, KEEP1
, KEEP2
Subtracts lines from lines.
NL1
Line (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 forNL1
.NL2
Line (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 forNL2
.SEPO
Behavior if the intersection of the
NL1
lines and theNL2
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.
KEEP1
Specifies whether
NL1
lines are to be deleted:KEEP2
Specifies whether
NL2
lines are to be deleted:
Notes
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.
