#
#  Hard Edge (he) crease is a small script for Creasing Hard Edges on a Polymesh.
#  
#  All Hard Edges on all selected objects will be assigned a full (10) crease.
#  It's pretty easy to modify the script for a less intense crease.
# 
#  Designed to be used with RenderMan for Maya with a polymesh has been tagged
#  with a subdiv scheme.  These Polymeshes are converted to subdivs at render time.
#  Polymeshes are tagged by adding a Subdiv Scheme Attribute with Attibute Editor.  
#  From the Attribute Editor, Select Add Attribute->RenderMan->Subdiv Scheme. 
#  
#  Any poly creased edge will be rendered as a Subdiv Creased Edge.
#  It seems that border edges are automatically rendered as creased edges.
