Correct use of NET_SPACING_TYPE net property to drive high voltage spacing constraints

Lee W

In hierarchical designs, I have found that engineers are able to assign a single net to different NET_SPACING_TYPE classes at different levels of the schematic hierarchy.  Ultimately,  the flat net can only be assigned to one class.  

Should the Schematic Nets tab or Flat Nets tab be used when editing the NET_SPACING_TYPE properties in a hierarchical schematic?

Thanks!
