Scenproc... Ok, been looking at this tonight and I can basically see how it works. However, I'm not sure it can do what I still would like to achieve, which is to exclude the existing automatically generated cultivation radio masts (i.e. multi-floored buildings) and replace them with my own hand placed versions. In other words, not include a .KML file for exclusion during the scenproc script processing, but rather entries in a .TOC file that would exclude an area within an already cultivated area using lat/lon coordinates I specify.
Does that make sense? Am I asking for the impossible by any chance?
