    2D? I'm assuming you'll be drawing a double line representation (showing the true O.D. of the pipe). Go find yourself some pipe fitting symbols to use. This will make the job of inserting things like elbows, tees, flanges, reducers, etc. much easier.

    Specific what? Symbols?

    Are you drawing in imperial or metric units?

    3D? You'll need to develop or buy some 3D fittings and learn how to work in different planes by manipulating your UCS.

    abc_123,
    Welcome.
    I have many years experience in piping design and might be able to help you with your 2D (only) piping questions.
    Start with http://www.spaug.org/LISP_Index01.Html for Russ Steffy's Pipe.LSP

    There is one change you need to make to to Pipe.LSP.
    Change Line:
    Code:
    "WN_2x150""SO_2.5x150""WN_2.5x150""SO_3x150""WN_3x150"
    To:
    Code:
    "SO_2x150""WN_2x150""SO_2.5x150""WN_2.5x150""SO_3x150""WN_3x150"

    Wouldn't it be helpful if we knew what units the OP will be using and what specs he/she will be following?

    PIPE.LSP has option for Drawing Units (millimeters or inches).
