Hi bateau,

I had this problem fixed before by deleting the .dss file from the project folder and rerun the plan.

Hope it can help.

Hi mab aba,

I never had this issue so far with my bridge modeled has SA/2D connection in version 6.3. Ground is always the same than Current Terrain. It seems like it is not a problem of cells alignment with the bridge. I did the test to not enforce cells by not using the “Edit Internal Connection (Break Line) Cell Spacing…” and “Enforce Internal Connection as Breakline in 2D Flow Area” option when right clicking the SA/2D Connection in geometry Data View but it doesn’t create your situation. Have you make sure that the geometry is associated with the right terrain in RASMapper? I can’t see nothing else for now…

Hi Simon,

I had the same situation a year ago when I got to a model where I had to insert a bridge that has three arches in it. The way I had it modeled is to use a semi-circle equation that shows like this: r^2=x^2+y^2. Here r stands for the radius of the circle, and so, for our bridge it is half the value of the span of the arches. You can isolate y (the elevation in meters or feet) in the equation and calculate the values for a list of x’s that are bounded between the first and last point of each arch in your bridge. The more you use small steps between x and x+1, the more you get a well defined arch.
