Hi,
You all may be familiar with the AC14 new option "Place Mesh From Surveyors Data"...
It is a really fast way to create real terrains with just a few clicks. The only problem is that you will need a txt or a xyz file, and not all surveys provide with them, some will give you a dwg containing contour lines at real height.
There is a workaround to use the "mesh from surveyors" option with that dwg file:
It worked for me with more than 12000 points, so it pretty reliable.
just be aware of the amount of polygons generated when viewing on 3D.
Let me know if any clarification is needed.
Regards
Nando

There is a workaround to use the "mesh from surveyors" option with that dwg file:
- 1- open the DWG as an object
2- copy the 3D script to a text editor (just the lines) and save it as txt
3- open the file in MS excel (using commas as separators)
3- use find & replace to replace the LIN_ text with a space
4- at this moment you will have 6 columns
5- take the last 3 and place them at the end so you can have a list of X, Y and Z values
6- save it as a txt , again using commas as separators
It worked for me with more than 12000 points, so it pretty reliable.
