In the latest release of InfraWorks you will find an entirely new way to design roads – Element Based Layout. With this new approach, you can create any combination of tangents and curves, including compound and reverse curves. Simply right click to choose between tangents and curves as you draw. There is even a 3-point curve option for more accuracy and control. Also, you now have the full flexibility to begin or end a road with a curve. You’ll find this way of designing much more effective than the previous PI Based approach, but that approach is still available if you choose to use it.
