Better with the file then.

When you say scale it on, you mean with what tool ? Sorry but I am really a beginner !

Land.skp

Good afternoon everyone !
I just bought a barn on a big land and I will plant a hedge next month on the land limits. I got the .dwg file from the surveyor and I imported it in Sketchup to be able to place my trees on the actual dimensions of the land.
But when I opened the file, all the features are at different heights (z coordinates) that do not make any sense (he told me to only trust the x and y coordinates anyway).
When looking at the top view in parallel projection (instead of perpective), the blueprint looks just fine.
I tried to project all the features on a XY plane/surface I created with the projection tool from the sandbox bar but only some of the features are actually projected and not all of them (maybe there is a limit ?). I cannot figure out why.
I can also share the file if it helps.

Thanks a lot and enjoy your weekend !
