We have some x, y start point and some circle radius. We have some engen that can create path from bezier curve points. How to create circle with Bézier curves?

Unfortunately you can not, but yes you can approximate to a circle by using bezier curves.

I've created a "blob" shape by patching cubic Bezier curves together (screenshot below). I'd like to be able to detect the situation where a curve has crossed over either itself or another curve and was wondering if there's a recommended approach or known...

It wont help the function above.
Of course that would help in the case where the parts that overlap are part of different curves.
curves that make up your curve in pairs to see if there is a solution in [0,1].

How would an algorithm work that achieves this goal? EDIT: For clarification: The radius of the circle and the size and shape of the area are arbitrarily given. The area should be covered with as few circles as possible. The circles may overlap.

Of curves then the smallest radius will define the size of the largest circle that can be used.

Hi.
What is the minimum (or suggested minimum) radius for a 6 axle locomotive.(HO)
I have two areas that have 22" curves, and I'm sure these are fine.
I am more concerned with the majority of my curves which are 18"
Thanks-

It is amazing how tight a radius you can get a loco to go radius that a model 0-8-0 locomotive could negotiate.
And then build your loco to go round the curves.

Ok I'm building a 4 lane track on a door and making it portable with Aurora lock and joiner screwed down. I only have 9" and 6" radius curves. Is this going to be too difficult of a track for casual racers?

Is this going to be too difficult of a track in the corners, reversing them so everyone has equal lane length, using only these curves.
I only have 9" and 6" radius curves.
And joiner screwed down.
