Parameters
|
|
----------
|
|
objs: list
|
|
A list of two objects or shapes of type wire (1st edge is used) or edge,
|
|
or a 2 edge selection set:`FreeCADGui.Selection.getSelectionEx("", 0)`.
|
|
|
|
radius: float, optional
|
|
It defaults to 100. The curvature of the fillet.
|
|
|
|
chamfer: bool, optional
|
|
It defaults to `False`. If it is `True` it no longer produces
|
|
a rounded fillet but a chamfer (straight edge)
|
|
with the value of the `radius`.
|
|
|
|
delete: bool, optional
|
|
It defaults to `False`. If `True` the source objects are deleted.
|
|
Ignored for shapes.
|
|
|
|
Returns
|
|
-------
|
|
Part::Part2DObjectPython
|
|
The object of Proxy type `'Fillet'`.
|
|
It returns `None` if it fails producing the object.
