It is not necessary to use the "intersectLayers" method, because that
merely does what multiple "addPolygon" calls do. Each layer in a
"PolyMerge" object is automatically merged into a small number of
complex, nonoverlapping polygons. So simply call "addPolygon" for all
the Poly objects on a given layer, and then pull the results with
"getMergedPoints".
If this still doesn't work, then be sure that the transformations are
right. The "Quick" module has to be careful to orient everything
properly before comparison because of the hierarchy.

I have somewhat found a solution to the problem listed above and
finished the SPACINGE rule for the DRC. However, it still creates a
false-positive flag for a metal-poly contact node because it does not
merge the node metal with the arc metal connected to it. I'm currently
working in the Quick.java file to implement a merger of the two
polygons when they are being read in the DRC. After searching through
the java files, it seems that electric has the capability to merge
these polygons before the DRC check, but I am having difficulty
locating what specific functions need to be called in order to merge
the two before the check. In the "if(edge)" portion of the checkDist
function in Quick.java, I have added this code so far, but it does not
seem to transform the polygons. I think I need to set a polygon to the
newly generated values and continue from there? My added code is below:
PolyMerge merge = new PolyMerge();
merge.addPolygon(layer1,poly1);
merge.addPolygon(layer2,poly2);
merge.intersectLayers(layer1,layer2,layer1); //attempting to combine
the new layers into one?
List<PolyBase> polyList = merge.getMergedPoints(layer1,true);
...
I tried using the min/max X and Y values to hard code exceptions for
nodes, but it still creates too many false positives. I had several
views on my last post, but no help. Hopefully someone can point me in
the right direction for this one? Thanks! Let me know if anymore
information is required.
