*Methodology*
Command:	-11
Alpha Alias:	Os PlineRoW
Description:	Computes pairs of points along easement right-of-way without curves
Data Format:	-11 RW-Width Set StartingTangent PI-Ahead {[PI-Ahead]..} ;
Problem:	Given points of intersection 1 through 5, set right-of-way points 21 through 26.
Solution:	-11 30 21 1 2 3 4 5 ;

Data Description

Command	-11	Computes Points of Intersection (PI) in pairs along an easement right-of-way without curves.
RW-Width	30	Width of the right-of-way. If it is necessary to change the right-of-way width, you must execute another -11 command.
Set	21	Point number to be assigned to the initial point on the right-of-way to be computed. The additional points computed are numbered automatically from this Set point. The point numbers are assigned in pairs at each PI. If the tangent ahead deflects to the right, the smaller point number of the pair is set to the right of the centerline. If the tangent ahead deflects to the left, the smaller point number of the pair is set to the left of the centerline.
StartingTangent	1, 2	Defines the first tangent with two previously computed points. The first value must be the point number of a point-on-tangent preceding the alignment, and the second is the point number of the PI on the tangent.
PI-Ahead	3	Point number of a previously computed Point of Intersection on the centerline.
{[PI-Ahead]..}	4 5	Repeating feature of this command. Enter point numbers of previously computed Points of Intersection on the centerline. Enter a point for each pair of right-of-way Points of Intersection you want computed.
End Command	;	All commands end with a semi-colon.
