LSBA, NL, NA, SEPO, KEEPL, KEEPA
Subtracts areas from lines.
NLLine (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.
NAArea (or areas, if picking is used) to be subtracted. If
ALL, use all selected areas. A component name may also be substituted for NA.
SEPOBehavior if the intersection of the lines and the areas 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. |
KEEPLSpecifies whether NL lines are
to be deleted:
KEEPASpecifies whether NA areas are
to be deleted:
Generates new lines by subtracting the regions common to both NL lines
and NA areas (the intersection) from the NL lines.
The intersection can be a line(s) or keypoint(s). If the intersection is
a keypoint and SEPO is blank, the NL line
is divided at the keypoint and the resulting lines will be connected, sharing
a common keypoint where they touch. If SEPO is
set to SEPO, NL 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.
