Hi Rastar, The different construction method is a good suggestion and will be included in the next patch. The method is already written into the system for automated road construction via script it just hasn't been enabled for the editor. I'm a bit hesitant to enforce further mathematical restrictions in addition to the road grade enforcement because there are several scenarios, such as bridge creation, which require a lot of freedom. Maybe we could implement this and have it as an option to toggle on and off for the road or sections of road. Here's a poorly drawn image to illustrate how to create a road which doesn't cut into a hill: http://www.microgsd.com/images/TS/TS9.png We've had a lot of issues on MAC. Not sure why. To solve the issue, shift-click and accomplish the same thing as ctrl-click. Sorry about that issue. Bottom line is that the Unity editor does not function the same on PC as the MAC and Road Architect was developed on the PC. It's on the list to fix. Thanks for the comments and let me know if anything else comes up!
