SIW structure PCB design problem

Hi all.
I have a SIW structure(simply a structure full of vias) in HFSS and want to print it on board.
I think I should convert it into an altium supported file.
the problem is, when I do that the vias wil be converted to arcs in top layer.
Is there a way that I can save my time or I should paint all the vias in altium again?
thanks

Hey

did you try exporting the HFSS into a DXF file?

I exported to HFSS, and imported in ADS Momentum my SIW structures. You should be carefull, in Momentums vias are not more circles but polygons, so you might need to redraw them (it takes time, I know), or you I did this also in the Circuit Cam from LPKF before prototyping.
