Seemingly unusal framing object attributes

[Alaskan_Son]

Does anyone know what these particular attributes were added to framing objects for, how they were intended to be used, or where they pull their information from?  @Dermot or anyone else at Chief maybe?

 

concrete_volume......................... 0 cu ft

form_area............................... 0 sq ft

rebar_count................................. 4

rebar_extension......................... 20 in

rebar_size.................................. 5

stirrup_count............................... 8

stirrup_overlap.......................... 5 in

stirrup_size................................ 3

 

They all seem like they could provide us with some handy information but most of them also seem like they would need information from other objects.  Any help in understanding what these are would be appreciated.  Thanks.

The last six are for Solid Concrete Posts....   Would need to play a bit to see if the first two also apply to the same.

 

Also Roof and Floor Beams.

Yep.  You're right.  Got it.  Thanks.  And yes, the first 2 are for the same.
