Auxiliary Views and Pro-E By: Adolfo Lozano Nathaniel Olivarez Troy Wipf
Auxiliary ViewsWhat are they? • They are views derived from any plane except the frontal, horizontal, or profile planes • They are termed primary and secondary • These views are used to show the true shape of an inclined or oblique surface
Memorize! • A fold line that is parallel to a line gives a view that shows the “true length” of the line • A fold line that is perpendicular to a “true length”line on a surface gives a view that shows the surface as an edge • A fold line that is parallel to the edge view of a surface gives a view that shows the “true shape” Dr. Crown, Lecture Notes 7, Slide 21
Remember… • For an inclined surface: primary auxiliary view shows true shape • For an oblique surface: primary auxiliary view shows surface as an edge, while secondary auxiliary view shows true shape
Problem • How do engineers use Pro-E to create oblique surfaces?
Solution • Through the use of Datum tools such as datum planes, datum points, and datum curves
Datum Points • Datum points can go on a surface or an edge of an object • These points can help position datum planes so that they cut through an object

Scenario As we were transporting the catapult to the enemy fortress in the middle of the night, we were suddenly ambushed by hostile enemy forces. Tragically, we lost several thousand men in this battle, but were able to ward off the few hundred attackers. It was then when we realized that our catapult lacks any kind of shielding device. Thus, you now have a new assignment: create a shielding device for the catapult. This addition or modification to the catapult must serve a twofold purpose: one, to protect the catapult from flaming arrows launched by these hostile enemy forces (as you can see behind me), and two, serve as a kind of water drain for the catapult in case we get caught in stormy weather. Although we currently have one idea, we need you to think of at least two more ideas for the design of the shield, roughly following the six-step Design Process that I know you have learned. So go to Linnaeus in the next tent with your two ideas.
