LDELE, NL1, NL2, NINC, KSWP
Deletes unmeshed lines.
NL1, NL2, NINCDelete lines from NL1 to NL2 (defaults
to NL1) in steps of NINC (defaults
to 1).  If NL1 = ALL, NL2 and NINC are
ignored and all selected lines [LSEL] are deleted.  If NL1 =
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 NL1 (NL2 and NINC are ignored).
KSWPSpecifies whether keypoints are also to be deleted:
0  | —  | Delete lines only.  | 
1  | —  | Delete lines, as well as keypoints attached to lines but not attached to other lines.  |
