Creating a ground plane

autodeskguest

I have finished creating the board layout except all the GND wires.

What I want is that all the free place on the board will be part of the GND

ground plane.

How should I do that?

    That works, but where do I determinate the distance between the polygon

    and its surrounding tracks and pads.

    If I draw a polygon around text will it leave that area not filled?

     

    Global settings is in the DRC window (clearance tab, wire-via/ wire-wire

    number (Polygon is a wire-fill)). Rerun ratsnest after changing DRC

    settings.

    If you need a bigger clearance for a single polygon, look in the polygon

    properties. Here you can select isolate, but it has to be greater than DRC

    clearance setting, orelse DRC settings will be used.

    Read help/manual a bit on polygons. There are other issues you need to

    know about if you have overlapping polygons, and wire width of polygons

    also matter in how it is filled.

     

    Next problem, I have text on the bottom where the ground plane should come.

    How can I create a clear rectangle around that text. If I create a poly

    around the board the text is still there but completely enclosed.
