Angled surfaces can be dimensioned using what methods?

• A. Coordinate or angular
• B. Radius or diameter
• C. Linear only
• D. Area or volume

Answer: (A)

Defining an angled surface requires fixing its direction and where it sits on the part. You can do this by giving an angular dimension, which states the angle between the surface and a reference line, or by providing coordinates that locate the defining line or edge of the surface on the drawing. The angular method sets the tilt, while the coordinate method pins down the position. Radius or diameter apply to curved features, not a planar tilt. A single linear dimension only gives length and doesn’t convey the angle, so it isn’t sufficient on its own. Area or volume describe how much space a feature occupies, not how to dimension an angled surface.
