hfss gerber
I've made some 3D designs in HFSS and now want to export them for PCB fabrication. What I had done in the past was to use HFSS -> SAT export -> AutoCad import of SAT -> DXF export -> ADS/Momentum DXF import -> Gerber export
However, this doesn't work very well with what designs I have (the DXFs don't have gaps in the ground planes like they are in HFSS) and other small issues.
Does anybody have recommendations on a better way? Ideally I'd like to be able to manipulate the designs in something like Momentum (putting a few PCBs together on a larger sheet, etc.) before exporting the final result.
Thanks in advance!

And unfortunately I still don't recal the exact thread but it is here somewhere. Spend some time with "search".
The basic idea is that an exported *.dxf captures the portion of a model that crosses the xy plane. Moving the 3D model and exporting successive *.dxf's creates a series of 2D views of the 3D model (HFSS).
I've done this many times in the past; just it becomes very tedious for large models and/or lots of them.
Is there any other alternative apart from HFSS -> Momentum/ADS -> Gerber?
Thanks!
One trick that comes to mind is to record a script that moves the model and then exports a *.dxf and then moves the model again and so on.
That makes the process less tedious and error prone.
Unfortunately, nothing is ever easy. Actually, if you have a lot of layers to export this should give you an easy "automatic" method.
Ansoft Designer will also export gerbers if you have access to it. I usually export a DXF from HFSS, and then import it to Designer. There may be an easier way to import to Designer, but I haven't tried since that method works.
I think Designer is supposed to open HFSS files directly; is that correct?
Unfortunately Designer doesn't work on my machine properly so I can't test that out right now...
Anyway thanks for the suggestions; I'll try a few things and report back.
Best!
I have a problem with HFSS export to dxf.
My structure has a microwave stub (it has an arc). Unfortunately, after exporting it and reading with AutoCad, or ADS, the arc is very simplified - it consists only of 2 lines, so basically it is useless. Is it possible to force HFSS to use bigger accuracy for dxf export?
hey what i have done is to draw the entire antenna in some softwares like coreldraw etc..
but the antenna i dd are normally simple ones with a couple of right angle slots or a U slot..
coreldraw makes the antenna layout easier to draw..
