Well, I download these files from the forum but now don't know if they are relevant anymore!If they are not, please let me know since I don't need to be scratching my head over these two files and all the other great scenery design files that seem to have a place in the world.:-hmmm

If you can give a link to the source of those files, so I can see them, I can tell you if they are useful.I'm a little suspicious of them. are current.[link:webpages.charter.net/ludowr/tdfcalc3.zip|TDFCalc3] is useful with FSUIPC during a flight.[link:webpages.charter.net/ludowr/landcalc2.zip|LandCalc2] is also current.[link:ftp.avsim.com/library/esearch.php?DLID=&Name=&FileName=lwmtut.zip&Author=&CatID=Root]LWM Tutorial is still valid, but you should use the newer TDFMacros.inc and TDFHeaders.inc, as found in TDFMacros.zip, listed above, as that has some minor fixes.Dick

Dick,I think I downloaded them from one of your posts!:-lol I attached the files, first is LWMMacros.inc and the second LWMtestfill.asm.

Hi W.Dispose of them.They are older than dirt. :-lol The LWM Tutorial, along with the FS2002 Terrain SDK, are the sources you should now be using.( although that combo will produce a valid BGL ).Dick

If they are older than dirt, I hate to think whay you and I are!!!:-lol
