Polygon¶
Declaration¶
- class declaracad.occ.draw.Polygon(parent=None, **kwargs)[source]¶
Bases:
Polyline
A polyline that follows points on a circle of a given inscribed or circumscribed radius.
- Attributes:
- radius: Float
Radius of the polygon
- count: Int
Number of points in the polygon, must be 3 or more.
- inscribed: Bool
Whether the radius should be interpreted as an “inscribed” or “circumscribed” radius. The default is “circumscribed” meaning the points will be on the given radius (inside the circle). If inscribed=True then the midpoint of each segment will be on the circle of the given radius (outside the circle).
Methods
