Thanks guys.

Got Coons Surface working--problem for that one was what appeared to be touching wasn't (even in left, top and front views).  Attaching a link between the curves ensured the connects
and it worked.  Now to figure out a useful purpose for it that can't be done better in other modes.

Gordon Surface is still a problem-so far simply doesn't work--created three simple 2d square planes.  Added four profiles, two top and two bottom connected to respective points on all three squares.  --went into the Gordon Surface control, but couldn't properly verify the selection of the  three squares or profiles-did change from red to blue, but no other activity.  Jan
