Hello one and all .im using fssc in fs 2000 and 2002. ive designed an airport with runways and taxiways, all at 269ft. but the polygons ive used to make the aprons are floating in midair at 400ft or there abouts. is there a sollution to this .im wanting the polygons at 269ft ,the same height as the rest of the scenery . thank you all. merry xmas , and a verry merry 2005.

Don't worry Doug, I think your right.

In the properties box there is an input box saying Altitude. Have a fiddle with that.

The help on that box says that it is relative to the scenery altitude. That could be your problem. And what Doug says about flickering is definatly true.

Late on this one huh? Tough to beat Hagar on a topic, lol.

All is true that Hagar and Dan mentioned. I will give you another hint that I learned when using FSSC.

As mentioned, everything you add is relative to the Scenery Altitude you set off the get go. When adding polys, objects, runways and taxiways, it is always good and strongly suggested to set it's altitude a fraction higher than 0. Say.... .01 or .02. This allows a better display, no flickering and eliminates any potential display problems.

Good luck op with your scenery. It's a lot of work, but fun to learn.
