1. This keyword maps to /PROP/TYPE8 (SPR_GENE) using a default mass 2.0e-03kg and inertia 2e-02 kg*mm depending on the units.
2. The option “_TITLE” can be added to the end of this keyword. When “_TITLE” is included, an extra 80 character long line is added after the keyword input line which allows an entity title to be defined.
