Drainage Cross Section

Hi there,

I am currently having an issue with the Subsurface Utilities within OpenRoads Desginer. 

1. I want to create a new node which would be a rectangular or a triangular cross section, since there´s only trapezoidal cross sections for this, but I had no success (I have tried to solve this issue by going to the feature definition and creating new ones, creating new prototypes and new catalog itens). Is there a way to solve this?

2. After that I also want to create new sections for some conduit which would match with those cross section that I mentioned above, I thought that if I just changed the prototype it would work out but that haven´t been the case.

Thank you,

Tomás Cinquetti
