QElectroTech allows customizing different arc properties:

Appearence

Color: The outline color and the filling color of the part can be defined from a list of pre-defined colors. At the case of the arc part the filling color is None.
Style: The type of outline representation can be chosen between: Normal (Continuous), Dashed, Dotted or, Dots and dashes.
Thickness: The outline thickness (Weight) can be chosen between: None, Thin, Normal, Strong or High.

Geometry

Coordenates: The coordinates (x, y) from the ellipse center point can be defined.
Dimensions: The horizontal and vertical (minimum and maximum or maximum and minimum) diameters from the ellipse can be defined.
Point: The position of initial point and end point are defined as angle of the radius betuen the center and the respective point with the horizontal diameter. The angle value follows the mathematical rules, anti-clockwise for positive angles.

Arc extreme points definition¶

QElectroTech allows defining the arc extreme points from information panel or workspace.
