Below you'll see the same bit of routing and the same BOM. Between the two BOM's I don't alter a thing except for the option to 'group pipes or tubes with the same diameter and schedule'.
If you make the total of all SDR11 pipes mentioned then : 4209+1157+210+418+822+1810+180+47+652+177+3+4626+5888 = 20199 mm
If you however let it be calculated by the program then the grand total
is 41233mm. In other words if you just rely on it then one would risk ordering 21m more then need be. I'm all for having a bit to spare but 100% is certainly overdoing it!
Has anyone else ran into this problem?
And yes, I'm making an Rx to send up the chain but I thought it best to give you all a heads-up.
Have a nice one.
