AE 421 - Week 2
Orthographic projection - ANS-a system of drawing views of an objection using
perpendicular projectors from the object to a plane of projection

Multi view - ANS-series of orthographic projections

Remember 3 things when defining a view - ANS-stationary point, plane of project,
projection vector

six basic views - ANS-top, front, bottom, left side, right side, rear (glassbox)

first angle projection - ANS-right side, front view next to each other; top view below front
view

third angle projection - ANS-top view, front view under top view, right side view next to
front view

distances can be transferred or projected from one view to another - ANS-true

only the views necessary to fully describe the object should be drawn - ANS-true

Single curved - ANS-curvature about a single axis

double curved - ANS-curvature about two axes or complex curvature

Contours - ANS-main outlines that separate it from surrounding space

oblique pictorials - ANS-one face is parallel to the plane, circular shapes parallel to view
are shown true to shape
