Hi, I am new to the WMS- CE-QUAL W2. I followed the instructions in Using TINs tutorial to import a bathymetry file, convert it to TIN, and then triangulate the TIN. All measurements are in meters. From there, I followed tutorial #9 for CE-QUAL W2 set up. However, during step 9.2 : branch identification, in the select the "Get lengths and orientation of branch segments tool" I get an error message: could not assign length and orientation for segment XX. Also, it seems there are multiple segments with the same number assigned to them (this was not the case right after creating the segments). These segments though have different areas assigned to them. Looking for help on how to proceed on assigning length and orientation. And in case someone has pointers on more detailed tutorials, and other help, it'll be much appreciated. Thanks
