LSBL, NL1, NL2, SEPO, KEEP1, KEEP2
Subtracts lines from lines.
NL1Line (or lines, if picking is used) to be subtracted from.
If ALL, use all selected lines. Lines specified in this argument are not
available for use in the NL2 argument. If P, graphical
picking is enabled (valid only in the GUI) and all remaining fields are ignored.
A component name may also be substituted for NL1.
NL2Line (or lines, if picking is used) to subtract. If ALL,
use all selected lines (except those included in the NL1 argument).
A component name may also be substituted for NL2.
SEPOBehavior if the intersection of the NL1 lines
and the NL2 lines is a keypoint or keypoints:
(blank) | — | The resulting lines will share keypoint(s) where they touch. |
SEPO | — | The resulting lines will have separate, but coincident keypoint(s) where they touch. |
KEEP1Specifies whether NL1 lines are
to be deleted:
KEEP2Specifies whether NL2 lines are
to be deleted:
Generates new lines by subtracting the regions common to both NL1 and NL2 lines
(the intersection) from the NL1 lines. The intersection
can be a line(s) or point(s). If the intersection is a point and SEPO is
blank, the NL1 line is divided at the point and
the resulting lines will be connected, sharing a common keypoint where they
touch. If SEPO is set to SEPO, NL1 is
divided into two unconnected lines with separate keypoints where they touch.
See the Modeling and Meshing Guide for an illustration. See the BOPTN command
for an explanation of the options available to Boolean operations. Element
attributes and solid model boundary conditions assigned to the original entities
will not be transferred to the new entities generated. LSBL,ALL,ALL
will have no effect since all the lines (in NL1)
will be unavailable as NL2 lines.
