Jaguarrh, As an alternative to Procad who seem to just provide a basics course, sketchuptraining.com.au do a couple of more advanced courses; one that covers Visualisation/rendering with Sketchup and a course for producing technical drawings with Sketchup and Layout. The courses focus mostly on architecture and building design but they do cover terrain modelling as well as the use of advanced plugins to extend Sketchup's capabilities. They seem to specialise only in Sketchup unlike the others you mention and if you look at the gallery on the website or follow the link to the Facebook page, they have some very impressive examples. It says that courses are held once or twice a year in Perth, Adelaide, Melbourne, Sydney and Brisbane. Worth a look... Grice

No worries. It did seem like an old saying about trees and the forest would apply, though.
