ASBA
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
NA2argument. If P, graphical picking is enabled (valid only in the GUI) and remaining fields are ignored. A component name may also be substituted forNA1.NA2Area (or areas, if picking is used) to subtract. If ALL, use all selected areas (except those included in the
NA1argument). A component name may also be substituted forNA2.SEPOBehavior if the intersection of the
NA1areas and theNA2areas 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
NA1areas are to be deleted:KEEP2Specifies whether
NA2areas 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.
