and find that they conflict with an object which exists in the main scenery?
I've added a Wind Turbine and it's now in the middle of a building (which is not an added object, but part of the base scenery - at least it does not exist as an object here https://scenemodels.flightgear.org/map/)
It does look fairly stupid and obviously I can move it - just wonder whats the 'normal' solution?
