the cube directly without converting it to a wireframe, but that didn't work either.

Context: I'm trying to create a picture like this, with shadeless faces (that occlude the background) and dark edges:
Conversion to wireframe does this in essence, for every face on a Mesh.



The wireframe conversion transforms each face into thin faces interior to  the perimeter of the face, this function has parameters that you can change to adjust the width of those faces, but by default it is rather thin.


  As a side note: The Curve from Mesh/Text conversion tool operates best on Meshes if you remove the faces first. (X, remove only faces). If the mesh doesn't have any Faces there is no need to convert to wire-frame (or remove doubles later on).


You can set the thickness of the wireframe to 0.000, and then you'll see little dots on the edges, because it still creates faces but they are so thin they will fall below the 'remove doubles' limit:



Removing doubles would look like this:



At this point you can convert to Curve from Mesh/Text. But I doubt that is actually what you want.



If you follow the link in the first comment on your Question you will be able to render results like this:



Conversion to wire-frame isn't the way to go about rendering with face occlusion.
