find the center of a circle with python

[synaption]

I made a circle that is tangent to two circles and a point, now I would like to find the center of the circle using python. I know I can just click on it and it will tell me in the python console, but I need to automate this process. Any thoughts?

If it is shown in the Python console, can't you use the commands shown there as well?

If you need more help, it could be helpful to attach the file. We don't even know if you use Sketcher or Draft workbench for the circle.

hi

with object selected in 3D view

Code: Select all

try:
    selectedEdge = FreeCADGui.Selection.getSelectionEx()[0].SubObjects[0]   # select one element
    print(selectedEdge.Curve)
    print(selectedEdge.Curve.Radius)
    print(selectedEdge.Curve.Center)
except Exception:
	print("Oups")

given the name

Code: Select all

selectedEdge = App.ActiveDocument.getObject("Circle") # name of circle
print(selectedEdge.Shape.Edge1.Curve)                 # Edge1 = numero of edge
print(selectedEdge.Shape.Edge1.Curve.Radius)
print(selectedEdge.Shape.Edge1.Curve.Center)

EDIT: 20/04/2021 12h21 Paris adding the code for search radius given name

When you are asking for python help, better to put some code on which someone could work on.

Maybe answer is a matter of a line or two.

But it depends on what you want to achieve.

You made circle how. With scripting or using the GUI?
