Define Centerline

Now we need to define the centerline of the projectile. Many bitmaps may be slightly askew which would affect your modeling. The centerline allows this tool to correct for alignment issues.

To define the centerline:

Go to the second tab, Centerline, on the ribbon bar
Notice the centerline status message, "Centerline Not Yet Defined"
Click the Centerline Button
A few clicks of the mouse will select four points to define the centerline. The next two slides will detail the point selection.
