Hey Benson,
So I worked it trough somehow. I came back to my CAD (dwg file) and I exported ONLY the model without a presentation sheet (I am not sure what is it called in vwx cause I am using polish version) and after many trials (I have tried scalling objects but my file is huuuuuuuge and my computer is not enough for operations like this one and it shot down, and as well I tried many scale and units options...) it worked!
So for me the solution was:
scale 1:1 (as the dwg files are usually like that)
units: meter (as I got 50mm where I should have 50m in scale 1:1)
As I am undesrtanding this well now, I hope that now, when I will create presentation sheet in A2 size I will use the scale 1:1000 and it shoud fit? Am I right? or beacuse those are not cm but m I should use 1:100000... (?)
Not sure why vwx suggested mm but I am happy worked it trough.
happy, its not a problem at the moment...
Now I can explore more... and I am spending second day on drawing thousands of stakes to create land model... such a long way before me.
Thank you Benson for support. Honestly, knowing that somebody is around to help makes me feel I can do it somehow :)
I am new, and I am a self learner*... so I will have MANY questions... but I have learned this way many stuff (PS, Illustrator, Premiere, After Effect, Cad, SketchUp, Android Studio etc.) So I hope this awesome programme will help me take my projects to the next level).
*with a lil help ;)
