[Chimera-users] Paper viruses

Hi David,
Increasing the Radius in the Flatten Icosahedron dialog decreases the “overhang.”

However, if I understand correctly, it may be best to keep a little overhang instead of excessive empty space.  Squinting at the images Tom Goddard made, it appears the surfaces do extend beyond the triangles.  There is some discussion in the link above as to how you might want to tile the flattened image in a separate application such as GIMP, so that the surfaces on the paper model wrap around in all of the places that they should.

I hope this helps,
