It is all about discipline.
Dimensions of 99% of piping items are fixed according to industry or vendor standards so should not be using design parameters.
Dimensions should be fixed in the catalogue.
We still allow variations in design where allowable, Angle, Radius, Height.
You cannot allow designers to change dimensions as he wishes.
If he knows the correct length then so should cats & specs and it should be fixed in the catalogue.
We have previously had one designer on this site wanting to know how to change the length of a valve because the length in the catalogue did not suit his design.
It is different for structural where lengths and widths of many items, like plates, are dictated by the design.
Then the use of design parameters is useful.
