I want to export a cst design to work in Microsoft Visio. I want to export a Yagi antenna design,which CST is detecting as mulilayer design. While I select to export in as a DXF file it only selects the element which is in xy plane. In my Yagi design as the driven element is in xy plane it is only selection that one(middle one in the attached picture). How can I export whole antenna design to work in Visio?
