Hi all,
I've been using Watercad V8 and there's an emerging problem that all pipe lengths are scaled up 3 times after I exported Watercad file into Epanet. Although the length value performed on each pipeline in Epanet is true but i know that all the epanet pipelines are longer 3 times than their watercad origins because when I export epanet pipelines back into Autocad file, I can see the whole network is larger than the original network. How can i fix this problem, please advice. Tks.
If the difference is 3.28, then it may be a feet to meters problem. EPANET isn't as forgiving as WaterCAD in dealing with units. Are you converting between units?
If Tom's post did not answer your question then it might help us to know what version of the software you're seeing this problem in. The version number can be found by going to HELP > About WaterCAD inside your program and locating the number in the lower left hand corner that may be in brackets. It should start like this 08.11.XX.XX where X are some numbers. If you could also let us know the date that is next to the version number that may also be useful information.
Regards,
Mark
Looking at your screenshots, the pipe lengths are the same in both applications. In WaterCAD they are rounded off, but they are basically the same. Is it possible that you are zoomed in more in one application than the other and that is why they appear longer?

Yes it's exactly 3.28 but how come it happened although i had already set up SI unit as default either in watercad and epanet before I executed the drawing. I've been using Watercad V8 XM and the number is 08.09.165.00. Tks.
Hello Hienvous,
This tool "MAY" work for you. The reason I am saying may, is because you are not on the supported version of the tool. If you can upgrade to supported version you WILL be able to fix the issue very easily.
Run this tool and enter scale factor = 0.3048. You have to scale down, right? Hence factor is less than 1. And 0.3048 = 1 / 3.28084

HTH,
