can extract a edge to a sketch?

[eexpss]

I want extract this preselected edge into a sketch, at same position.

If I draw another new sketch, it hard to align the same position with same radium. So I want just extract (export) it.

hi
use this macro Macro_Repro_Wire (select the wire and launch the macro)

and this macro for convert the wire in circle (select the wire and launch the macro)

Code: Select all

import Draft
from FreeCAD import Base
from FreeCAD import Vector
selectionObjects = FreeCADGui.Selection.getSelectionEx()               # Select an object or sub object getSelectionEx
for selection in selectionObjects:
    for selectedEdge in selection.SubObjects:
        if (str(selectedEdge.Curve)[0:6]  == "Circle"):
            pl = selectedEdge.Placement
            pl.Base=FreeCAD.Vector(selectedEdge.Curve.Center)
            pl.Rotation.Q = App.Rotation(App.Vector(0,0,1),selectedEdge.Curve.Axis).Q
            cercle = Draft.makeCircle(radius=selectedEdge.Curve.Radius, placement=pl, face=False, support=None)

mario52, thanks, it work.

but I got a sketch? or a face? it not a circle anymore. I can not edit as circle. when I edit, I got this edit box.

If you select the planar face next to the selected circle and then create a sketch in Part Design the sketch is attached to that face. You can use external geometry to select the circle. That gives you the center and the radius, which is all you need for a circle.

Yes, I know this. but I can not snap the circle to the external circle. I just can align the center point of the circle.

Select both circles and apply the equality constraint "=".

I forgot this. goooood idea. thanks.

You're welcome.
