lsbw

Booleans.lsbw(nl='', sepo='', keep='', **kwargs)

Subtracts the intersection of the working plane from lines (divides lines).

Mechanical APDL Command: LSBW

Parameters:

nlstr

Line (or lines, if picking is used) to be subtracted from. If NL = 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 input for NL.

sepostr

Behavior of the created boundary.

• (blank) - The resulting lines will share keypoint(s) where they touch.

• SEPO - The resulting lines will have separate, but coincident keypoint(s).

keepstr

Specifies whether NL lines are to be deleted:

• (blank) - Use the setting of KEEP on the boptn command.

• DELETE - Delete NL lines after lsbw operation (override boptn command settings).

• KEEP - Keep NL lines after lsbw operation (override boptn command settings).

Notes

Generates new lines by subtracting the intersection of the working plane from the NL lines. The intersection will be a keypoint(s). The working plane must not be in the same plane as the NL line(s). If SEPO is blank, the NL line is divided 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. 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. Areas that completely contain the input lines will be updated if the lines are divided by this operation.
