[Chimera-users] Export Scene, Mesh Surface, wrl

Hi Cynthia,

  I made a surface, showed it as mesh, used File / Export Scene… choosing VRML output, then read the VRML file back into Chimera and it displayed it correctly.  So the file does contain the mesh.  It is probably a Cinema4d issue not a Chimera issue causing your problem.
