DIVIDE - MEASURE

DIVIDE

You can divide a selected object into a specified number of equal lengths. DIVIDE creates points or insert blocks on an object at a specific number of equal intervals. This operation does not actually break an object into individual objects; it only identifies the location of the divisions so that you can use them as geometric reference points.

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.

MEASURE

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.

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 using several methods. To change the point style in a dialog box, you can use DDPTYPE, or choose Point Style from the Format menu. The PDMODE system variable also controls the appearance of point markers. For example, you can change the value to make points appear as crosses. PDSIZE controls the size of point objects.

The points or blocks drawn by MEASURE are placed in the Previous selection set, so you can choose them all by entering p at the next Select Objects prompt. 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.
