Area in area problem for overlay analysis?

Hi,

I am not able to produce expected result from the overlay analysis applied on two XFM feature layers.

Test case: Area feature placed inside another area, both are the same polygon XFM feature, a different area feature placed over these two. If I create overlay topology layer, only "outside area" is included, "inside area" is treated as a hole, so 2 shapes are created, not 3 (see attached picture).

Is it spossible to set overlay tool so inside area will be processed also? Version used is V8i SELECTseries 1.

With regards,

  • Just trying to reproduce and understand what you are doing.

    • Are any of these polygn features collections ?
    • What order is the two layers in the intersect form ?
    • What Polygon operation did you use ? Or did you try all of them ?

     

    Usually if you have 2 of the same ploygon feature types, one instance inside of another, you have a 'hole' or donut situation. I would need to understand why you would want a feautre inside of another of the same feature type ( possibly one is a subset of another ??, not sure).

    Thanks !
