you modeled all this in SketchUp ? (poor bastards .. hehe) 🙂
very cool animation, congrats !!
well, there's no other software better suited to your needs than CE.
did you carefully study the CGA tutorials ? I highly recommend you go through tutorials 1,2,3,6,7,8,9 IN DETAIL.
when you understand these tutorials, you will be able to create stunning cities.
yes, it takes time to learn CGA. It takes you about 3 weeks with 60% of your work time to get into the basics. But once you have those, you will be massively faster than with SketchUp and have a constant modeling quality over the whole city.
let me know if there's more questions after you studied the tutorials carefully, have taken at least 5 hours to read through the crucial parts of the manual and deeply studied the CGA reference.
let me know if you hit roadblocks [ railroad-blocks 🙂 ]
