I've noticed that when surface area is calculated in DataGroup Explorer using AECOsim Building Designer Ss5, it includes both exterior and interior surfaces for sections such square HSS members. Only the exterior surface area is required when steel framing needs fireproofing, whether sprayed with a Cementitious Fireproofing material (say 1”) or even with an Intumescent paint (say 2 mm). Is there any way to report on only the exterior surfaces for this purpose?
One of the enhancements included in the AECOsim Building Designer SELECTseries6 release is a Fireproofing tool for Structural members. It includeds both Contour and Block type Fireproofing, and not only displays as graphics but is also used when reporting through DataGroup Explorer (as well as Clash Detection).
