You can
 Specify the length of the segments (MEASURE)
 Specify the number of equal segments (DIVIDE)
You can measure or divide lines, arcs, splines, circles, ellipses, and polylines.
With both methods, you can identify the intervals by inserting either a point
or a block.
By specifying points, you can use the Node object snap to align other objects
at intervals on the measured or divided object. By specifying blocks, you can
create precise geometric constructions or insert custom markers. The blocks
can rotate at each insertion point.
You cannot insert a block unless it has already been defined within the
drawing. Variable attributes within the block are not included when you insert
the block references.
The points or blocks you draw using MEASURE or DIVIDE are placed in a
selection set. Therefore, if you want to edit them immediately, you can use
the Previous option of SELECT.

Specify Measured Intervals on Objects
You can mark off equal lengths from one end of a selected object.
You can use MEASURE to mark an object at specified intervals. You can mark
the intervals with either points or blocks. The last segment of a measured
object may be shorter than the interval you specify.
The starting point for measurements or divisions varies with the object type.
For lines or open polylines, the starting point is the endpoint closest to the
selection point. For closed polylines, it is the polyline start point. For circles,
it is at the angle from the center point that is equivalent to the current snap
angle. For example, if the snap angle is 0, the circle starts at the three o'clock
position and continues counterclockwise.
If the point marker is displayed as a single dot (the default setting), you may
not be able to see the measured intervals. You can change the style of the
point markers with the Point Style dialog box (DDPTYPE). The PDMODE
system variable also controls the appearance of point markers. For example,
