Hi, I am interested in creating buildings for FlightGear, especiallly for the Montreal area.I just got started with AC3D and have one question. How do you make the model such that the building is the right height and proportion with respect to the scenery that it will be placed in?Is there a scaling factor I need to put in when updating the XML file for this new model? Or does AC3D allow me to create the model with the correct scale (such as 50 feet high, 30 feet long....)?Or is this a matter of trial and error, create the model, use UFO to view it, go back and revise the model...etc.....ThanksSharad

One unit in AC3D or Blender will be 1 meter in FlightGear.
