Selecting shapes contained in/inside shape

ajk68

Hi,

I am looking for a way to select all shapes contained within another shape.

I have a list of candidate shapes and I want to test to see which ones are inside a polygon shape (in this case an annular gate polygon).

So far I have:

geSelectArea(window_id gate_shape~>points gate_shape~>objType)
gatecont_shapes=geGetSelectedSet(working_cellview)
geDeselectAll(window_id)

I don't really want to select and deselect as this might clear selections that have already been made. Is there a way to do this outside of the graphic editor suite of commands?

Another issue with this is that it selects everything within the polygon (not just a candidate shape). I could filter the list, but given the above issue (selection in GE), it's somewhat a secondary problem.

Thanks.

  • There are several possibilities, e.g. the Layer Boolean Functions, specifically 'dbLayerInside', should do what you are asking. There is also the 'Advanced Boolean Engine' with 'abeLayerInside' as equivalent, which might be more efficient. The manual way reduces to the point-inside-polygon problem known from computational geometry.

    If that selecting/deselecting troubles you, you could also:
    set = geGetSelectedSet(); store current selection
    ;; do whatever you want with the selection
    geSelectFigs(set); restore selection

    Regards,

    I think I'll use your geSelectFigs(set) idea. 

    Using boolean type functions, I'm not sure how I get the overlap of a shape with a layer...
