![]() This option can be ticked off if you wish to work to elevations.įlattening a surveyor’s drawing is a ‘black-box’ type process where it is difficult to know if any information has been lost or distorted. ![]() The result of this is that you can work around 3D drawings but be safe in the knowledge that the resulting lines are in a 2D plane. when working in plan, it ignores the z-axis, when working in elevation it ignores another axis. ![]() In the McNeel Software, Rhinoceros, there is a simple tick box called ‘Project’ that ignores the invisible orthographic axis when working in a view – e.g. In my opinion, all the information is there in the surveyor’s drawing – we just need to use it in 2D.
