It would be great is Nastran could support the patterning of connectors.
Use case example: When testing a bolted pully/cog and hub assembly each bolt connector must be added in manually. If the part in question had a substantial number of bolts (i.e. a huge ring gear on the base of an excavator) it would take way too long to individually add the connectors. The alternative of using the solids would be exceptionally taxing and lengthen the analysis time by a huge factor.
