Nice! I think not using the pattern curve command was a good choice. The pattern curve in a sketch also patterns the contraints (I think). I've found out that pattern geometry is pretty fast too, and it seems to be robust as well. Used it to CAD a gear last week.
I should note, this does not include the fact that the tooth curves should be circle involutions and not simple circle arcs. One way to make the points of an involution is to project points out at a 90 degree angle from the radius/perimeter intersection (tangent to perimeter), at intervals which match the projection of the first neighbor to the intersection on the perimeter to the tangent line. Make this like a good 10-15 points in length at equal interval. Pattern this line around the perimeter. You will see involute curve points naturally appear. Use these for your spline control points. Now you have an involute curve and a straight "line of action." The involute curve solution to gears was one thought up by Euler, and it reduces mechanical wear, stress, and failure.
You are right, but involute gear takes at least 30 minutes, and there are already a dozen videos about that. I ran into problem with NX's "Pattern Curve -> Circular", and this video came first for my keywords.

Thanks for sharing that's videos!! Thank you so much

Sir my eye pattern curve command is missing how to bring it back
Ctrl +z.
Next time please include sound, your voice on the background is very important.
Yes
I think there is a completely different way of doing gears.
Yes, it is for nx command learning
