Arc

An Arc represents a circular arc in AN-SOF.

Accessing the Arc Dialog Box

To open the Arc dialog box:

1. Navigate to Draw > Arc in the main menu.
2. The dialog box contains three tabs: Arc, Attributes, and Materials (Fig. 1).

Arc Tab: Setting Geometrical Parameters

Two options are available for defining the arc:

1. 3 Points (Figs. 1 and 2)
   • Define the arc by specifying three points:
     • Start Point: Starting coordinates (X1, Y1, Z1).
     • Second Point: Second point coordinates (X2, Y2, Z2).
     • End Point: Ending coordinates (X3, Y3, Z3).
2. Start – Center – End (Figs. 3 and 4)
   • Define the arc by:
     • Start Point: Initial coordinates (X1, Y1, Z1).
     • Center: Coordinates of the arc center (Cx, Cy, Cz).
     • End Point: Ending coordinates (X2, Y2, Z2), which may not coincide with the actual ending point of the arc.

Attributes Tab

• Specify the Number of Segments and Cross-Section properties (refer to Wire Attributes).

Materials Tab

• Set the Resistivity and Coating properties of the wire (refer to Wire Materials).
