[SAC] Switch cases as parameters

[RRamirezVizuete]

Hello,

I am trying to model a corridor using just one assembly that has different branches depending on conditions (is there a shoulder, is there an auxiliary lane...?).

The cross slopes of lanes and shoulders are controlled via corridor transitions, as the slopes are parameters built into a custom subassembly.

The corridor has also barriers of different types. For that, I created a custom subassembly that displays a different barrier depending on the user input (the subassembly has an enumeration type defined for each type of barrier and uses the switch flow). I tried to control the different cases via corridor transition, but the barrier type is not shown in the tool as a parameter, even though is treated by Civil 3D as such.

Does anybody have other solution than creating a horizontal target, so the assembly branches off depending on the barrier type found in the drawing?

I just wished Civil 3D had a more parametric approach to these types of cases.

Thank you,
