Modeling specific metric thread with coil

[rrauenza]

I need to model an internal thread of M6 with a 4m pitch (this is for a PC4-M6-4).  This profile isn't in the thread menu and I don't want to just add it to the xml file -- because then it isn't loadable by others.

I see lots of tutorials on how to make custom threads -- but I don't exactly want an arbitrary custom thread -- I want a specific thread that has specific specifications.   The wiki article on metric threads has a diagram, but I don't know how to convert those specs into a proper coil.  I know it is a triangular profile, but it's also truncated at the top.

For the model, just assume a cube with an M6 threaded hole.  Can someone show me what parameters are required?

Ah, was in the middle of editing, but the edit period expired, and I can't seem to delete the post.

Actually -- I've misunderstood the component's specs.  It's a M6 with 1mm pitch, which is in the menu.  But in general -- how would I model metric threads with coil if those metric threads weren't in the thread menu?

Coil Command has various options, 

Use Triangular section,

Diametre is the nominal diameter from the spec diagram,

pitch is distance / height per revolution.

Extrude cut a cylinder to make the flats and extrude join a cylinder to make the material flats 

Might help...
