Trace along spline or checking if a circle intersects something

[Est_engine]

I am afraid this is not that I need. I need to check collision only on this red line, not the whole circle. But I think that I found the answer myself. Just spawning box traces along the circle and rotating them in order to them facing circle direction. Nevertheless, thank you for the answer!
P.S. sorry for my English again))

Hi man,
you can use a boxtrace to check a part of the circle at time, working like it was a polygon.
You define the locations in the “circle” and use the boxtrace from point 0 to point1, from point 1 to point 2.
