, KEEP2
Subtracts areas from areas.
NA1
Area (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 forNA1
.NA2
Area (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 forNA2
.SEPO
Behavior if the intersection of the
NA1
areas and theNA2
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.
KEEP1
Specifies whether
NA1
areas are to be deleted:KEEP2
Specifies whether
NA2
areas are to be deleted:
Notes
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.
