Importing the Model

Import the model from the .dxf file. Create surfaces from the imported model outline.

The geometry for the antenna is obtained from a .dxf file. A .cfx file is also provided for convenience.
  1. Set the model unit to millimetres.
  2. Import single_antenna.dxf.
    Note: The geometry of the antenna is added as a number of polylines.
    Note: There are several ways to convert the polylines into surfaces.
    • Use the Fill hole tool to create a surface from a closed polyline.
    • Create polygons by snapping to the vertices of the polylines.
    • Create a rectangle larger than the extents of the model and Union. Remove the redundant surfaces.
  3. Create the antenna, feedline and other surfaces of the top layer.
