Thanks for the suggestions guys. I can't rely on border edges or not, but I
can't, because you can close a plane (fill hole).
I did find that the nParticle fill mesh, only will generate nParticles if the
mesh is a "solid" mesh with or without holes. After the fill hole command, the
below does work.
def isSolid(mesh):
pymel.core.runtime.ParticleFill(pymel.core.general.select(mesh, r=True))
nucleusNodes = pymel.core.general.ls(type=pymel.core.nodetypes.Nucleus)
nParticles = pymel.core.general.ls(type=pymel.core.nodetypes.NParticle)
if not nParticles:
return 0
else:
pymel.core.general.delete(nucleusNodes)
pymel.core.general.delete(nParticles[0].getParent())
return 1
