    Yes you can make spring and threads in AutoCAD 2004 using thread.lsp & helix.lsp files if you want more information kindly contact me through this email : rgugr@yahoo.com

    Great tutorial! I'm using the principles I learned here to draw a spiral staircase. I now have it complete except for the 1/2" thick acrylic balustrade panels, which I can't figure out for the life of me. My instinct was to draw a 1/2 thick cylinder of the correct diameter and try to use the handrail (helix) as a boundary for slicing the cylinder, but CAD won't recognize the helix for this purpose. Any suggestions?

    Sir,

    I want to draw the thread of a bolt and for that I did draw a spiral with the helix lisp and extrude a triangle with the helix as a path (using ACAD2004).
    The result is that the shape of the triangle is rotating along the helix path.
    What is the trick to keep the triangle parallel to the outside of the bolt?
  • Bryan Adkins · 2 years ago
    Mr Toker, Very Informative and a very direct approach to this problem, I have been wondering how to approach a similar situation I believe this information will apply. On another subject, I have been working with some Autolisp code and have a great deal of success creating a variety or subroutines in a varied area of application. I have reached a dead end and am looking for some example code of how to deal with / Modify Solids with code. Am I confined to only (command "whatever" "" ) approach, can I work with solids from an "entmake" approach assigning 3d coordinates ? Where do I look for an answer to this problem. ,, PS I use a Legal Registered version of Architectural Desktop 2007, is there an online resource from Autodesk that I am not aware of. Thank you very much, Sincerely Bryan
  • Orhan Toker · 2 years ago
    Hi Bryan,

    I'm afraid you can not modify or create solids with standard AutoLISP functions. You have to checkout Visual LISP (vla_xxxxx) functions. Or please ask this question to Muharrem. He's a real Visual LISP expert :)

    sir toker,
    do you have any tuitorial how to make a spring in a curve path?

    Thank you very much

    sir toker,

    we have developed a product to import iges file into autocad, could you please evaluate our software and make some comments?

    thanks

    I type helix into the command line on auto cad 2005 and it doesn't recognise it. strange

    Hello John,
    HELIX command available after Acad 2007.
    How can I download your project and sample IGES files?
  • Kat · 2 years ago
    John,

    You can download 3D spiral autolisp routine from the t'interweb which will allow you to create 2D and 3D spirals in earlier versions.

    Hello John,
    can you help me with lofting error in AutoCAD?
    I have two different cross-sections: one big and one small triangle. When I use lofting by path solid object has correct bounds, like this:
    X = 0.0000 , Y = 0.0000 , Z = 0.0000
    X = 100.0000 , Y = 100.0000 , Z = 100.0000
    But when I use lofting by cross-sections only solid has incorrect bounds:
    X = -0.0010 , Y = -0.0010 , Z = -0.0010
    X = 100.0010 , Y = 100.0010 , Z = 100.0010
    And this error reflect to other operation. When I try to union conus and lofting solid difference in 0.001 units at the edge sometimes cast ACIS modeling error.

    I have followed everything as far as I can tell but when I go to sweep my object I get a message saying 'Unable to sweep the selected object'. What am I doing wrong?
  • Erhan Toker · 1 year ago
    Hello Chris,
    Be sure that profile polyline is closed. And also notice that no crosing or overlapped segments are allowed.
    Hope this helps..

    sir
    may I see how to draw a thread according to rules with ACAD 2004,2005,2006.
  • Henry · 1 year ago
    Hi,

    Where can i find some information about the thread end?? If you really want to draw a real thread, you have to know how make the real shape for the thread end.

    I really need to know that....
  • ryan · 1 year ago
    chris,

    i had the 'unable to sweep the selected object' error as well. turns out that the object i was trying to sweep (in my case a circle) overlapped on itself around the bends of the path i was sweeping along, so i increased the diameter of the bends and the object swept fine.

  • Dominic · 10 months ago
    Hi, I tried your helix tutorial but I have some problem. I put the pattern on position the same on instruction,but when i command sweep,the pattern is rotating and sweep in to path.
