VSYMM, Ncomp, NV1, NV2, NINC, KINC, NOELEM, IMOVE
Generates volumes from a volume pattern by symmetry reflection.
NcompSymmetry key:
X | — | X symmetry (default). |
Y | — | Y symmetry. |
Z | — | Z symmetry. |
NV1, NV2, NINCReflect volumes from pattern beginning with NV1 to NV2 (defaults
to NV1) in steps of NINC (defaults
to 1). If NV1 = ALL, NV2 and NINC are
ignored and the pattern is all selected volumes [VSEL].
If NV1 = P, graphical picking is enabled and all
remaining command fields are ignored (valid only in the GUI). A component
name may also be substituted for NV1 (NV2 and NINC are
ignored).
KINCKeypoint increment between sets. If zero, the lowest available keypoint numbers are assigned [NUMSTR].
NOELEMSpecifies whether nodes and elements are also to be generated:
0 | — | Generate nodes and elements associated with the original volumes, if they exist. |
1 | — | Do not generate nodes and elements. |
IMOVESpecifies whether volumes will be moved or newly defined:
0 | — | Generate additional volumes. |
1 | — | Move original volumes to new position
retaining the same keypoint numbers ( |
Generates a reflected set of volumes (and their corresponding keypoints, lines, areas and mesh) from a given volume pattern by a symmetry reflection (see analogous node symmetry command, NSYM). The MAT, TYPE, REAL, and ESYS attributes are based upon the volumes in the pattern and not upon the current settings. Reflection is done in the active coordinate system by changing a particular coordinate sign. The active coordinate system must be a Cartesian system. Volumes in the pattern may have been generated in any coordinate system. However, solid modeling in a toroidal coordinate system is not recommended. Volumes are generated as described in the VGEN command.
See the ESYM command for additional information about symmetry elements.
