What is the purpose of the Chord Length dimension in SolidWorks?

The Chord Length dimension in SolidWorks specifically measures the straight-line distance from one endpoint of an arc to the other endpoint. This is particularly useful in many engineering applications, where knowing the direct linear distance across a curve can influence design decisions. The chord length provides a quick method to evaluate how far apart two points on an arc are, which can be essential for understanding clearances, fitting conditions, and other geometrical relationships in a design context.

The chord length is distinct from measuring the arc length, which represents the distance along the curve itself, or determining the angle of the curve, which refers to how the curve is oriented. By focusing on the straight-line distance, the Chord Length dimension allows designers to simplify calculations and create precise geometry that fits within the constraints of their designs.
