I have a question related to this example sentence:
Preparation of Isometrics, bill of material of all lines and supporting details of all lines below 2-1/2" except lines under IBR and get subsequent approval.
From the above:
What are the sizes of lines for preparation of isometrics? Is it for all lines or for lines below 2-1/2"?
Is getting subsequent approval for (a) all isometrics, bill of materials and also for the supporting details or (b) only supporting details?
