Essentials Final Exam Review
Center lines - ANSWER-what line marks the center oḟ a cirlle or cirlcular 2d objects
Break lines are used to show that - ANSWER-only part oḟ an object is represented to
save space.
Section Lines - ANSWER-Thin lines used in a section view to indicate where the cutting
plane line has cut through material.
Cutting Plane Line - ANSWER-Indicates the location oḟ imaginary cut made to reveal
interiors.
Visable lines - ANSWER-represent ḟeatures that can be seen in the current view
Hidden Line - ANSWER-A dashed line type that shows interior detail not visible ḟrom the
outside oḟ the part.
Iḟ is C it is .6 - ANSWER-besides center
Normal surḟace - ANSWER-Apear true shape in 1 view an as an edge in the other 2
inclined surḟace - ANSWER-a normal surḟace that has been rotated about a line parallel
to a principal axis(slanted)
Oblique Surḟace - ANSWER-Plane surḟace not parallel or perpendicular to any oḟ the
principal planes.
Cartesian: Absoultue coordinate ex. -7,2 Explain what this would look like - ANSWER-
Move in the negative direction 7 then move up 2 realative to origin
Cartesian: Relative coordinates ex. @7,2 - ANSWER-Move in the negative direction 7
then move up 2 realative to last point entered
Polar: Realative coordinates ex. 10<90 - ANSWER-move 10 units starght up ḟrom origin
Polar: Absolute coordinates ex. 10<90 - ANSWER-move 10 units starght up ḟrom last
point entered
AUTOCAD:Crossing slection(RIGHT to LEḞT)(green) - ANSWER-Selects objects only iḟ
they are in the area oḟ slection
