, IMOVE
Generates areas from an area pattern by symmetry reflection.
Ncomp
Symmetry key:
X | — | X symmetry (default). |
Y | — | Y symmetry. |
Z | — | Z symmetry. |
NA1
, NA2
, NINC
Reflect areas from pattern beginning with NA1
to NA2
(defaults
to NA1
) in steps of NINC
(defaults
to 1). If NA1
= ALL, NA2
and NINC
are
ignored and the pattern is all selected areas [ASEL].
If Ncomp
= P, use graphical picking to specify
areas and ignore NL2
and NINC
.
A component name may also be substituted for NA1
(NA2
and NINC
are
ignored).
KINC
Keypoint increment between sets. If zero, the lowest available keypoint numbers are assigned [NUMSTR].
NOELEM
Specifies whether nodes and elements are also to be generated:
0 | — | Generate nodes and elements associated with the original areas, if they exist. |
1 | — | Do not generate nodes and elements. |
IMOVE
Specifies whether areas will be moved or newly defined:
0 | — | Generate additional areas. |
1 | — | Move original areas to new position retaining
the same keypoint numbers ( |
Generates a reflected set of areas (and their corresponding keypoints, lines and mesh) from a given area pattern by a symmetry reflection (see analogous node symmetry command, NSYM). The MAT, TYPE, REAL, ESYS, and SECNUM attributes are based upon the areas 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. Areas in the pattern may have been generated in any coordinate system. However, solid modeling in a toroidal coordinate system is not recommended. Areas are generated as described in the AGEN command.
See the ESYM command for additional information about symmetry elements.
