Pull

The Pull command moves curves or point objects toward the normal direction of the selected surface or mesh to find the intersection.

When exiting the command, the newly created curves will be always be selected without regard for pre-selection.
Use the Pull command to create complex trim curves, such as a curve that goes most of the way around a cylinder.
Use the Project command if you know what the trim curve looks like from a single viewport.
Use Pull command if you know where on the surface (in 3‑D) the trim path should be. Use curve commands to draw the curve, drag the control points or edit points to move the curve near the surface. Then, use the Pull command to pull the curve onto the surface. You can also use the InterpCrvOnSrf command to create a curve on a surface.
When drawing the curves, use the fewest control points possible. This guarantees the smoothest possible trim curve.

DeleteInput

Deletes the input objects.

Keeps the input objects.

Loose

Pulls edit points back to the surface. If any edit point misses the surface, the curve will not be created.

OutputLayer

Places the results on the same layer as the input curve.

Places the results on the same layer as the target surface.
