NOTE: Latest version is 0.16 - this stores thread details in the URL field in the properties area so that threads can be identified later.
An issue with the software was that once threads were created, they were particularly difficult to identify - details like pitch, length and thread indexes as well as diameter are complicated and not easily recovered.
So I now record that information by attaching a hyperlink to the entity so that at least this information is attached to the entity itself and can be used later, especially when recording information about a drawing/model or when modifying it with slight variations.
Prior version is 0.15 - This addresses some issues in the thread depth calculation for inside threads.
Hi All,
It's a first version- not even that in fact, as I'm still writing it - but I figure that deperate people might want anything to produce a standard thread. So this application produces an ISO standard thread profile, for any diameter, pitch and length.
And it's easy to use. BTW, Klaus, Can you please ask the forum owners to allow ".LSP" extension files to be attached? We need them for CorelCAD but the extension is not recognized and cannot be uploaded.
So cut out the code ( it's in the next post ) and save as "threads.lsp" in your applications folder...
Instructions.
Note: Please review end of thread to get latest version as an attachment - download and use "appload" to execute.
ThanksDavid
OK, just a note that I just noticed that I got the profile for the inside threads reversed... *sigh*... I'll work on a correction for that.

All fixed now - the profile (after I made this post) should be correct.
Thanks

Please see end of thread for latest version- Thank you -
0.13 Beta is the latest version and seems to work - so should be used for creation of production threads... Sorry I can't attach it as a file. The board still won't accept LSP files.
One trick that has been used before (but I'm not sure I've tried it on this site); save your LSP file. Change the extension to something like JPG. Upload the file and note in your post that anyone downloading it needs to change the extension back to LSP to use it.
But to repeat; I am not sure I've ever tried that trick on this particular site.

Good news: .LSP files are now supported in the coreldraw.com forum (as well as .DWG) for being attached to forum posts.
Best regards,Klaus.
Version 0.13 Beta - This version seems to work and follow all dimensional constraints of ISO bolts. The application will create a face profile and a path for the thread. To complete it, use SWEEP on the face profile ( circle shape ) and select BASE as the bottom of the path. Select TWIST where angle = length / pitch * 360 and then select the path.
It takes a little while to calculate then, but will produce ISO standard threads.
Use appload to load it, then type BOLT to produce an external thread, and NUT to produce an internal thread. NUT threads must be subtracted from a solid to produce the correct thread - ( it's an inverted thread for this reason )
Easy enough :) Post any questions here. As far as I know, this is the first thread application conforming to ISO thread standard. File is threads v 0.13.LSP - Just APPLOAD it and it should work.
Regards
p.s. Klaus, Are you able to edit the above posts to remove the text versions of the app? It's OK to leave them there too, but they are somewhat long and don't serve a purpose now we can upload the files directly :)
