VSBW, NV, SEPO, KEEP
Subtracts intersection of the working plane from volumes (divides
volumes).
NVVolume (or volumes, if picking is used) to be subtracted from.
If NV = ALL, use all selected volumes. If NV =
P, graphical picking is enabled (valid only in the GUI). A component name
may also be input for NV.
SEPOBehavior of the created boundary.
(blank) | — | The resulting volumes will share area(s) where they touch. |
SEPO | — | The resulting volumes will have separate, but coincident area(s). |
KEEPSpecifies whether NV volumes are
to be deleted.
Generates new volumes by subtracting
the intersection of the working plane from the NV volumes.
The intersection will be an area(s). If SEPO is
blank, the volume is divided at the area and the resulting volumes will be
connected, sharing a common area where they touch. If SEPO is
set to SEPO, the volume is divided into two unconnected volumes with separate
areas. The SEPO option may cause unintended consequences if any keypoints
exist along the cut plane. 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.
Issuing the VSBW command under certain conditions may generate a topological degeneracy error. Do not issue the command if:
A sphere or cylinder has been scaled. (A cylinder must be scaled unevenly in the XY plane.)
A sphere or cylinder has not been scaled but the work plane has been rotated.
