Two questions acually.... 1) I'm having trouble trying to find a way to model concrete for the entire industry complex? How did the rest of you model it? and if you did, could you post some pics? 2) My industries are level with the top of the roadbed...but my main street will be 1/4" below that....any ideas on the transition between the industry concrete pad and the asphalt road? If you could post pics, that would be great?
