Reply To: How to create paths in a curve surface in a easy way

I did understand what you wanted, and the method I suggested is the only way in Mechanical, other than making a bunch of two-point paths as you have done with node coordinates.

If you make an edge imprint on a face before meshing, then it will have a mesh gridline along the edge. For your picture above, you could make a construction path using the edge at the geomtry corner at T1. For T10, you would need to make an edge imprint on the geometry face before meshing. This is the only way the Mechanical GUI allows you to do this.

Any other method would need to be done with APDL commands. Sorry, but I don't have the commands to do this. But you would need to supply it with a list of nodes for each path, in order of the direction of each path. Or the typical way we communicate Mechanical with APDL is to send named selections which you can retrieve wth CMSEL command. But in this case you would want to make an edge imprint on the face and place the edge into a named selection. And my previous method already required you to make an edge imprint, so you might as well use that method.

You could make a named selection of nodes. Your APDL script would need to figure out the order of the nodes to create a path.
