LSYMM
LSYMM, Ncomp, NL1, NL2, NINC, KINC, NOELEM, IMOVE
Generates lines from a line pattern by symmetry reflection.
NcompSymmetry key:
X
—
X symmetry (default).
Y
—
Y symmetry.
Z
—
Z symmetry.
NL1,NL2,NINCReflect lines from pattern beginning with
NL1toNL2(defaults toNL1) in steps ofNINC(defaults to 1). IfNL1= ALL,NL2andNINCare ignored and pattern is all selected lines (LSEL). IfNL1= P, graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI). A component name may also be substituted forNL1(NL2andNINCare 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 lines, if they exist.
1
—
Do not generate nodes and elements.
IMOVESpecifies whether areas will be moved or newly defined:
0
—
Generate additional lines.
1
—
Move original lines to new position retaining the same keypoint numbers (
KINCandNOELEMare ignored). Valid only if the old lines are no longer needed at their original positions. Corresponding meshed items are also moved if not needed at their original position.
Notes
Generates a reflected set of lines (and their corresponding keypoints and mesh) from a given line pattern by a symmetry reflection (see analogous node symmetry command, NSYM). The MAT, TYPE, REAL, and ESYS attributes are based upon the lines 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 Cartesian. Lines in the pattern may have been generated in any coordinate system. However, solid modeling in a toroidal coordinate system is not recommended. Lines are generated as described in the LGEN command.
See the ESYM command for additional information about symmetry elements.
