Delete shapes on layerA not enclosed by layerB

MorrisDH

I need to remove all shapes on layerA that are not fully enclosed by layerB.

The dbLayerAndNot marks areas of shapes on layerA that are not enclosed but I'm not sure how to make use of that. And I do not want to delete just areas that are not enclosed. If any part of a shape on layerA is not enclosed I need to delete the entire shape.

BTW: all the original shapes on layerA are polygon types - no rectangles.

  • The following almost works but it leaves partial shapes where the original was not fully enclosed.

    AShapes = setof(shape cvId~>shapes shape~>layerName == "layerA")
    BShapes = setof(shape cvId~>shapes shape~>layerName == "layerB")
     dbLayerAnd(cvId "y1" AShapes BShapes)
    foreach(object setof(shapes cvId~>shapes shapes~>layerName == "layerB") dbDeleteObject(object))
    setof(shapes cvId~>shapes shapes~>layerName == "y1")~>layerName = "layerB"

    I think I can make this work by using dbLayerInside instead of dbLayerAnd, as Andrew suggested.

    yep, this works,

    AShapes = setof(shape cvId~>shapes shape~>layerName == "layerA")
    BShapes = setof(shape cvId~>shapes shape~>layerName == "layerB")
     dbLayerInside(cvId "y1" BShapes AShapes)
    foreach(object setof(shapes cvId~>shapes shapes~>layerName == "layerB") dbDeleteObject(object))
    setof(shapes cvId~>shapes shapes~>layerName == "y1")~>layerName = "layerB"
