;
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.
6ROYH : 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.
