OSTexo,

I also thought Michael would have pitch in but I guess he's buzy with the new beta release, it's perfectly fine with me.

I appreciate your tutorial and your answers, if it works fine for you why change anything. But it could be a bug also, I just find having to do this kind of extra step is not very "MOIish" to say the least.

By the way, I happen to have an old Machinery's Hand Book 23 revised edition page 1481 "screw design profile" that I could send you if still needed.

Thanks for your time,
Felix
