Ground Poly Tutorial

Today’s Fanboy Friday is aimed directly at budding FS scenery developers. A couple of years ago, I did a tutorial for simpilotnet that detailed how I went about doing airport ground polygons at the time. Although it was a popular page, the site hosting it seems to have gone belly-up. After scouring my hard drive, I finally found the original doc & images, so I’ve converted them to a PDF.

If you’ve ever wanted to build ground polys, especially runways, like those you’ve seen in some high-detail payware airports, this PDF shows you one way to do it. Since writing it, Arno Gerretsen of FSDeveloper has added a ground poly wizard to his ModelConverterX utility, so the use of the FS2002 game pack to generate the ASM files isn’t required anymore. For more info on that, head over to FSDeveloper and check out the docs for MCX.

You may find that you have questions after reading this tutorial. If you do, please use the comment box below. Bear in mind that I’m pretty busy these days, so I may or may not have time to answer. You can always get good feedback at FSDeveloper in a timely fashion as well.

    Hi Bill
    my name is Slavi
    – excellent tutorial. I have a question. Why data from ADE (lat / lon / heading) are different to those in MakeBGL.
    Thanks. Regards

      I don’t understand your question. In order to tell FS where to put your runway, and at what heading, you need to know the lat/lon and heading so you can enter that info into MakeMDL for compiling the model.

    Yea, great ! But wait a minute.. it is 2013 and what Gmax and FS2002 game pack we are talking about ? Is there anything for 3DS MAX users ?
    3DS max 2012 and MCX… I read the link of “documentation”.. hmm that is a forum where people are asking questions of their needs..I could’t find any of pdf or doc file unfortunately.
    So is this possible to make a tutorial for newer tools ? I tried out MCX following Arno’s tutorial on youtube, But never ever anything happened. I never seen my work in FSX whatever I was doing.
