I want to conversion some files( such as 3ds, dae or skp files) to cityGML files. Help me please! There is a tutorial the web site
http://fmepedia.safe.com/articles/FAQ/Explanation-of-the-CityGML-format. But it does not update. For instance the document for fme safe 2012 but I use fme safe 2013 or fme beta 2014. And some transformers are not similar between two versions.
