grdraw

Draws a vector between two points, in the current viewport

(grdraw from to color [highlight]) 

Arguments

from

2D or 3D points (lists of two or three reals) specifying one endpoint of the vector in terms of the current UCS. AutoCAD clips the vector to fit the screen.

to

2D or 3D points (lists of two or three reals) specifying the other endpoint of the vector in terms of the current UCS. AutoCAD clips the vector to fit the screen.

color

An integer identifying the color used to draw the vector. A -1 signifies XOR ink, which complements anything it draws over and which erases itself when overdrawn.

highlight

An integer, other than zero, indicating that the vector is to be drawn using the default highlighting method of the display device (usually dashed).

If highlight is omitted or is zero, grdraw uses the normal display mode.

Return Values

nil
