Just you have to keep in mind that the model must be in AC3D (because of coordinate x,y,z difference): view FRONT view xy --> model side view view SIDE view zy --> model front view view PLAN view xz --> model plan view In order to get this, you must use the following: select All on the left tool box ROTATE after choosing the AXIS and DEGREE You could use if necessary the SCALE fonction. You place the model with the nose on the right side of the axis, which will become positive values for FG, and JSBsim. (don't forget that JSBsim gives values in inches) In AC3D you can read the size in metrics values. After you can adjust in model.xml file -- Gerard _______________________________________________ Flightgear-devel mailing list [email protected] http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
