  Hi there
  
  I have a completed transmission line design created in Altium Designer 18 which I want to simulate in HFSS. Exporting from Altium as a .anf file allows me to import into the Electronics Desktop with all my layer information, dielectric constants etc intact. However, i can't figure out how to simulate in HFSS as Modeller / Import does not accept .anf files.
  
  I can export from Altium as .dxf but then I lose all my layer / materials information.
  
  If anyone can point me in the right direction I will be grateful.
  
  Thanks

  Hi Philip,
  
  Best way to bring Altium files into HFSS and preserve padstack definitions, net names, layer thickness and material properties, etc. is to use ODB++ export from Altium. Then in Electronics Desktop, use menu item File>>Import>>ODB++ to bring it into HFSS.

  Thanks slouie - I tried this a couple of hours ago and found all the materials had become vacuum. I will try it again. Cheers.
