Now to complete the exercise we will extrude our 3 curves to create the final Spanner 3D model.

1.Select all the curves by using a crossing window selection:

2.Select the 3 closed curves.

3.Select Iso from the View Toolbar

4.From the Solid Modeling Ribbon Bar, select Extrude.

5.Preview curves will appear to determine the direction of extrusion.
Set the extrusion to point in the positive Z direction by moving the cursor above the geometry.
Then type 1.0 in the command input bar and press the <Enter> key.
 
Command Prompt:
Extrude:: Enter extrusion distance::[L=1.000000]

6.Save the file as Spanner_Completed.vcp.
 
This completes this exercise.
