Get CurveLoop Center point

[Ali.sadeghi.h1994]

Hi everyone.

Does someone know how to get center point of a CurveLoop?

I have a list consists of all openings  Curveloop on a floor and I want to put an instance exactly on center of Curveloop.

Not sure of any direct methods, but what I've done is loop through the curves to add up all of the points, then divide by the number of points. For example, ((0,0) + (0,2) + (2,0) + (2,2)) / 4 = (1,1).

Use an algorithm to find the centre of a polygon:

Thank you. That's a good idea and I have used that and it works well. But There is still an exception in my code that is existing of a curveloop with circle shape in my Revit model. If you have an idea to solve this exception, I will be happy to let me know.

Thanks for all of your guides and I'm glad that you answered my question.
The exception is existing an opening on floor with circular shape and the algorithm won't give the centroid. I need center point of all openings in any form on floors. If you know other ways to get that, I will be happy to know.

Ah, in that case, when you loop through the curves in the curveloop you can check for Arcs or Ellipses and use the Center property to get it.

Thanks for your solutions.

I will try that.
