I'm trying to see if it's possible to create a polygon and then be able to punch holes through it so that there's an internal surface inside of the polygon that I can use to snap another polygon to. Below there's two layers that overlap each other (Figure 1) and often sit below the layer I want them both to exist at (Figure 2). I want the internal green polygons to be able to snap to a boundary inside of the orange polygon so that they create a single smooth polygon together.
I can technically create these holes with the "tracked Regions" function but the act of doing so converts the orange polygon into a LineString and automatically sets the elevation to 0 (Figure 3). And I need to export as a Polygon and with correct elevation.
(Figure 3)
I also can do the same by turning the bounding orange polygon into a surface (Figure 4) and the using the "Add/Remove Surface Boundaries" function to create these holes, but again, I need to export as a polygon not as a surface.
(Figure 4)
Any help would be appreciated.
Thanks,
Ross
