Ask with the Structure drop option

Question

Good morning Bentley teacher

I am designing a sanitary sewer and I have doubts regarding the drop chamber.

In the options of Default Design Contrainst-Node = There is the option for the program to create these fall chambers when there is a difference between the starting pan elevation and the final pan elevation.

But I am not applying this design parameter that I am making, this is because I have too high slopes and I require these chambers.

Hello Jefry, 
 Do you mean you want to see the drop structures in the model and you have applied to do so in default constraints, but you do not see drop structures in profiles? Please confirm. 
 Please note that even if you specify to allow drop structures , it does not necessarily mean that it will always create one, rather that it will have the freedom to do so if it needs to in order to meet constraints. For example, if the network is set up in such a way that a drop structure could be used to prevent the Maximum Slope constraint from failing, it may do so. 
 What is a drop manhole and how do I model one? 
 Reporting drop depth of a manhole or catchbasin
