Import Nastran#

The extension allows users to import Nastran or STL files into AEDT.

The extension provides a graphical user interface (GUI) for configuration, or it can be used in batch mode via command line arguments.

The following image shows the extension GUI:

Features#

  • Import Nastran or STL files into AEDT.

  • Configure the import process with options such as: - Decimation factor for mesh reduction. - Import as lightweight geometry (only for HFSS). - Planar merging for geometry simplification.

  • Preview the geometry before final import.

  • Switch between light and dark themes in the GUI.

Using the extension#

  1. Open the Automation tab.

  2. Locate and click the Import Nastran or STL File icon under the Extension Manager.

  3. In the user interface: - Select a NAS or STL file using the Browse button. - Set the Decimation factor to control the level of mesh reduction. - Enable Lightweight Import to import the geometry as lightweight (HFSS only). - Enable Planar Merge to simplify planar surfaces in the geometry. - Use the Preview button to preview the geometry before importing.

  4. To import the geometry into AEDT, click OK. Ensure that the settings are correct before finalizing the import.

Command line#

The extension can also be used directly via the command line for batch processing.

Supported arguments include:

  • file_path: Specifies the path to the Nastran or STL file to be imported.

  • lightweight: Specifies whether to import the geometry as lightweight (True/False).

  • decimate: Specifies the decimation factor for mesh reduction (float).

  • planar: Specifies whether to enable planar merging (True/False).
