Thank you for your reply. Enclosed as requested some examples, how the orientation is used as very often in the existing freeware and partly also commercial sceneries of FS2:
A) Airport project with all its objects
- Ground, Rwy & Decals of all Airports based resp. (automatic) generated on fscloudport.com (with exception of the XREF-objects)
- Add. non XREF-objects like hangars, towers, houses etc. alligned with the runway (as it is the case e.g. for the commercial Lukla Scenery)
- Add. placement and orientation of (generic) Helipads at Heliports
B) Single objects (corresponding to the new POI's)
- some objects concerned like large ships, some special buildings, bridges (other objects may already have the correct orientation)
- Note: some objects like huts in the mountain also have a ground-integration resp. adapted (seems not to be supported anymore too)
C) Placement of repetitive smaller objects
- most objects (automatic) placed and rotated using “ObjectGen” like:
Boats and piers, powerlines, lift-stations and -pylons, passenger bridges and other non XREf airport-objects, cell towers, special vehicles, camping ground, trains and much more (f.e. rocks and tents of the base camps of the commercial Lukla Scenery)
