Hey Alexey,
sorry for the late reply.
The loss of coordinates of course was my fault.
Stupidly chose wrong system for export.
But question2 still is open. It would be a good feature to somehow reduce the model size to just it's points and there coordinates. autocad seems to be quite limited in handling bigger files and it's painful for the client.
I know i could reduce by smoothen mesh, but that's not what i want. I want to keep the good information and have a nice and dense mesh. But i don't need all the faces to be exported as well. They are dumb anyway as far as i realized.
Thanks for your reply.
Was nice meeting you guys at Intergeo in Hamburg.
Keep up the good work
Alex
