Function: prub

Syntax

prub (<point>, {<window> {,<cursor>}})

Type

point

Returns

A 3-D point read interactively via the mouse using a rubber band drawn from an anchor pointer.

Parameters

• <point>
  Use this point as the anchor point for the rubber band. The point is also used to satisfy any required coordinates when converting from 2-D to 3-D. If the current view is not a plan or elevation, the answer is computed from the intersection of the eye line and the plan plane through the point selected via the mouse.

• <window>
  The graphic window to be used as input. If omitted, the current graphic window is used.

• <cursor>
  The cursor to use during the mouse operation. If omitted, the large crosshairs is used.

Examples

Allows the user to indicate a point in a graphic window using the graphic control position (gc) as anchor for the rubber band.

point p = prub(gc)

Allows the user to indicate a point in a new window using a point (600,500,0) as anchor for the rubber band.

window mywin = wgraphic; box; plan
point myp = (600,500,0)
point p = prub(myp,mywin)
