What we want is to dimension all valves from midpoint in isometric drawing. Now. both flange-end ball valve and welded three way ball valve are dimension from midpoint, but the dimension of flange-end three way ball valve is too detailed. Please see the screenshot for information.
Dear Shu ZHANG,Thanks for posting your query on plant forum.What I understood from your query is you do not want to have branch dimension in your isometric drawing for three -way valve instead you need midpoint dimensioning for all types of valves.Please confirm if I am thinking in a right direction.Regards,Chanchal Mashalkar
Yes,you are thinking in the right direction
