I was building my model by importing (manholes, pipes, outfall and catchments) by GIS gateway; but unfortunately was not completed well, I actually can see the attribute in DB Editor but cannot see the network even I did zoom extend and checked the zoom well? what do you recommend? are you to post on youtube example !!The second issue is the unit conversion; so if for example the exported length for pipes was in "m" but your input is shown "ft" ?!!so; why we can change the output unit and we cannot change the input? why always "for example" the length is in feet? I would work all input and out put in same units; even the DB table shows unit feet.
