Hi thd777, I did what you said regarding the rule and apply it to a street and works really good thanks 

Hi, really interested in this City Engine for Vue, I have been playing for while with the Trial but find easy to work with the rules than come with the samples, but find a bit hard to start a city with my own rules is this the case for you guys?   also I notice the python scripting is not available in the Vue CE  version, how limited will be this to create my own style cities?  Can I use the sample Script for my own used? for example I love the ModernStreets rule but not sure hot to import it to my own proyect.  I also have been playing with the 3d MAX Building generator which I found a lot easier to created realistic building models but again is limited to created modern buildings without streets.
