Use : To build new structures from existing models/substructures using transformation matrices to achieve the correct spatial relationship between components of the structure. Parameter NAME can thus refer to an existing model or to a previously defined substructure, enabling multi-level substructures to be defined. This routine will assemble model/substructure components under the model name which was previously passed to routine DIHED (with OPCODE = 3).

The transformation matrix identification numbers must refer to transformation matrices which were previously input along with model/substructure name NAME. The transformations to which these identification numbers refer are concatenated internally to form a single matrix. This resultant matrix is used to locate the model/substructure correctly within the new assembly. Parameter NUMTRA may thus be zero if the model/substructure is already located correctly, or possibly 1 if the user already has access to a single compound transformation matrix.
