KCLEAR, NP1, NP2, NINC
Deletes nodes and point elements associated with selected keypoints.
NP1, NP2, NINCDelete mesh for keypoints NP1 to NP2 (defaults
to NP1) in steps of NINC (defaults
to 1).  If NP1 = ALL, NP2 and NINC are
ignored and the mesh for all selected keypoints [KSEL]
is deleted.  If NP1 = P, graphical picking is enabled
and all remaining command fields are ignored (valid only in the GUI).  A component
name may also be substituted for NP1.
Deletes all nodes and point elements associated with selected keypoints (regardless of whether the nodes or elements are selected). Nodes associated with non-point elements will not be deleted. Attributes assigned as a result of KATT are maintained. In the program's response to the command, if a keypoint is tallied as "cleared," it means either its node or element reference was deleted.
