    Default 2D Screw Threads - Any easy way?

    Just wondering.

    If you are just doing a 2D representation of a screw thread, is there are easy way to create it?

    You have a Major Diameter, and a Minor Diameter, plus the form of the thread (poss just plain 30' angles?)

    If you draw just 1 tooth (as it were) can you easily create the whole thread?

    Mostly do drafting related to manufacturing. From doing site layouts with proposed updates, additions and renovations to be budgeted and submitted for bid, to updating and changing existing drawings to reflect maintenance and repair/revision work done on site.

    How about just downloading a drawing from McMaster-Carr.

    Thanks for that, but perhaps I'm a bit dim, errrrr, I want a thread form in AutoCAD (a 2D view - not a 3D model) Not sure how a drawing will help, I mean, I can trace around it.

    Unless I'm misunderstanding your meaning here?

    Probably you missed the button for download on the site linked by SLW.
    Select the thread screw you want (type, form, diameter and lenght) then select thecnical drawing (left column) and on the top left corner of the page you will see the download tab (you can choose between 2D dxf or dwg, PDF, Solidworks and also 3D models in various formats)

    Nope, my glasses must be faulty as I still can't see anything in the left column after going thru to a particular thread.

    All I have in the left column is:

    I guess not all products have a technical draw to download.
    Sorry mate

    I just wondered if it was me missing something.
    I've clicked through a few items and not found any drawings yet. So still unsure if it's me being dim, or (as you say) there are only drawings for certain select items.

    But, that to one side, on the making a 2D thread.
    If I draw 1 pitch of a thread, is there an easy way to create extra pitch's next to each other?

    Basically, I'm taking about drawing say 1 box, then using AutoCAD to create another 20 boxes in one long line, all touching each other.

    In a nutshell, I create 3D models from the client's CAD files or design sketches which I then use to produce high quality rendered images. Click on the link in my signature to view my portfolio. I'm always looking for work, so let me know if you need any custom models or renders. :)

    If you need to just create a simple 2D representation of screw threads, try the ARRAY command. Draw the profile of your thread and create the first thread, upper and lower, with the lower thread offset half the distance from the upper.

    Now start the ARRAY command and pick "Rectangular Array".
    Rows = 1
    Columns = Depends on how long your screw will be
    Select Objects Button = Select all the green lines to include in the Array
    Row Offset = 1
    Column Offset = To set the Column Offset, click the "Pick Column Offset" button and then select the two points shown in the image below.
    Angle of Array = 0

    You will end up with something like what's pictured below. You will of course have to manually draw in the half threads at the beginning and the end of the screw.

    Hope that helps.

    Fantastic.
    Many thanks for the excellent explanation. I've yet to use the ARRAY command, and this will be the ideal time to.

    Thanks for spending the time to post such an excellent description.
