How do I see the CG boxes for the engine in OPStudio?
Edit the properties for the engine and remove the (obhidden) property. Save and reload the plane. When you are done modifying the CG box for the engine add the property back in and save. Make sure your engine CG box does not overlap any other CG boxes (the original planes had a problem with this) Greg Pringle / Tailslide Make sure your LODs are centered around the origin (0,0,0) coordinate when you export them.. the more you have to move the parts once they get into opstudio the more the FM will change.
