WPLANE, WN, XORIG, YORIG, ZORIG, XXAX, YXAX, ZXAX, XPLAN, YPLAN, ZPLAN
Defines a working plane to assist in picking operations.
WNWindow number whose viewing direction will be modified to
be normal to the working plane (defaults to 1). If WN is
a negative value, the viewing direction will not be modified. If fewer than
three points are used, the viewing direction of window WN will
be used instead to define the normal to the working plane.
XORIG, YORIG, ZORIGGlobal Cartesian coordinates of the origin of the working plane coordinate system.
XXAX, YXAX, ZXAXGlobal Cartesian coordinates of a point defining the x-axis orientation. The x-axis aligns with the projection of the line from this orientation point to the origin.
XPLAN, YPLAN, ZPLANGlobal Cartesian coordinates of the third point defining the working plane. This point will also define the location of the positive XY-sector of the working plane coordinate system.
Defines a working plane to assist in picking operations using the coordinates of three noncolinear points. The three points also define the working plane coordinate system. A minimum of one point (the working plane origin) is required. Immediate mode may also be active. See WPSTYL command to set the style of working plane display.
This command is valid in any processor.
