biglines Posted July 13, 2017 Share Posted July 13, 2017 Vectorworks seems to not understand when I use a looped mainline. Anyone know how to set this up so that the calculations are done automatically as far as flow and pressure loss and sizing? Quote Link to comment
ericjhberg Posted July 13, 2017 Share Posted July 13, 2017 You are correct, the current irrigation tools cannot account for true looped mainline connections which, as I am sure you know, can dramatically lessen pressure loss in a large system. I have put together a quick dummy test showing how VW currently handles looped mainlines and what should be closer based on real rough personal calculations. The following article explains some of the benefits and calculations for looped mainlines, so hopefully VW will catch on with the irrigation tools soon. They are definitely designed for much smaller irrigation installations than many larger landscape architecture practices design. https://www.irrigationtutorials.com/using-a-looped-mainline-for-irrigation/ Looped Mainline Test.vwx 1 Quote Link to comment

Jeff Prince Posted May 22, 2020 Share Posted May 22, 2020 Has any progress been making looped mainlines functional in VW? This is important! I have been teaching myself how to use the VW tools on small projects and had some success. However, I am sensing I may encounter some huge disappointments if I try to use it on my large commercial work. Quote Link to comment
