How many methods do you use to draw an arc in CAD?

Hi, we are completing the arc function in our app, and have coded different methods for drawing an arc, and wanted to know what the most common ones were? For example:

1. 3 points
2. 1 point, centre, angle
3. 2 points, angle
4. 2 points, direction
5. 2 points, radius
6. 2 points, centre

Thanks.

Depends on situation.
Personally, I use them all but, as I said above, depends on situation.
