ASBA, NA1, NA2, SEPO, KEEP1, KEEP2
Subtracts areas from areas.
NA1Area (or areas, if picking is used) to be subtracted from.
If ALL, use all selected areas. Areas specified in this argument are not
available for use in the NA2 argument. If P, graphical
picking is enabled (valid only in the GUI) and remaining fields are ignored.
A component name may also be substituted for NA1.
NA2Area (or areas, if picking is used) to subtract. If ALL,
use all selected areas (except those included in the NA1 argument).
A component name may also be substituted for NA2.
SEPOBehavior if the intersection of the NA1 areas
and the NA2 areas is a line or lines:
(blank) | — | The resulting areas will share line(s) where they touch. |
SEPO | — | The resulting areas will have separate, but coincident line(s) where they touch. |
KEEP1Specifies whether NA1 areas are
to be deleted:
KEEP2Specifies whether NA2 areas are
to be deleted:
Generates new areas by subtracting the regions common to both NA1 and NA2 areas
(the intersection) from the NA1 areas. The intersection
can be an area(s) or line(s). If the intersection is a line and SEPO is
blank, the NA1 area is divided at the line and
the resulting areas will be connected, sharing a common line where they touch.
If SEPO is set to SEPO, NA1 is
divided into two unconnected areas with separate lines where they touch.
See Solid Modeling in
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. ASBA,ALL,ALL
will have no effect since all the areas (in NA1)
will be unavailable as NA2 areas.
