A Split Plane must be used in this case. I'm glad that Mr Rohmberg got his fills filled, but I don't think it was from Mr. Sherer's advice, which is, unfortunately, incorrect, I just verified it. "Split Planes" are creatures for negative layers (usually power planes), but Mr. Rhomberg was trying to fill a polygon on a positive layer. Polygon fills can overlap. However, if they overlap, sequence of filling becomes important. Essentially, the innermost plane should be filled first, then the outermost. If you have an outermost plane first and want to place a plane contained within it, you can move the first plane to another layer while you place and fill the innermost plane, then move the outer one back and fill it. If the planes intersect but neither contains the other, then I can give no general advice as to which to pour first But with polygon pours, it might be better to split them so that pour is explicit. polygon pours with the same net can overlap without any ambiguity. This is one way that polygon pours are more flexible than inner planes. I think DXP fixes the inner plane limitation.

I haven't tried placing polygons on top of each other for years. I remember placing polygons of the same net over each other in protel98 was pretty bad, it would slow down the machine ridiculously. Though I thought they fixed that in 99? (actually I was very annoyed at protel for this, including a major bugfix in the *next revision* on their software, protel99, but not making the fix available as a patch for protel 98..)

I'd recommend you set it to remove the dead copper, though its not going to make a difference for your current problem.

Re: [PEDA] polygon fill
Interesting, a friend of mine working for another company reported the same problem today. The polygon Plane parameters were setup correctly. We tried to play with the DRC rules. It was the only polygon on the board. Nothing could be done. Any ideas?

You may not be copying, but creating a polygon on a board having an existing polygon. Protel gets confused if you create a polygon which lies within or overlaps another polygon (with a different net name) on the same layer. See Protel's Help topics.

Re: [PEDA] polygon fill
Chris- I had second thoughts. You may not be copying, but creating a polygon on a board having an existing polygon. Protel gets confused if you create a polygon which lies within or overlaps another polygon (with a different net name) on the same layer. See Protel's Help topics. A Split Plane must be used in this case. In brief, the added Polygon is made using the Place Split Plane option; the polygons may NOT overlap, and an "inner" polygon must NOT be fully enclosed by the "outer" polygon. To created space for the "inner" polygon, the outer polygon may be edited to break its outline and move the resulting vertices, to create a hole in the outer polygon.

Re: [PEDA] polygon fill
Hi, Chris- I asume you're doing a Copy of an existing Polygon. After dropping the polygon, in the Properties Box that appears, assing it to Net "GND". It will connect to Gnd after repouring. Alternatively, instead of doing a normal paste, use the "Paste Special" option, checking the box for "Keep Net Name", and when it asks "Repour Polygon" say Yes. N.B: If you're copying from an existing Polygon, the source document from which the original object is being copied MUST remain open until the object is pasted to its new location/document.
