Commands
DDPTYPE
Specifies the display style and size of point objects.
POINT
Creates a point object.
System Variables
PDMODE
Controls how point objects are displayed.
PDSIZE
Sets the display size for point objects.
Draw Construction Lines (and Rays)
Lines that extend to infinity in one or both directions, known as rays and
construction lines, respectively, can be used as references for creating other
objects.
For example, you can use construction lines to find the center of a triangle,
prepare multiple views of the same item, or create temporary intersections to
use for object snaps.
Infinite lines do not change the total area of the drawing. Therefore, their
infinite dimensions have no effect on zooming or viewpoints, and they are
ignored by commands that display the drawing extents. You can move, rotate,
and copy infinite lines just as you can move, rotate, and copy other objects.
You may want to create infinite lines on a construction line layer that can be
frozen or turned off before plotting.
Construction Lines
A construction line (also known as xlines) can be placed anywhere in
three-dimensional space. You can specify its orientation in several ways. The
default method for creating the line is the two-point method: you specify two
points to define the orientation. The first point, the root, is the conceptual
midpoint of the construction line, that is, the point snapped to by the
Midpoint object snap.
