; Store PT : When checked, will store the computed PT point with
the specified point name.
; Store RP : When checked, the computed radius point will be stored
with the name specified here.
Solve : will compute and store the PT, and if desired, the radius
point.
Results
Radius: is the distance from the radius point to the curve.
Length: is the arc length.
Chord: is the chord length.
Delta: is the deflection angle.
Tangent: is the distance from the PC or PT to the PI.
Mid Ord.: is the distance between the curve and the chord at the
center of the curve’s length.
External: is the minimum distance between the PI and the curve.
Deg. Arc: is the deflection angle that results in a 100-ft. arc length.
Deg. Chord: is the deflection angle that results in a 100-ft. chord
length.
Segment: is the area between the arc length and the chord.
Sector: is the area between the arc length and the two edge radii.
Fillet: is the area between the arc length and the tangents.
