    Expedition PCB - Polygons, Poly-lines, and tracks.

    david.humphreys@ge.com

      How do I edit polygons/poly-lines?

      How do I transfer a poly-line into a track?

      How do I disable the forced horizontal/vertical/45_degree track constraints?

      How do I edit track vertices to set precise vertex positions?

       

      Explanation:

      Imagine that I am creating a flex-pcb that has a complex, curved profile shape.

      I have a dxf file that describes the required profile.

      I have managed to import the dxf into a drawing layer, and have produced a cleaned-up polygonal representation by tracing around this using a 0.1mm grid (tedious).

      I have managed to discover how to copy this into the 'board outline'.

      I have managed to discover how to copy this into the 'route border', and to shrink this to bring it 1mm inside the board profile.

      I now need to route my tracks along complex, curved, paths.

      I realise that I can copy and shrink my route border to give me the path required for a track that runs just inside the route border.

      So I can create a polygon, with one side describing the path required for my first track.

      I need to convert the polygon into a poly-line, and delete the parts that I don't want.

      I then need to use the poly-line as the route for a track.

       

      Should be simple, I feel, BUT...
