The undocumented command polySelectSp works for me in that situation, it also returns verts and not edges. The verts still aren't ordered so you would have to solve that from the return list using something like Ted's method.
import pymel.core as pm sph = pm.polySphere()[0] pm.select(pm.polySelectSp( '%s.vtx[%d]' % (sph, 260),'%s.vtx[%d]' % (sph, 274) , q=True, loop=True )) On Tuesday, October 23, 2012 12:26:45 PM UTC-7, charles le guen wrote: > > create a default polySphere in a new scene and run these two lines: > > > import pymel.core as pm > > pm.polySelect( 'pSphere1', shortestEdgePath=(274, 260) ) > > > > You'll see shortestEdgePath finds a route that isn't a straight line > between the two verts. > > > > > > > > On Tue, Oct 23, 2012 at 3:10 PM, Jesse Capper > <[email protected]<javascript:> > > wrote: > >> How is the calculation of shortestEdgePath flawed?
