Exporting a Design to Ansoft Neutral Format

Supporting your need to work with design files in other formats and with other tools, Altium Designer provides an exporter to export your PCB layouts to the Ansoft™ Neutral file format.

Ansoft was acquired by ANSYS™ and, therefore, the Ansoft Neutral file format is also known after that time as the ANSYS Neutral file format.

Version Support

Altium Designer's Ansoft Exporter exports into version 4.0 Ansoft/ANSYS Neutral file format.

Accessing and Running the Ansoft Exporter

To access Ansoft Neutral file export capabilities in Altium Designer, the Ansoft feature must be enabled for your installation of Altium Designer. This feature is enabled in Altium Designer by default. It can be enabled/disabled after installation.

For more information about changing installed core functionality, refer to the Installing & Managing page (Altium Designer Develop, Altium Designer Agile, Altium Designer).

To access this feature, choose the File » Export » Ansoft Neutral command from the PCB Editor's main menus. In the Export File dialog that opens, specify where and under what name the file is to be stored. By default, the file will be named using the PCB document name and stored in the same folder as the parent project.

The Ansoft exporter extracts component Value parameters from the components on the project's schematics; open the entire Project rather than just the board for the exporter to access these parameters.

With name and location specified as required, click Save. The Ansoft Export dialog will open. Configure further options relating to component naming then click OK to proceed with the export. Once the export has completed, an Information dialog will appear to confirm;  click OK in this dialog.

Importing to Ansoft/ANSYS Tools

With your PCB design exported, you can then import the design into the required Ansoft/ANSYS tool. These include:

  • ANSYS™ SIwave™ (which can also import data generated from Altium Designer in ODB++ format).
  • ANSYS™ HFSS™
  • Ansoft™ DesignerSI™
  • Ansoft™ HFSS™

Notes on Supported Layers and Objects

All appropriate Altium Designer PCB layers and objects are exported to the file, with the following exceptions:

  • All enabled copper, power plane, mechanical and overlay layers are exported.

  • Layer-stack details, including copper thickness and dielectric properties (material, thickness and dielectric constant) are exported.

  • Text strings are exported as objects rather strings, ensuring that their shapes are accurately represented in the ANF file, regardless of the font used in Altium Designer.

If you find an issue, select the text/image and pressCtrl + Enterto send us your feedback.
Feature Availability

The features available to you depend on which Altium solution you have – Altium Develop, an edition of Altium Agile (Agile Teams or Agile Enterprise), or Altium Designer (on active term).
