I would like to model some simple vegetation, city furniture and water body in SU and export the CityGML model. Is there a free, working plugin, or some good tutorial who show step by step how to do it manually and setting classes and attributes? I really would like to know from someone who already did it. Many Thanks!
P.S Please guys, I already checked all the links from previous posts about SU + CityGML plugins here, they all point to: discontinued versions, buggy or limited plugins (I do not want to model just building) or paid stuff (200 EUROS).
