public class PgRuler

extends PgPolygonSet

A Ruler has an origin in 3-space, a direction in 3-space, and min and max exents along this so-defined line - thus we allow for the origin, direction, and extents of the ruler to be externally controlled. Based on this data, the ruler itself will configure its' appearance according to specifications given in its configuration panel.

Version:

27.09.00, 1.01 revised (spd) measure was added to make the ruler act as a measuring tape. Set the origin for the anchor point with setInitPoint then pass this the endpoint.
07.07.00, 1.00 created (spd)

setInitPoint

public void setInitPoint(PdVector P)

measure

public void measure(PdVector P)

Measure, is a way of using the ruler as a Tape measure. To use this method you simply need to pass it an enpoint from which a measurement is made from the currently defined ruler origin set via #setInitPoint(). Hashings will only be automatically visible if measurements are made in the xy,yz, or xz perspectives. For the arbitrary perspective case you must explicity give a direction in which to draw the hash, else results may be unpredictable.

labelside: - which side of the label to attach to the label origin :={ALIGNLEFT(0),ALIGNRIGHT(1)}

xoff: - how much to offset the label from the label origin in the x direction

yoff: - how much to offset the label from the label origin in the y direction
