I'm trying to generate a profile using acad 2009.  When I create a TIN surface and when I import my points the boundry line doesn't surround all of my points.  Causing gaps in the grade line when i generate my profile?  I'm lost on how to ensure that the surface boundry line surrounds all my points?  Please help before i smash my computer!  LOL!

Well seems to be so funny. Now the time I can't give you the exact information about this. I will tell you after consult it with my friend.
