Hi, I can get a intersection of a polygon and a line simply by intersect tool, but I can't get a intersection of a circle and a line. What's the different?

I realized a circle is not a surface, but how can I constract a circle surface?

You can create a plane with three points of circle, then intersect the plane with line, then to use distance to centre for condition to show point

Got it, Thanks.

Still, why polygons are special?
