2.  Create areas for mold and casting.

Now create an area for the mold by connecting the four keypoints.

1. Main Menu:  Preprocessor
        -Modeling-Create
             -Areas-Arbitrary
                  Through KPs
2. Pick keypoints 1 through 4 in sequential order.  You can see the lines form as you pick.

3. OK to create area (in picking menu)

4. Toolbar:  SAVE_DB

To create the area for the casting, "carve out" the area from the first area.  This is done by creating a rectangle primitive (don't worry about the exact dimensions on the right side; it can be longer than it needs to be), overlapping the areas (Boolean operation), and then deleting the extraneous area left over.

        -Modeling-Create
