Find intersecting shapes (polygons)

I am trying to return a list of all intersecting shapes on a specified
layer based on one shapes list of Points, I have used the function
below for rectangles, but I need something for polygons. Is there a
"find overlap function" based on shape~>points vs. shape~>bBox? I have
run the chop command on all shapes to convert to rectanges, but not
all shapes can be converted, and I can't do an all shape merge due to
speed issues.

dbGetTrueOverlaps(cvTemp shape~>bBox list("metal" "drawing"))

thanks in advance,

 

You'll need to fracture the polygon first, then get the overlaps of each rectangle.

 

And you can use dbLayerTile() to fracture the shape...

You'll still have a problem with non-orthogonal polygons, but a bit of
post-processing of the matches could help you to filter out any false hits...

Andrew.
