Ah, interesting. I wrote the same tool but with several variations. One thing on this, is you need to show the resulting triangles. That tells people if you are simply modifying the z on verts of one surface, or adding intersecting tris similar to what a tin volume surface does. That Union option is of interest, as how did you handle the edges? The tris would tell me. So this add-subtract tool is useful for modifying drone surfaces that had vegetation, and you decided on some average value to lower by. The thing is, many times you want to blend that lift/lower for some distance. I did tools that blend by distance from edge, central point, and a few other options. Once you can manipulate surface z's, you can also do things like flatten using some pline boundary. We do that for under piles that are temporary, and we don't want to count the volume for. Another key tool is a "composite high or low" surface, which you need when doing remedial volumes. Sometimes the bottom is existing lowered some amount, and sometimes its proposed lowered some amount. thx
