Okay, I don't understand what the problem is. Can't do that? What exactly can't you do? I don't know.

The problem is that I have to create it with real teeth, with an evolving profile.

I managed to create a wheel model with such profile but the problem is that I probably mistaken the proportionality of the diameters as the teeth are too long and then penetrate into the body of the other wheel.

in the toothed wheel of the link you gave me unfortunately it is not possible to change the primitive diameter and therefore it is not suitable for my purpose, otherwise it would have been perfect.

I attach two of the wheels I have created, as you see if you try to assemble her teeth are too long and so it's not okay.

What do you think I was wrong?
the 4 circumferences I traced are those defined by:

-addendum
- primitive diameter
- basic circumference
-dedendum

the wheels I have to create have all m=1 and therefore z equal to the primitive diameter.

Did you check that the whole of the two trees is right?

Have you tried how I told you before to change definition in the primitive diameter sketch?

I attach a typical pinion that I use with its table setting with the tooth table where you find all the data.
I also did a quick search on the net and herehttp://www.ilcalibro.it/ruote_dentate.htmyou also have formulas for a more refined calculation
I hope the situation is unblocked.

the primitive diameter cannot be changed because it is managed by the relationships. If you go to the parameters and change them, you will see that it updates itself.
