CREATE ARC
This function allows the user to generate circular arcs. There are three types:
1. CENTER AND RADIUS
Define a LCS. See Section 2.5, LOCAL COORDINATE SYSTEM. The center of the arc will be at the origin, and the arc will be in the UV plane of the LCS.
Enter the values in the ARC PARAMETER dialog window. See Figure 5.1.3.

2.TANGENT TO 2L
This function allows the user to create an arc that is tangent to 2 lines.
Select two intersecting lines. See Section 4.5.1, PART/ADD LINE, for more information on selecting lines.
Enter the radius in the RADIUS OF ARC field.
3.Create by THROUGH 3 PTS.
This function allows the user to create an arc through three non-collinear points/nodes.
Select three points in Figure 5.1.2, and refer to Section 5.1.1. When the third point is selected, the arc and its center will be generated.
