The commands in the reference curves category allow you to create and modify 3D curves defined on any planar, knuckled, or curved surface. You can classify curves as reference, grids, marking, tangents, knuckles, paint, construction, and area limit.
-
When you create or edit a reference curve, the dialog title displays the plate system name using the format Plate System: <name of the reference plane>.
-
You can change the default colors of reference curves, seams, profile systems, and knuckle curves to enhance visibility. See Modify Reference Curve Display Colors.
Reference Curve by Intersection Command
Creates a reference curve on the selected plate system by defining the landing curve as the intersection of the selected plate system and a grid plane.
Reference Curve by Offset Command
Creates a reference curve on the selected plate system by defining the landing curve as being offset from an existing curve (such as another seam, plate boundary, profile system, or grid plane).
Reference Curve by 2D Sketch Command
Creates a reference curve on the selected plate system by projecting a 2D landing curve that you have sketched onto the plate system.
Reference Curve from External File Command
Creates and modifies knuckled reference curves.
