Issue Accessing Setup Properties for Models with Encrypted 3D Components

[chamanth-vct]

Hi,

I am trying to retrieve the details of an AEDT model and the setup information defined within an AEDT file. I use the following code:

desktop = ansys.aedt.core.Desktop()
project= desktop.load_project(file_path)
project_info = project.info
setup_info = project.setups[0].props

The above code works perfectly for standard models. However, when used on a model containing encrypted 3D components, I can successfully access project_info, but the setup_info is empty.

To troubleshoot, I created two similar models—one normal and one encrypted. These models can be downloaded from this link.

Below is the complete code I used to retrieve and print the project and setup details:

import ansys.aedt.core 
from pathlib import Path
import pyvista as pv

desktop = ansys.aedt.core.Desktop() 
file_paths =  [r"C:\no_encryption_model\Project3.aedt",
              r"C:\encryption_model_1\Project3.aedt" ]

for file_path in file_paths:
    print(*"***************************************************************")
    print(f"Opening file{file_path}")
    project= desktop.load_project(file_path)

    project_info = project.info
    print(*"------------------------")
    print("Project Details")
    for key in project_info.keys():
        print(f"\t {key} :   {project_info[key]}")

    setups = project.setups

    for setup in setups:
        print(*"------------------------")
        print("Setup Properties")
        info = setup.props
        if len(info.keys())==0:
            print("\tSetup properties are not available")

        for key in info.keys():
            print(f"\t {key} :   {info[key]}")

    project.close_project()
    
desktop.close_desktop()

Print message as follows:

Setup Properties
	Setup properties are not available

Observations:

• Normal Model:

  • project.info retrieves all project details as expected.
  • project.setups[0].props successfully retrieve setup properties.

• Encrypted Model:

  • project.info retrieves the project details.
  • project.setups[0].props return an empty result or does not provide any setup details.

Question:
Is there an issue with my code when accessing the setup properties for models containing encrypted 3D components? If so, how can I modify the code to correctly retrieve the setup details?

Thank you in advance for your assistance!
