    Yep, we do this regularly.
    The main consideration we find is the distance between the toes of the welds, on tees mostly. (the butt weld to the branch connection welds) Most Clients have a given minimum distance between the spacing of welds which may or may not differ from the applicable Standard.

    Hi everyone, my 2-bobs worth.

    I totally agree with mtvalla. As both a fabricator and drafter the only thing the fabricator is interested in is a clearly defined Isometric.
    By the time the fab shop receives the AFC drawing all things should be sorted.
    The dimension plus allowance as described above is good as it cannot be interpreted as anything else.
    Isometric drawings need to be as clear as possible with a minimum of unnecessary information as possible.
    Too many times now we see drawings which are very difficult to read due to either unnecessary info or too much squashed onto one page.
    There is no need to have the dimensions of standard fittings on the iso which seems to be very common now. Its only a matter of configuring the iso generation software to the desired output.

    Cheers
