entityClosed variable

[bLouChip]

Les,
In the OnPenDown() function of a post script, I'm attempting to use entityClosed SC variable to detect when I'm building gcode for an open shape as defined by the .svg import. That works fine as long as I don't use leadin or leadout on the toolpath. Using either causes every shape to appear as an open shape. I get it that a leadin or leadout technically guarantees the path will be open, so how do I detect if the "entity shape" is open or closed ?
thanks.
Lou
