Associate geometry /hard geometry

ron.kunz
When I associate a curve with a surface, I would expect that for the meshing, the mesh would consider the complete line for the meshconnection. But it seems only the outer points are considered for the mesh, see attached picture.
I want to have a connection between 2 surfaces and this should be the way to do this?

    Sorry I wrote this before seeing Darrels.
    Yes, I would consider the mesh should follow the hard curve so if it does not then there must be some reason.
    a) are you using the Paver mesher , the iso mesher can not handle internal hard geometry? I think you are but just checking.
    b) does the "hard" curve truly lie on the surface. If the hard curve deviates by more than tolerance away from the associated surface then the surface mesh will pass underneath at that location. A "hard" curve can follow, lift off, follow etc and where it is within tolerance the surface mesh should follow and when it is outside tolerance it is ignored. does the surface need extending to meet the other one? Increase the global tolerance?
    cheers
