open .dxf/.dwg with HFSS program

Hi,

I am learning HFSS, and I am using to create microstrips antennas.

I have the microstrip antenna design in jpeg, I have vectorized the picture and I have created the file with extension .dxf, then I have modified something in the design and I am trying to open the document .dxf or dwg in HFSS.

I do : Modeler>import>selectfile ... and I get open the file BUT I can not see the perfect design only I can see some lines...

Why not?

How I can open the file to see the correct design?

Do I need to modified some properties in Autocad before?

Thanks Very much ! =)

Creating useful DXF vector data from bitmap is not trivial. Check your file in AutoCAD or another CAD package. For filled copper area you want to have closed polyline with zero width.
