Conduits and Item Types

Question

Folks: 
 I would like to know how the members are assigning multiple Item Types to a singular conduit feature definition in OpenRoads Drainage and Utilities. 
 Some background: We have- for instance- a single feature definition- "RCP" (Reinforced Concrete Pipe) which is tied to the Hydraulic Prototype (RCP) which is accessing the Conduit Catalog for various sizes related to this feature definition (18", 24", 30", etc.). Because we have different Pay Items that need to be assigned to different sizes of pipe- and as I have only the feature definition "RCP" which I can assign an Item Type to- how can I get the software to understand different Pay Items based upon the size of the conduit I need? I was hoping that there would be a place in the Conduit Catalog where such an Item Type could be assigned, but it does not seem to exist there. The absurd solution of creating feature definitions for each size and type of pipe comes to mind? 
 How are you folks handling this "issue"?

I agree that it's no fun trying to work out the syntax that you need to retrieve information, especially from the drainage and utilities databases. This Wiki article - Video: Item Type Syntax for Nodes and Conduits - OpenRoads | OpenSite Wiki - OpenRoads | OpenSite - Bentley Communities provides the syntax for some data, and also describes how to find the syntax for anything in the drainage and utilities databases. Please note the suggestion that you keep your data as simple as possible when you do this. 
 We intend to have an Expression Builder in 2022 Release 1 to make this process easier. 
 You should be able to get the material and the size values, and do what you need from there. Depending on how your bill items work, you may also want to look at the amount of cover that a conduit has, as this is a factor in some countries.
