Polygon troubles

autodeskguest

My design has two polygons, so far, both named GND.  Ratsnest filled in

the first one but adding another resulted in an error from Ratsnest:

"Signal GND contains an invalid polygon."

 

The two polygons do not touch each other.

 

I am stumped by this.  Any idea what I am missing?

    Hi John,

     

    An invalid polygon means that two of the line segments making the outline

    of the polygon cross over each other.  This usually happens at the corners

    of complex shapes.  Go to each corner, zoom in, and drag out the corner

    until you find it.  Sometimes, it's easier to simply delete and draw

    again.

     

    Cheers,

     

    James.
