Wanting to completely rebuild my favorite airport (Fort Wayne, Indiana...KFWA) from scratch for FS2004 but have no idea where to begin. I need a modeling program for the buildings etc. Freeware only. Looking to maybe even do some of the city around it before its all done...but right now the airport is my concern. Will get into how to do textures etc when I get the buildings figured out. I have experience in CAD style programs...but the ones I use for home design are not exactly FS friendly

Figure the sooner I can get started on the buildings the sooner I will know whether I can pull off a halfway decent scenery package :-/
