Hi all,Just curiosity... I imagine most folks doing XML set the "IsAGL" flag to true. Anyone ever set it to false, and if so, why?Just being nosey :)Thanks,Jim Keir

Hi Jim,I have always left it at TRUE until now. But I can imagine that you would set it to FALSE if you want to place a static balloon at a specific altitude in the air or something like that.For all other applications TRUE is much better of course, as your objects will always match the mesh in that case.

Howdy,I have used both for setting effect altitudes. The odd thing is that neither option solved my occasional problem of display altitude. What's happening is that sometimes approaching the object (a cabin with chimney smoke and fire ring) the effect hovers several hundred feet above the intended altitude. Next time you come around, even in the same conditions (time, season, weather), the problem is gone (or not). That's why I tried the FALSE setting with fixed altitude but it didn't make any difference to the problem!?!Anyhow, that's my experience with that switch.Cheers, Holger

I set it true for planting trees, but false for making hardened helipads.GeorgeEdited: I'm an inveterate liar, I don't know true from false ;)

I have used the isAGLswitch = False in my Panama canal scenery to place the locks on a predefined level, since the water level (as defined by LWM polygons) changes within a short distance and I was not sure, on which part the reference point for the object would fall.osman
