lin_ang - Geometric procedure

Creates a line


Description

Creates a 2D or 3D line with arbitrary start, direction and length.

Syntax

lin_ang(id, p, dir, len:attributes);

REF	id;
VECTOR	p;
FLOAT	dir;
FLOAT	len;

Principal parameters

id	- Local identity.
p	- Starting position
dir	- Direction, counterclockwise angle from positive X-axis of active coordinate system
len	- Length

Optional parameters

None.

Attributes

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

Example

lin_ang(#1,vec(10,10),90,100:LFONT=1);

Creates a dashed line starting in X=10 and Y=10 with same direction as positive Y-axis and length = 100.

Comments

In a 3D module the resulting line is restricted to the XY-plane of the active coordinate system. If the Z-component of the input position p is not zero then p will be projected along the Z-axis onto the active XY-plane before the line is created.
