placement :

If placement is given, it is used.
|
|
|
|
face : Bool
|
|
If face is False, the circle is shown as a wireframe,

|
otherwise as a face.

|
startangle : start angle of the arc (in degrees)
|
|
|
|
endangle : end angle of the arc (in degrees)
|
|
if startangle and endangle are equal, a circle is created,
|

if they are different an arc is created
|

edge : edge.Curve must be a 'Part.Circle'
