Command line extension launch

Every extension can also launch the extension user interface from the terminal:

SET PYAEDT_DESKTOP_PORT=50051
SET PYAEDT_DESKTOP_VERSION=2025.2
python.exe path/to/pyaedt/extensions/project/import_nastran.py

The available arguments are: file_path, planar, lightweight, and decimate. You can obtain these arguments from the help with this command:

python.exe path/to/pyaedt/extensions/project/import_nastran.py --help

This code shows how to pass the input file as an argument, which doesn’t launch the user interface:

export PYAEDT_DESKTOP_PORT=50051
export PYAEDT_DESKTOP_VERSION=2025.2
python.exe path/to/pyaedt/extensions/project/import_nastran.py --file_path="my_file.stl"

Finally, this code shows how you can run the extension directly from a Python script:

import ansys.aedt.core
import os
from ansys.aedt.core.extensions.project.import_nastran import main

file_path = "my_file.stl"
hfss = ansys.aedt.core.Hfss()
# Specify the AEDT session to connect
os.environ["PYAEDT_DESKTOP_PORT"] = str(hfss.desktop_class.port)
os.environ["PYAEDT_DESKTOP_VERSION"] = hfss.desktop_class.aedt_version_id
# Launch extension
main(
    {
        "file_path": file_path,
        "lightweight": True,
        "decimate": 0.0,
        "planar": True,
        "is_test": False,
    }
)
