The Arc refers to a circular arc.
Go to Draw > Arc in the main menu to display the Draw dialog box for the Arc. This dialog box has three pages: Arc, Attributes, and Materials, Fig. 1.
The Arc page
In the Arc page the geometrical parameters for the Arc can be set. There are two options: 3 Points and Start – Center – End.
The 3 Points option allows us entering the Arc by giving three points. An arc starting from Start Point, passing through Second Point and ending at End Point will be drawn on the workspace, Figs. 1 and 2.
If Start – Center – End is chosen, the Arc will be drawn starting from Start Point, with the center given by Center and ending at a point determined by End Point, Figs. 3 and 4. The End Point determines the arc aperture angle and the plane where it will be on, so this point could not coincide with the actual ending point of the arc.
Once the geometrical parameters in the Arc page have been set, the Attributes > page can be selected, where the number of segments and cross-section can be set. The wire resistivity and coating can be set in the Materials > page.
