It inherits the entire `Arc` class.
|
|
The only difference is that the `closedCircle` attribute
|
|
is already set to `True`, and the `featureName` attribute
|
|
is `'Circle'`.
|
|
|
|
This will result in an arc that describes a complete circumference
|
|
so the starting angle and end angle will be the same.
|
|
|
|
Internally, both circular arcs and circles are `'Circle'` objects.
|
|
|
|
Discussion
|
|
----------
|
|
Both arcs and circles are `'Circle'` objects, but when it comes to the
|
|
Gui Commands, the relationships are reversed, and both launch the `Arc`
|
|
command.
|
|
|
|
Maybe the relationship should be changed: the base Gui Command
|
|
should be `Circle`, and an arc would launch the same command,
|
|
as both are internally `'Circle'` objects.
|
|
|
|
Another possibility is to rename the `'Circle'` object to `'Arc'`.
|
|
Then both a circle and an arc would internally be `'Arc'` objects,
|
|
and in the Gui Commands they both would use the `Arc` command.
