*SUBSTRUCTURE PROPERTY

Translate, rotate, and/or reflect substructures.

This option is used to define properties for a substructure. It is required for all substructures in a model.

TypeModel data

LevelThis option is not supported in a model defined in terms of an assembly of part instances.

Required parameters

ELSET

Set this parameter equal to the name of the element set containing the substructures for which properties are being defined.

Optional parameters

POSITION TOL

Set this parameter equal to the tolerance on the distance between usage level nodes and the corresponding substructure nodes. If this parameter is omitted, the default is a tolerance of 10−4 times the largest overall dimension within the substructure. If the parameter is given with a value of 0.0, the position of the retained nodes is not checked.
