LSBV, NL
, NV
, SEPO
, KEEPL
, KEEPV
Subtracts volumes from lines.
NL
Line (or lines, if picking is used) to be subtracted from.
If ALL, use all selected lines. If NL
= 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 NL
.
NV
Volume (or volumes, if picking is used) to be subtracted.
If ALL, use all selected volumes. A component name may also be substituted
for NV
.
SEPO
Behavior if the intersection of the NL
lines
and the NV
volumes 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. |
KEEPL
Specifies whether NL
lines are
to be deleted:
KEEPV
Specifies whether NV
volumes are
to be deleted:
Generates new lines by subtracting the regions common to both NL
lines
and NV
volumes (the intersection) from the NL
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.
