*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.

Product: Abaqus/Standard  

Type: Model data

Level: This option is not supported in a model defined in terms of an assembly of part instances.

Reference:

Required parameter:

ELSET

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

Optional parameter:

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.
