I have a drawing with an array of rectangles. overlayed over each one is a smaller rectangle which overlaps the bigger on 3 of the 4 sides. Each of the smaller, and each of the larger rectangles are the same size as one and other. They're all on the same layer, and all the same colour.

 
I need to filter either the smaller or larger rectangles and I had an idea of doing it on the basis of their area, as obviously it's consistant for each size of rectangle. I'm not sure how I might do this?
 
Cheers

I used QSELECT.

are you try "SSX" filter?...
