    hmm, do draw a 3D reducing elbow is a bit hard in AutoCAD 2006. if you had 2007, it would be extrememly simple using the LOFT command. i honestly wouldn't know how to do it without a LISP file or something, especially to try and get an exact dia. start/finish. maybe search this site for a Lisp file?

    I've done it by extruding a circle along a path and applying a tpaer to it. I've used this technique to draw reducing elbows.

    How did you do that? On my machine if I extrudse along a path AutoCAD doesn't ask me for a tapper angle...

    if you issue the extrude command, then type P for path before selecting the path it should ask about a taper angle, Type T to enter your angle then select the path and you can extrude a circle around a bend and have it reduce by say 2 degrees as it goes,

    Thanks for the replys,
    I have no lisp experince other than loading a lisp for spiral tube (threads) that I found on this site, which by the way works ... thank-you for that.

    Fuccaro, the link you provided, are the downloadable lisp's somewhere. Or would I copy and paste this, or recopy ??? As you can see I am lost on how use/access the info.

    As far as ReMark's reply I also have not found away to tapper along a path

    Thanks again for the help you have provided.

    yedan,

    Thanks very much ... this works great, exactly what I needed.

    I was entering my reply while you must have been entering yours.

    This is why my second entry may not make much sense.

    Thanks again all

    rvengr:

    Attached is the file you need. download it, then type APPLOAD in AutoCAD to open the Load/Unload Applications dialog box. you'll see "Startup Suite" located on the bottom right, click the Contents button, then Add this file. when you want to use it type CUCONE at the command prompt, this will start the program. have fun
