Thank you Joshua, this is great help. It can do reasonable roads and lanes, which is good news. It's also really really top-down. I would not mind some perspective but can do without it. The bridge is also fine. They have a Modern symbol set for USD 22, this is well within budget. So, I'll give City Engine a few days until the trial expires, because it certainly is the real deal, but very hard to control. Then, I guess CD3 can do the job. One more question, this was not clear from the description: can it adapt to a given terrain (river/coast layout) and can it generate a city, or do I have to manually draw all the streets?
