Modeling: Extruded plate with cut operations#

As seen in the Rectangular plate with multiple bodies example, you can create a complex sketch with holes and extrude it to create a body. However, you can also perform cut operations on the extruded body to achieve similar results.

from pint import Quantity

from ansys.geometry.core.sketch import Sketch

Define sketch profile without holes#

Create a sketch profile for the proposed design. The sketch is the same as the Rectangular plate with multiple bodies example, but without the holes.

These holes are created by performing cut operations on the extruded body in the next steps.

[2]:

sketch = Sketch()
(sketch.segment(Point2D([-4, 5], unit=UNITS.m), Point2D([4, 5], unit=UNITS.m))
    .segment_to_point(Point2D([4, -5], unit=UNITS.m))
    .segment_to_point(Point2D([-4, -5], unit=UNITS.m))
    .segment_to_point(Point2D([-4, 5], unit=UNITS.m))
    .box(Point2D([0,0], unit=UNITS.m), Quantity(3, UNITS.m), Quantity(3, UNITS.m))
)

modeler = launch_modeler()
design = modeler.create_design("ExtrudedPlateNoHoles")
body = design.extrude_sketch(f"PlateLayer", sketch, Quantity(2, UNITS.m))

design.plot()

Define sketch profile for holes#

Create a sketch profile for the holes in the proposed design. The holes are created by sketching circles at the four corners of the plate. First create a reference sketch for all the circles. This sketch is translated to the four corners of the plate.

[3]:

sketch_hole = Sketch()
sketch_hole.circle(Point2D([0, 0], unit=UNITS.m), Quantity(0.5, UNITS.m))

hole_centers = [
    Plane(Point3D([3, 4, 0], unit=UNITS.m)),
    Plane(Point3D([-3, 4, 0], unit=UNITS.m)),
    Plane(Point3D([-3, -4, 0], unit=UNITS.m)),
    Plane(Point3D([3, -4, 0], unit=UNITS.m)),
]

Perform cut operations on the extruded body#

Perform cut operations on the extruded body to create holes at the four corners of the plate.

[4]:

for center in hole_centers:
    sketch_hole.plane = center
    design.extrude_sketch(
        name= f"H_{center.origin.x}_{center.origin.y}",
        sketch=sketch_hole,
        distance=Quantity(2, UNITS.m),
        cut=True,
    )

design.plot()

Close the modeler#

Close the modeler to free up resources and release the connection.
