Creating holes in Polygons

    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.

    Original Polygon1(Figure 1)
    Original Polygon2
    (Figure 2)

    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.

    Add Surface Boundaries
    (Figure 4)

    Any help would be appreciated.

    @Ross Bichener What software are you using in this case?

    Got it. You're probably best then to post this question in the Trimble Business Center Community. Unfortunately, I can't cross post this - you'll have to do a copy/paste.
