Primitives#
This section lists the core AEDT Modeler primitives that are supported both in 2D and 3D solvers (HFSS, Maxwell, Icepak, Q3D, and Mechanical):
Primitives
Objects
They are accessible through the modeler.objects property:
from ansys.aedt.core import Hfss
app = Hfss(
version="2026.1",
non_graphical=False,
new_desktop=True,
close_on_exit=True,
student_version=False,
)
# This call return the Modeler3D class
modeler = app.modeler
# This call returns a Primitives3D object
primitives = modeler
# This call return an Object3d object
my_box = primitives.create_box([0, 0, 0], [10, 10, 10])
my_box = primitives.objects[my_box.id]
# This call return a FacePrimitive object list
my_box.faces
# This call returns an EdgePrimitive object list
my_box.edges
my_box.faces[0].edges
# This call returns a VertexPrimitive object list
my_box.vertices
my_box.faces[0].vertices
my_box.faces[0].edges[0].vertices
...
Objects#
The following classes define objects properties for 3D and 2D Solvers (excluding HFSS 3D Layout). They contain all getters and setters to simplify object manipulation.

# Getter and setter
my_box.material_name
my_box.material_name = "copper"
my_box.faces[0].center
...
Coordinate systems and geometry operators#
The module contains all properties and methods needed to edit a
coordinate system and a set of useful geometry operators.
The CoordinateSystem class is accessible through the create_coordinate_system
method or the coordinate_systems list. The GeometryOperators class can be
imported and used because it is made by static methods.
Manages the coordinate system data and execution. |
|
Manages geometry operators. |
from ansys.aedt.core import Hfss
app = Hfss(
version="2026.1",
non_graphical=False,
new_desktop=True,
close_on_exit=True,
student_version=False,
)
# This call returns the CoordinateSystem object list
cs = app.modeler.coordinate_systems
# This call returns a CoordinateSystem object
new_cs = app.modeler.create_coordinate_system()
...
Advanced modeler operations#
PyAEDT provides higher-level modeling helpers that implement common CAD patterns and
parameterized workflows. Examples include MultiPartComponent for 3D component
management, Stackup3D for parametric stackup creation, and specialized helpers
such as Coil and Weave for winding and fiber-weave geometries. These helpers
wrap lower-level modeler primitives to offer reusable, parameter-driven operations;
they live in the ansys.aedt.core.modeler.advanced_cad package and are typically
instantiated with the application object.
