Re:wind silhouette

[Marven]

That’s because the export format (when using text files) is slightly different from the import format. The export format saves all wind silhouettes at once. The import routine only assumes one wind silhouette.
The correct import format is:

221

0.0000 0.0000
-1.8100 -0.0020
-1.8540 4.5700
-0.2730 4.6090
-0.2740 5.3270

The first line specifies the number of points.
The second line is an empty line
the 3rd and nex lines are the coordinates (X and Z, make sure you use a period as a decimal separator)
