Hello everyone,

I'm modeling a a simple sewer system. For that I need to define the specific geometry for each sewer of the system. However, when I introduce it, the shape curve viewer only show me the bottom half of my sewer.

Is it simply a problem with the viewer or does SWMM ignore the upper half for certain a reason? I'm afraid this will have an influence on the storm water flow calculation. 

In the linked picture, you can see on the right the sewer I would like to represent in SWMM and on the left what SWMM show me.

I introduced the values manually in the Shape Curve Editor

Thanks for your help.

Best,

Nicolas
