Descriptive Geometry

Manipulating (rotating) picture planes (surfaces) in order to identify

• True size
• True shape
• True length
• True angle
• Intersection points
• Distances

True Length Lines

• If a line is parallel toa fold line in 1 view, it is true length in the next view

Point View

• You must first find a true length line
• Create a fold line perpindicular to the true length (TL) line

True Size Surface

• You must find TL of one line
• Create fold line perpendicular to the TL line to get the edge view (EV) of the surface
• Create fold line parallel to the edge view

Addaline

• Addaline allows you to skip a view when finding TL
