Can you please educate me and help me to understand:
What is the connection between P&ID, Line Lists & Isometrics?
Can I tracenumber of isometrics to be issued in Line List ?
What is ratio of Isometrics per Line Lists per P&ID? (or any other standart ratios?)
What are top influencers on number of Isometrics required to be issued?
Can it be possible be that number of Isometrics required for the project are inflated? Why it may happen?
Do we need to test run PDMS to confirm number of Isometrics?
Thank you in advance!

-Line list is developed using P&ID.
-Iso drawing containing process data should be consistent with line list and P&ID.
-A high level estimate of multiplying the unique line no. found in line list to a factor of 1.4 to 1.5 would give you the rough quantity of isometric drawings.
-Be aware of the quantity of equipment trims which could inflate your iso drawing count and for some reason, some iso drawing need to be produced with suffix added on the main line no. sequence.
