ROLLPLAN

The cutting plan of a roll's drops: the lengths cut from the roll one after another, each the drop's length and a trim allowance at both ends.

Syntax

ROLLPLAN(floor, width, angle, origin, trim, at)

Argument	Meaning
floor	The floor: an element, or a list of them (`{@1,@4}`: a room and its doorway), closed outlines joined into one.
width	The roll's width.
angle	The way the drops run (the pile's direction), in degrees anticlockwise from the X axis.
origin	A position the first seam runs through.
trim	The trim allowance at each end of a length.
at	Where the plan starts (the start of the roll, its lower left).

Result

A list, a length each: {cut, piece, label position, number, length cut}: the length's outline on the roll and the drop's shape in it (each a list of positions), where its label goes, the drop's number, and the length cut (the drop's and twice the trim).
