When Parts of a Drawing Align on a Common Radial

Question

When parts of a drawing align on a common radial centerline, _____ coordinate dimensions are used.
A) rectangular
B) polar
C) tabulated outline
D) circular

Accepted Answer

Polar coordinate dimensions are used when parts of a drawing align on a common radial centerline. Polar coordinates are defined by a distance from a fixed point (the centerline) and an angle from a fixed reference direction (usually horizontal). This makes them ideal for specifying the locations of features that are arranged in a circular pattern.
