Skew Bridge in Hec_Ras

[sujanshakya]

I am modeling a bridge in Hec_Ras. When I skew the bridge and its cross-sections, it showed the error saying "Pier #1 is partially overlapped with left or right abutment on U/S and D/S side that the piers can't overlap with start or end of the bridge opening." Is this because, i used the skew option after placing the piers on the bridge? Or I should have skewed the deck and bridge cross-sections first and place the piers later as piers will be aligned in the direction of flow. Thanks.

When you skew the bridge, it only changes the centerline station of the pier (upstream and downstream).

I guess you should skew first and then place the piers as you say they'll be aligned with the flow.

Thanks, I guess you are right. I did skew the bridge and the cross-sections only, and place the piers as they are aligned with flow.
