You can use the Node object snap to draw an object by snapping to the point
objects. You can then remove the points by entering
erase previous
.
The markers are placed in the user coordinate system (UCS) of the object being
measured (except for 3D polylines in the current UCS). Markers are always
placed on the object, regardless of the elevation settings.
If you use point objects for the markers, you can make the points easier to see
by changing their appearance with the PDMODE system variable.
Length of Segment
Places point objects at the specified interval along the selected object,
starting at the endpoint closest to the point you used to select the object.
Measurement of closed polylines starts at their initial vertex (the first one
drawn).
Measurement of circles starts at the angle from the center set as the current
snap rotation angle. If the snap rotation angle is 0, then the measurement
of the circle starts to the right of center, on its circumference.

The illustration shows how MEASURE marks 0.5-unit distances along a
polyline, with the PDMODE system variable set to 35.
