[Chimera-users] 3D printing a viral capsid

Hi Jeremiah,

  I have fixed the Chimera export STL bug that caused your multiscale virus capsid model to produce STL that did not contain the whole virus.  The fix will be in tonight’s daily build, dated August 23 (or later) on the Chimera download page.  The bug was that copies of identical surfaces representing proteins were not having their individual position and rotation applied.  Thanks for reporting the problem.
