now work on the real form of the objects based on actual result of the
orthographic projection. This process is called _____ .
A. pictorial drawing
B. depth dimensions
C. height dimensions
D. center dimensions
ANS: C

A. 40 degrees
B. 45 degrees
C. 30 degrees
D. 60 degrees
ANS: A

true or same measurement in ____ oblique.
A. width
B. cavalier
C. specific
D. object
ANS: C
