Designer

The PyAnsys Geometry designer subpackage organizes geometry assemblies and synchronizes to a supporting Geometry service instance.

Create the model

This code create the Modeler() object which owns the whole designs tools and data.

from ansys.geometry.core import Modeler

# Create the modeler object itself
modeler = Modeler()

Define the model

The following code define the model by creating a sketch with a circle on the client. It then creates the model on the server.

from ansys.geometry.core.sketch import Sketch
from ansys.geometry.core.math import Point2D
from ansys.geometry.core.misc import UNITS
from pint import Quantity

# Create a sketch and draw a circle on the client
sketch = Sketch()
sketch.circle(Point2D([10, 10], UNITS.mm), Quantity(10, UNITS.mm))

# Create your design on the server
design_name = "ExtrudeProfile"
design = modeler.create_design(design_name)

Add materials to model

This code adds the data structure and properties for individual materials:

from ansys.geometry.core.materials.material import Material
from ansys.geometry.core.materials.property import (
    MaterialProperty,
    MaterialPropertyType,
)

density = Quantity(125, 1000 * UNITS.kg / (UNITS.m * UNITS.m * UNITS.m))
poisson_ratio = Quantity(0.33, UNITS.dimensionless)
tensile_strength = Quantity(45)
material = Material(
    "steel",
    density,
    [MaterialProperty(MaterialPropertyType.POISSON_RATIO, "myPoisson", poisson_ratio)],
)
material.add_property(MaterialPropertyType.TENSILE_STRENGTH, "myTensile", Quantity(45))
design.add_material(material)

Create bodies by extruding the sketch

Extruding a sketch projects all of the specified geometries onto the body. To create a solid body, this code extrudes the sketch profile by a given distance.

body = design.extrude_sketch("JustACircle", sketch, Quantity(10, UNITS.mm))

Create bodies by extruding the face

The following code shows how you can also extrude a face profile by a given distance to create a solid body. There are no modifications against the body containing the source face.

longer_body = design.extrude_face(
    "LongerCircleFace", body.faces[0], Quantity(20, UNITS.mm)
)

You can also translate and tessellate design bodies and project curves onto them. For more information, see these classes:

• Body()

• Component()

Download and save design

You can save your design to disk or download the design of the active Geometry server instance. The following code shows how to download and save the design.

file = "path/to/download.scdocx"
design.download(file)

For more information, see the Design submodule.
