Click Nonlinear Extruded Plate System on the vertical toolbar.

Specify the grid plane for the extruded curve using one of the following methods:

Define plane as coincident
Define plane using offset from plane
Define plane using angle from plane
Define plane using point and vector
Define plane using three points
Define plane by vectors normal 
Click Add Intersecting Item .

Select objects in the model that intersect the sketching plane that you want to use as reference geometry. These extra objects appear in the Sketch 2D environment.

Click Add Projection Item .

Select objects in the model that do not intersect the sketching plane that you want to use as reference geometry. These extra objects are projected onto the sketching plane and appear in the Sketch 2D environment.

Click Sketch 2D .

In the Sketch 2D environment, sketch the extruded curve.
Be sure to read Sketch 2D Best Practices.

Click Finish in the Sketch 2D environment.

Click Mother Curve Definition .

Specify the sketching plane for the mother curve using one of the following methods:

Define plane as coincident
Define plane using offset from plane
Define plane using angle from plane
Define plane using point and vector
Define plane using three points
Define plane by vectors normal

Click Sketch 2D .

In the Sketch 2D environment, sketch the mother curve for the extruded plate system.

Click Finish in the Sketch 2D environment.

Click Define Boundaries .

Define the plate system boundaries using one or more of the following methods:

Click Accept .

If the boundary definition results in more than one solution, you must select bounded areas that together compose the total bounded area. Pick the needed solutions using the following procedure:

Set the remaining plate system properties.
