A. Dear Jeff Wintle,
first calculate the area for the fastener, this you will get from drawing.(in pro-E, you are able to get the ex-cast surface area) convert the area in square meter.
EX:
Assume one fastener(with out plating or coating) is 0.1 Square meter and the weight is 100 gms, Total 10 of fasteners is 1000 gms with 1 Square meter. after the plating all 10 Number weight should be 1015.
For setting the base from initial define the Each part area then you will fix.
I think the above will help for your requirement.
