PLTW IED 2026 TECHNICAL DRAWING AND
CAD SKILLS FINAL ASSESSMENT
COMPLETE GUIDE
◉ Why is it important to understand the mathematics used in
physical property analysis?
Answer: The Mathematics is important for you to determine the
volume, density, mass, weight and size of the object you are
developming.
◉ A work point is an independent entity whose location is defined in
Answer: Space
◉ Work points may be placed or projected onto
Answer: Work points may be placed or projected onto circles
◉ . Work points can be constrained to the ________ points of arcs,
circles, and ellipses.
Answer: center
◉ work axis
, Answer: is a line that extends forever in __Two___ directions. Work
axes are useful for locating the __Center__of a _Hole__ or __Cylinder__,
are used in the creation of Revolved_ features, and may be
_Constrained_ to in assembly models
◉ Work Plane
Answer: are continuous ______Two Dimensional planes that can be
used to establish Sketch_ planes. __Assembly__ constraints can also
be applied to work planes.
◉ Why do engineers perform reverse engineering on products?
Answer: Engineers preform reverse engineering on an item to learn
how it operates and how internal parts were constructed.
Documentation
Discovery
Investigation
Product Improvement
◉ Asymmetry
Answer: Symmetry in which both halves of a composition are not
identical. Also referred to as informal balance.
