Creating a rib

The Add mode of the Project tool can be used to create ribs.

To create a rib:

1.      In the desired view, draw a 2D object or NURBS curve on top of a solid.

The 2D object or NURBS curve must be closed and planar.

2.Click the tool and mode.

3.Click the appropriate projection direction mode (Add Upward, Add Downward, or Add Both Directions).

4.Click on the object to add, and then click on the solid.

The rib profile is projected until it meets the next surface it encounters. The profile is trimmed at the extremities automatically.
