Thanks so much for your help, this works like a charm for FlightGear 0.9.2.

I'm going to use data/Models/MyModels as an example. Step 2 : Inside the data/Models/MyModels drirectory create an xml file called foomodel.xml with the following contents : <?xml version="1.0"?> <PropertyList> <path>foomodel.3ds</path> <animation> <type>range</type> <min-m>0</min-m> <max-m>25000</max-m> </animation> </PropertyList> Step 3 : Create an 3ds model called foomodel.3ds and save it into the data/Models/MyModels directory. Notice that the xml file references the 3ds model file and tells FG that it must be visible from 0 meters up to 25 km. Step 4 : Start FG and fly (or use UFO model and move) to the location where you want to place the model. Open up the property browser in FG and write down the lat, lon and altitude where you want to place the model. (File->Browse Internal Properties->Position) Step 5 : In CVS there is a perl program called calc-tile.pl that works out what stg file a geodetic coordinate falls in. You can get it here if you don't feel like playing with CVS and don't have the CVS branch installed : http://cvs.flightgear.org/cgi-bin/viewcvs/viewcvs.cgi/*checkout*/FlightGear/ scripts/perl/scenery/calc-tile.pl?rev=HEAD&cvsroot=FlightGear-0.9&content-ty pe=text/x-perl Run the perl script in a terminal window passing it the longitude and latitude that you wrote down in step 4. You'll probably have to install perl first if you run on a MS OS's. Example : [EMAIL PROTECTED] scenery]$ ./calc-tile.pl -55.5 30.3 Longitude: -55.5 Latitude: 30.3 Tile: 2039314 Path: "w060n30/w056n30/2039314.stg" Step 6 : Open the corresponding stg file in your scenery directory (in my case SceneryDir/w060n30/w056n30/2039314.stg) Step 7 : Add the following lines to the stg file replacing the parameters with your own : OBJECT_SHARED Models/MyModels/foomodel.xml -55.5 30.3 1000.0 0.00 The format is : OBJECT_SHARED <Relative path to model xml file> <lon> <lat> <altitude above wgs84 ellipsoid> <rotation/heading> Step 8 : Start FG and fly to where you added the model and it should be there.
