Circle

Namespace: AlibreScript.API | Kind: Class

The Circle class provides functionality for creating and manipulating circular geometry within sketches and 3D space.

Practical Usage

Circles are fundamental geometric elements in Alibre Design scripting. They're commonly used for:

• Holes and circular features in mechanical parts
• Circular patterns and geometric layouts
• Constraint references for assembly positioning
• Measurement and inspection points

Common Coding Patterns

# Create a simple circle for a hole
center_point = [0, 0]
hole_radius = 5.0
hole_circle = Circle(center_point, hole_radius, False)
sketch.AddCircle(hole_circle)

# Create reference circles for constraints
ref_circle = Circle([10, 10], 2.5, True) # Reference circle
sketch.AddCircle(ref_circle)

# Access circle properties for calculations
circle_area = 3.14159 * (circle.Radius ** 2)
circumference = circle.Length

Properties

Center

Type: Object The center of the circle [x, y]

CenterPoint

IsReference

Type: Object True if the circle is a reference circle, false if it is a regular circle

Length
