I've spent 3 hrs placing objects around the 3 runway WW2 airfield I'm cobbling together.   I ended a check flight to see how it all looks, but when starting FS9 again after a 20 minute break, for another check flight the runways have vanished.  I took off & looked back they started to apprear. They slowly vanished on getting closer when landing.  I'm assuming a graphics problem but that's a guess.  Can anyone hazard what it might, be along with a solution?  I've checked other airports & they seem OK.  I'm using Afcad 2.21 & Instant Scenery & save afcad changes frequently.  Ummm.....? 

I don't use Afcad much, (at all really) but it sounds like it may be an elevation issue? Any mesh installed?

Opa, I second your thought. 

Whenever any new major 'construction' job starts, you always see land clearning (excluding), and bull dozers (FSFlatten), getting the ground to a precise level.  That is unless you want that retainage pond in a certain place.. but then you can add that with AFCAD.

I too, use Excbuilderv2, and FSFlatten, before I start up AFCAD for parking and Abacus EZ-Scenery for buildings.

Oh dear....I posted after 30 mins of playing around in sheer frustration but it's oeuf sur mon visage 

Yes it's a new one & all's gone quite well until this problem appeared.   Thanks for the flatten tip (I'll get for further jobs) but you're right - it's an elevation issue.  I redid the tower view altitude & it wouldn't take.   I noticed the airport reference point elevation was 0 so changed it to the value I saw in Map.......I didn't put 2 & 2 together.  I've changed the reference point value back to 0 & the runways are visible.
