Is it possible to open it directly ? As it is the case in a CAD software ( i.e. Archicad).
I proceeded as follows (cumbersome): 1- I copied all Navigator's elements from one to other; 2- I imported the workspace from one to other 3- The terrain appears as "unknown texture" 4- I tried laywer=>terrain=>window "terrain" ,etc. but it did not fit properly. I could manage to make it fit, but I guess there is a trick somehow to make things easier. Am I wrong ?
