Civil3d Structure question

[Nole954]

i'm trying to model 2 twin 48" pipes into a structure with a 4'3 box culvert connect upstream. The only part catalog we have is FDOT and haven't had time to learn parts builder. Is there any other parts catalogs or an efficient way to model this? None of the FDOT structures have these characteristics. Ive attemped to create a struce to fit te model but the paramaters in parts builder is very complex. Any ideas or suggestions would e greatly appreciated. Basicall trying to connect a 4'3 box culvert into a modified J bottom structure with twin 48" existing CMP pipes at a 90 deg angle with channelization.

I don't know the answer, but you might get more attention to this if you put it in the AutoCAD forum instead.
