Make Arc with OSNAP

We can make the arc by determining the position of three points.

The first point is the starting point (1). The second point (2) is a point on the circumference of the arc, the third point is the end point (3)

The steps we need to do:

Ribbon: Home tab> Draw panel> Arc the drop-down> 3-Point

or:

From the Menu Bar select Draw> Arc> 3points

In order for the Arc that we made to be accurate when dealing with other objects, it is necessary to set the object snap contained on drafting settings dialog box.
