Looked up a little bit of information on how wood screw threads are cut. Some are "rolled." Have not found much information.

For gimlet point wood screws, from an 1858 patent, with one cutting tool, found here:


http://cool.conservation-us.org/coolaic/sg/wag/Am_Wood_Screws.pdf

(I think the point is that one cutting tool was used, which is shown in three positions. So the tool was
advanced from the right to the left. So for a boolean, the profile would reflect this.

Thanks Brian, also for the added explanation I see now how this single cutting tool does all the work. This will help in making those threads manually. Unfortunately unlike bolt threads there seems to be no standardisation so it looks like it's much harder to make an universal script.

Thanks Martin,

I have script installed, but my question was how to use the script. i.e. do I need to have a cylinder model and selected prior to using the command?

Update: I just figured it out. Thanks for such a cool script!

Hi Michael,

glad you figured it out that it's a lean-back-and-watch sort of script :)

Hi Martin,

You've done a great job on the script, Well done!!

regards Colin

Hi Martin,

WaitForDialogDone will return false if the cancel button was pushed.

So you can do something like (example here taken from Rebuild.js) :

	if ( !WaitForDialogDone() )
		return;

Under normal circumstances where a command just has one factory you can just not call factory.commit() if you want to cancel and any objects that were shown previously from calls to .update() will be automatically cleared out.

But if you've previously called .commit() on any factories, those will be considered complete at the time of the .commit() call so you actually may not want to call .commit() on any ones that are meant to be used for temporary calculations.

Thanks Colin!

Many thanks Michael, that help was neccessary. I didn't think of the WaitForDialogDone() function to actually return a boolean value. I thought it just waits and then continues.
I will use

if ( WaitForDialogDone() ) makeExternalThread();

in the next update of the script.

I attached a further optimized version of this script to the first post of this thread.

- The Cancel button works now correctly
- The thread length will no longer be automatically corrected to get full turns
- A rebuildcurve factory for the profile can be found in the script if someone wants to experiment. I didn't get it to work.

Thanks for the effort. Will test it later today when I got back from work.

Peace,
Rich_Art. ;-)

Will your script thread ready cut holes like those that are required for this model ?

Martin

Hi Martin,

all the holes outlined in yellow need a thread? Just make a thread tap http://moi3d.com/forum/index.php?webtag=MOI&msg=5473.1 and start cutting almost like in real live but without grease. Enjoy.

Hi,
when I open the script, there are no fields for entering the length.

When I try to execute the script, I get an error saying:
"Runtime error in Microsoft JScript:
Illegal procedure call or illegal argument
Line 148 Column 1:"

I downloaded "makeExternalThread-Oct-17-2012.zip" and my MOI version is Version 2.0 May-27-2010

What am I doing wrong?

Hi Spunkhart, most likely the script is set up to run under V3, which uses a different engine for the HTML UI and the scripting part.

You can get the current v3 beta here: http://moi3d.com/beta.htm

Most of the people doing scripts and such are running the current v3 beta and not doing much stuff with v2.

Hi Michael,

that does the trick.
Thank You.

Iwant just to say I am experiencing the same problem ( I hadn't when using OSX...) on a notebook, win XP sp3

Hi Fabri,

> Iwant just to say I am experiencing the same problem

Are you using MoI version 2 on the notebook? I think this script needs v3, you can get the current v3 beta here: http://moi3d.com/beta.htm

- Michael

Yes I am running version 2 because notebook it is not mine… (my wife…) and I am really scared when installing/uninstalling some software under Windows…
I gave up. I like best to use MoI under OSX; less troubles; I hope…
However both files didn't work (the older and the younger). I feel there is some problem about interpreter files in Windows.
Thank you

Hi Fabri,

If I remember right, both of those (the older and the younger) require MoI v3 in order to run, you just won't be able to run them using v2.

There isn't really any reason to be scared of installing the v3 beta, I mean it's just a newer version of MoI with more stuff in it, if you're using v2 it just means you're using old stuff...

- Michael

"""""and I am really scared when installing/uninstalling some software under Windows…""""""

The install is pretty much "standalone", which means it doesn't require anything special about windows. It will install in pretty much 6 seconds.

Just go for it!

Wrote this script for myself. It's a rewritten version of the Martin's script.
