Member Function Documentation

bounding_box()

bounding_box

(

self

)

Returns the axis-aligned bounding box of the Entity.

        Computes the minimum and maximum coordinates of the Entityxs geometry in X, Y, and Z directions.




        .. code-block:: python

# Create a half-sphere of radius 1 cut by the YZ-plane
halfSphere = cubit.sphere(1.0, 1)
# Compute bounding box as a list [minX, minY, minZ, maxX, maxY, maxZ]
bbox = halfSphere.bounding_box()
print(f"Bounding Box: [{bbox[0]}, {bbox[1]}, {bbox[2]}] to [{bbox[3]}, {bbox[4]}, {bbox[5]}]")  # prints [0, -1, -1] to [1, 1, 1]

        @n return type of : std:: array< double,6 >

Returns

: An array (or list) of six values minX, minY, minZ, maxX, maxY, maxZ.

center_point()

center_point

(

self

)

Returns the geometric center point of the Entity.

        Computes the centroid of the Entityxs geometry based on its current position.




        .. code-block:: python

# Create a unit cube (center at origin)
b = cubit.brick(1.0, 1.0, 1.0)
# Check original center
center = b.center_point()
print(f"Original Center: ({center[0]}, {center[1]}, {center[2]})")  # prints (0, 0, 0)
# Move the cube by (1, 2, 3)
cubit.move(b, [1.0, 2.0, 3.0], False)
# Check new center
center = b.center_point()
print(f"New Center: ({center[0]}, {center[1]}, {center[2]})")  # prints (1, 2, 3)

        @n return type of : std:: array< double,3 >

Returns

: An array (or list) of three values x, y, and z coordinates of the Entityxs center.

id()

id

(

self

)

Retrieves the unique identifier of the Entity.

        Returns the integer ID assigned to the Entity upon creation.




        .. code-block:: python

# Create a unit cube
b = cubit.brick(1.0, 1.0, 1.0)
# Get and print its ID
id = b.id()
print("Entity ID:", id)  # prints 1

        @n return type of :  int

Returns

The integer ID of the Entity.
