This error appears to be common to all chassis templates in acar_shared and acar_concept databases when run on the SPMM testrig with the ges_chassis part replaced with a Flex-body except for _flex_chassis.tpl.
Has anyone generated a procedure or script to apply the entities in _flex_chassis.tpl to a standard chassis template like _rigid_chassis_bof.tpl ?
I've been switching the rigid-body to a flex-body by "modify general part" dialog box. There is a bottom for "Rigid to Flex". That brings up the "Swap a rigid for a Flexbody" dialog box. The "ges_chassis" body gets renamed to "ges_chassis_flex". A warning does come up that comminicator information is not saved in the subsystem. Afterwards the import "modify general part" dialog box looks the same except the "flexbody body modify" icon is now available. I've not had a problem opening and closing the "flexbody body modify" dialog box.
