NWPLAN, WN, NORIG, NXAX, NPLAN
Defines the working plane using three nodes.
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.
NORIGNode number defining the origin of the working plane coordinate
system. If NORIG = P, graphical picking is enabled
and all remaining command fields are ignored (valid only in the GUI).
NXAXNode number defining the x-axis orientation (defaults to the x-axis being parallel to the global X-axis; or if the normal to the working plane is parallel to the global X-axis, then defaults to being parallel to the global Y-axis).
NPLANNode number defining the working plane (the normal defaults
to the present display view [/VIEW] of window WN).
Defines a working plane to assist in picking operations using three nodes as an alternate to the WPLANE command. The three nodes also define the working plane coordinate system. A minimum of one node (at the working plane origin) is required. Immediate mode may also be active. See the WPSTYL command to set the style of the working plane display.
This command is valid in any processor.
