Thank you pascal you were exactly correct.
It seems the tool you are using to generate the Shapefiles might only produce one flavor of polygon at a time. Be aware that by using the GUIDs provided below one polygon can have multiple attributes. A person could modify the DBF portion of the shapefile. Perhaps forwarding this information to the tool author might allow them to natively support.If you don't delete the file next time the program will append a new polygon to the existing ones. The file is then processed by the BLN2SHP to generate the shapefiles. This program from Jim will generate the shape files for:
For example to move an airport it's necessary to generate two bln one for exclude and one for flatten. For José Maia's LPPM
To produce the shapefile
BLN2SHP.exe LPPM_EX.bln EX
BLN2SHP.exe LPVL_FL.bln FL
then use the shp2vec with -ADDTOCELLS In this case the output is 0502.bgl since it is in Portugal
Problem / feature... that pesky round earth thing.Hi Michael,
I did the new poly with Ground2k4, placed the grass poly at layer 7. This is for the exclude
I then did an LWM mask, and made it a flatten at the altitude I want.
I discovered, however, that the flat isn't entirely flat, there's a 0.1, 0.2 feet diference within the airport. Maybe the round earth problem.
I have the source for the program and it uses the "Flatten + MaskClassMap + ExcludeAG" GUID. I also have only a single polygon per file.It seems the tool you are using to generate the Shapefiles might only produce one flavor of polygon at a time.

If that's the flavor of polygon you desire, great! Just want people to know that it is possible to get any combination of those behaviors depending on the GUID that is used. Seems like I'm seeing posts stating they are creating two polygons where one would do. I'm not familiar with Bln2Shp but it might be nice if the user could specify what they were desiring to avoid editing the Shapefile's dbf file.I have the source for the program and it uses the "Flatten + MaskClassMap + ExcludeAG" GUID.

Please don't disable the default scenery!I'm afraid there are further problems. The FSX default and coastlines are not particularly accurate. At Cardiff, Wales, I have created a more sensible flatten but the default extends beyond the coastline and is not overridden by mine. The only solution I can see is to inhibit 0501 base.
Vector Exclusion polygons don't need elevation (the example does have it because I was lazy and used a flatten Shapefile as a template) - Shp2Vec will ignore it.Ahh, thanks for that Doug. Presumably the polygon height doesn't affect the exclusion so I can just enclose the default AB at height zero?
Hello Blazer. How does one go about creating a VTP 2 Poly? or an LWM flatten? Where can I find Ground 2K. Sorry for the simple questions, but I am relatively new to scenery development and am trying to learn as much as possible. I am designing my own airport in FSX and will need to exclude the autogen trees (everything else has already excluded), and flatten the area, as the terrain is rather hilly. Thanks for your help. RomanHi guys and gals (are there any?),
I don't know if eveybody knows this, if not great, if the do sorry for double-posting.
The only way I managed to flatten the FSX ground was using an LWM flatten in Ground2k. I don't know about SBuild as I do not have it.
Also the only way I managed to exclude the autogen was creating a new VTP2 Poly.
I don't know if it's the only way, if not please post other ways to do this task as I'm sure interested in learning all ins and outs of the FSX engine.
