The resulting points or blocks are always located on the selected object and their
orientation is determined by the XY plane of the UCS.

Use PTYPE to set the style and size of all point objects in a drawing.

The points or blocks are placed in the Previous selection.

You can use the Node object snap to draw an object by snapping to the point objects.

The following prompts are displayed.

Object to measure

Select the reference object along which you want to add the point objects or blocks.

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.

Block

Places blocks at a specified interval along the selected object.

Align block with object

• Yes. The block is rotated about its insertion point so that its horizontal lines are aligned
  with, and drawn tangent to, the object being measured.
• No. The block is always inserted with a 0 rotation angle.

After you specify the segment length, the block is inserted at the specified interval.
If the block has variable attributes, these attributes are not included.
