*Methodology*
Command:	1.4
Alpha Alias:	Set Lots
Description:	Defines lot corners by specifying lot width at building restriction line
Data Format:	1.4 Set BRL-Length SetBacks FrontBlockLines ;
Problem:	Points 1 through 12 and point 20 are known. Compute points 21 through 34 so that each lot will be exactly 100 feet at the building restriction line.
Solution:	1.4 21 100 -30 -30 2 3 4.1 5 6.1 7 8 ;

Data Description

Command	1.4	Defines lot corners so that each lot has a specified lot width or arc length at the building restriction line (BRL). Rear lot corners must be defined using the -17 command prior to execution of this command.
Set	21	Point number to be assigned to the first lot corner computed. The automatic numbering of front lot corners increases by two. Rear lot corners are numbered one greater than their companion front lot corner point number.
BRL-Length	100	Desired lot width or arc length at the building restriction line (BRL).
Setbacks	-30,-30	Set back distances to the BRL from the front block lines. The front block lines are considered to be directed lines. You must enter the two set-back distance values: the first for front block lines that curve to the left; the second for front lines that curve to the right. Enter the set-back value as positive values when the BRL lies to the right of the front lines. Enter negative values when the BRL lies to the left of the front lines.
Front-Block-Lines	2, 3, 4.1, 5, 6.1, 7, 8	Defined by previously computed and stored point numbers. If any point is a Point of Curvature, you must enter the radius point number with .1 appended and then the Point of Tangency. A series of sequential point numbers may be entered using only the first and last point numbers. To do this, enter the first point number then the last point number with a preceding hyphen, e.g., 1, -5.
End Command	;	All commands end with ; (semi-colon).
