I have seen tubing 'blue prints' where the depiction was a straight piece of tubing, however along the length of the tube there were notations of a change in the coordinate system. These would be the same as the angle and direction that the tube had to be bent. I suspect there could be 'view AA' notations and a table.

Just an easier way to draw the print, and perhaps there was a master tubing print on-file that the draftsman started with and just had to add the total length of stock to start with and the bending details, which produced a unique part number print.

In my first experience with this print format at least we had a full side piping diagram and a stack of plumbing, which was clearly not straight. After a few minutes it was painfully clear what was going on.
