Creates a line


Description

Creates a line tangent to two arcs. Possible tangency alternatives are enumerated along the first arc and an alt parameter must be supplied to select the right solution.

Syntax

lin_tan2(id, ref1, ref2, alt:attributes);

REF	id;
REF	ref1;
REF	ref2;
INT	alt;

Principal parameters

id	- Local identity
ref1	- Identity of first arc
ref2	- Identity of second arc
alt	- Requested tangency alternative

Optional parameters

None.

Attributes

PEN	- Pen or colour number
LEVEL	- Level number
BLANK	- Visible(0) or invisible(1)
LFONT	- Solid(0), dashed(1) or centerline(2)
LDASHL	- Dashlength
WIDTH	- Linewidth
