XS Cutlines Negative

[tglicera]

I kept on getting negative XS Cutlines. What should I do to make it positive? Thanks.

What about the cutlines are negative?

[tglicera]

I tried digitizing the cross section which is the XS Cutlines but after generating it into XS Cutlines3D all the LLeft are negative.

ensure that your flowpath centerlines, in your case the left overbank, are drawn in the right direction. Generally upstream to downstream. If your numbers are negative, try flipping the direction of the flowpath and recomputing attributes.

I was wondering why there is no indicator of flood extent.

You probably didn’t get your model to run successfully. Right click in that window and select “Profiles”, make sure that one or more are selected and press OK.

You also have some issues with your cross section direction. See how that green line zig-zags back and forth? That means some of your sections are drawn from left to right, and some right to left. This should consistently be left to right, when looking downstream, and is pretty important.

In Geometric Editor, on menu Tables click on Reach Lenghts.

What values do you have in this table?
