Analyzing "Open" poly curves to find the problem

This has probably been ask before; however, I didn’t find anything. I have some poly curves that tell me under “what” —that I have a valid curve, made up of (say) 79 open poly curves. It shown up a a joined object.

Question: How do I analyze what is wrong, fix it, and get “closed poly curves”

Hi Joe - use CrvEnd and CrvStart to see where the open curve’s ends are. You can manually repair in whatever way seems appropriate, or use CloseCrv.
