Curve Data
Many geometric properties can be used to define a curve. The most common
properties are shown in the following drawing and then described:
▶
Length
: The length of the curve, measured along its arc.
▶
Radius
: The distance from the center point of the curve to a point on the curve.
▶
Chord
: The straight line from the beginning point of the curve to the ending
point of the curve. The bearing and distance of this line can be labeled.
▶
Delta
: The change in direction between a line tangent to the curve at
its beginning point and a line tangent to the curve at its ending point.
▶
Tangent
: The distance between the point of curvature (PC) and the point
of intersection (PI) or between the point of tangency (PT) and the PI.
Depending on the requirements, you may need to include different combinations
of these curve dimensions. Typically, you must create multiple curve-dimension
labels in order to provide enough information to reconstruct a curve.
