Hello- the Perp OSnap should get that point.

I’m sorry, Pascal. I don’t understand Perp OSnap.

Hello- start Circle, place the center using the Cen osnap to hit the center of the existing circular curve or edges there. Now set the Perp osnap and find the parpendicular point on the smaller arc out to the upper right.

Perfect! Thank you. I’ve been using Rhino for decades and you just taught me a cool trick
