DISCONNECT START END RECALCULATE
Description:
When a Section is disconnected, the connection cross-references (JOIS/JOIE - CREF) are unset and the connection type cross-references (CTYS/CTYE ) are set to Nulref.
The position and length of the Section are not changed, but the Joint (if moved during the connection operation) is returned to its default position.
The RECALCULATE option causes the positions of elements which are members of a Section to be recalculated so that they remain in the same positions if the Section is moved. For example, the ZDIST defining the position of a Secondary Node would be recalculated if the POSS (from which ZDIST is measured) were moved as a result of a DISCONNECT command, so that the SNOD remained unmoved.
