Opening the Model
First, you open the model and examine some components.
- Open install_dir\samples\whatsnew\surfaces\multiface-surf-extrude_example.SLDPRT.

- Notice the surface extrude features in the FeatureManager design tree.
The two extrusions into and out of the central portion of the model were created by selecting three faces, deleting the original faces, and capping one end of the extrusion.
