You must often create landing curves when creating profile systems and seams by projection. Landing curves are sometimes based on existing grid planes created with the Grids task. There are two methods for defining the landing curve:

Define using 2D Sketcher

Defines a landing curve by projecting a 2D curve that is sketched onto the plate systems.

Landing Curve Definition by 3D

Defines a 3D geometric construction landing curve by creating a curve through a set of points, a set of curves on the plate system, or a surface intersecting the plate system. For more information, see Geometric Constructions.
