Function: pcur

Syntax

pcur ({<point> {,<cursor> {,<crosshair>}}})

Type

point

Returns

A 3-D point read interactively via the mouse.

Parameters

• <point>
  Use any required coordinates from <point> when converting from 2-D to 3-D. If omitted, the current value of gc is used. If the current view is not a plan or elevation, the computed value is the intersection of the eye line and the plan plane through <point> or gc. This point is also used to set (warp) the initial position of the mouse (unless omitted or null, in which case the mouse is warped to the mid-point of the current graphic window if it is not already in that window).

• <cursor>
  The cursor to use during the mouse operation. If omitted or null, the "Maltese cross" cursor is used, unless crosshair is specified in which case only the large crosshairs are used.

• <crosshair>
  A boolean value indicating whether the large crosshairs are to be used. The default value is 0.

Examples

Allows the user to indicate a point in a graphic window.

point p = pcur

The same, but using the large crosshair.

point p = pcur(null,null,1)

Allows the user to indicate a point in a graphic window. The answer is computed in the plane passing through the origin of an entity my_ent.

point p = pcur(my_ent.origin)
