cannot find a good worm gear featurescript

Hello again,
I am looking for a worm gear to worm gear drive on a 12 mm shaft (maybe 10mm) to be a 1:1 at 45 degrees. I want to 3d print this and I only found 2 feature scripts dealing with this.
The first was a globoid worm drive, which is honestly a bit weird. Then I found a promissing worm gear feature script BUT, it is quite unclear as to how it works. When I added it to my document it had one script called rot Trace and one called Envelope 3D. I really have no idea how this is supposed to work so if anybody knows where I can find the instructions OR if anybody has another way to make a nice working worm gear set, please point me in the right direction?

At the moment I reverted back to my extensive Openscad library and make the worm gear there. Then I export it as an stl and import it into Onshape.
I make a boolean with my existing parts in Onshape and I can work with it. It is a bit tedious but it works. If there was a working worm gear feature script in Onshape it would make workflow a lot smoother.
If anybody knows more about it I would love to hear.
Envolepe3d is not a specific feature for making worm gears or any king of gears, it is a generic feature to create envelope geometry, and gears of all kinds is just a single case of the envelopes. In the document where you found that feature should be configured part studios, which create a few types of gears and worm gear is also there. so you don't use the feature directly, just derive part studio that you need and specify configuration parameters
@Konst_Sh
Thank you for your time trying to help me with this. I do not understand how I can get to the document with the feature in it since I searched for the feature script using "add custom feature" ? I will try a search in the global documents to see if I can find it that way.
this should be the original document:
https://cad.onshape.com/documents/306c66ebd346e0f8465b844c/w/eccd3e17bdc644665635430b/e/26b2984fb7f0ffa735e4c520
Ok I see the original document now, thank you.
Where can I find the instructions as to what these variables actually stand for?
Also, if you use it as a derived from this document, you define the gear in this document and then you derive it elsewhere. This means it will change it next time you want to use the feature again but in another document, or am I mistaken?
There are no instructions, those configuration variables names are standard names of gear parameters per ISO i believe. All derives of configured part studios are independent of one another, you define configuration parameters in derived feature dialog and nothing will affect original document
Ok I will give it a try. If I run into trouble with it I will shout out here again and hope you may help me again.
Do I understand correctly that you are the original developer of this document? At least it has Konstantine in the name? I live in Bulgaria, I know a few People with the name Константин.
Anyway thank you again, you have been very helpful.
yes, I'm the author of that document, tag me in this thread if you have a question
I find it hard to impossible grasp, which is undoubtedly me, maybe it is according to ISO but it is certainly not as user friendly as the getriebe.scad by Dr Jörg Janssen.
I will stick with my gear generator in Openscad for now but thank you for your explanation.
