Help,

I'm at the end of my thether !

I have created an airport ( Martlesham Heath in Suffolk, pre war test centre for Spitfire amongst many others) I tried using AFCAD, but could not get rid of the autogen scenery ( FS9 trees and buildings ) within the airfield and on the runway. I then tried an exclude and flatten area using FSSC, but this just got rid of the AFCAD airfield and left the autogen intact.
I then tried adding an exclude area to my FS9 Scenery config file. This got rid of the autogen stuff , but also every other scenery item from FSSC or AFCAD.

What am I doing wrong??? I know I could set autogen to minimum , but this is not a real answer.

OK this is what I have found through massive  trial, much frustration and error.

First of all I was making a mistake when using FSSC . I found that it is really essential to check your destination folder is set correctly every time , before  exporting the file ( It seems to change settings by itself).

Secondly , even if you don't include an exclude area in FSSC the programme still creates one ! You need to go into your Add on scenery airport scenery folder and delete the excl.bgl every time . If you don't do this a large area around any runway created is totally excluded ( no autogen for miles around) If you delete the excl folder, the act of  creating a runway excludes autogen for a reasonable distance around any runway and flattens the area also. If you use the specific exclude feature in FSSC it seems to exclude absolutely everything!!

The way I have now created my grass  pre WW2 airfield is to install a couple of FSSC runways with the textures set to "invisible" ( the grass textures in Fssc don't change with the seasons and look terrible). These invisible runways  flatten the site and get rid of autogen in the immediate area . I ensure that I manually delete any exclbgl automatically created by FSSC remember. I have then installed grass runways via AFCAD ( these are semi transparent and do change with the seasons).

This method is probably not the "correct " method , but it seems to work for now.
