How do I constrain the center of a circle to an intersection of two lines?

[Dadagda]

Hi-

So I'm trying to draw a circle whose center is right at the intersection of two lines. I tried to draw them at that exact point but it seems that the center doesn't "snap" to the intersection. If I draw the circle elsewhere and later on come back to constrain its center, I can't really find anywhere I can apply constrain on the center of the circle.

I SW I remember we can add a dot at the center and apply constrain on that. What about NX?

Thank you

Constrain the circle center both lines with 'point on curve'

What kukelyk mentioned only applies to if you're creating your curves as part of a Sketch. If you're not creating a Sketch, then (as you would read if you followed jerry1423's link that as long as the two lines actually intersect in 3D space then you can use the Snap Point method 'Intersection' to do what you want. Make sure the 'Intersection' icon is toggled ON in the Snap Point section of the Select Bar and then simply hold your cursor over the apparent intersection of the two lines when you're creating your Circle and the Que/Status line is asking you to 'Specify center point location'. While hovering over the apparent intersection, if the lines truly intersect in 3D space you will see the point highlight and the Que/Statua line will indicate the you've found the 'Intersection - Line of Line...'.
