POLYLINE

A chain of straight lines and arcs through a list of points.

Syntax

POLYLINE [points]
POLYLINE @id,[points],closed,layer,[bulges]

Argument	Meaning
[points]	The points it passes through, in order: `[P1,P4,P5]` or `[P1..P5]`.
closed	`TRUE` to join the last point back to the first (optional: `FALSE`).
[bulges]	How much each segment bulges into an arc, one number per segment: 0 straight, 1 a half circle, positive anticlockwise, negative clockwise (optional: all straight; `NIL` for none). Each is tan(¼ of the arc's angle), as in DXF files.

The id, layer and any settings after it are the element settings.

POLYLINE @1,[P0..P3],TRUE
POLYLINE @2,[P0,P1,P2],FALSE,1,[0,0.4142]

POLYLINE example

The first is the box's outline; the second, on layer 1, runs along the bottom and then turns up to P2 with a quarter circle.

A polyline is cut and selected as one element. EXPLODE breaks it into its lines and arcs.
