I am doing a personal expansion, of an airport in Wales. But it is part of a UK2000 scenery package. I have no intentions of republishing it, or doing anything public with it. I am looking to extend the airports runway, but there is a fence that I cannot seem to be able to move or delete. This spoils my plans, as although aircraft will ignore the fence, it doesn't help the realism of what I am trying to do. I have already tried sketchup and Model Converter X to no avail. Is there anything else, that people could suggest, on how I can move or delete this impeding fence?
