File

File selections have to be in .txt and the format is as described below:

The X part of the 2D coordinate is written in the first column, while the X is written in the second, separated by a space. The next coordinate is found by “enter”. You can add comments to the file using the hash command. Also, you need to close the line, that is the first and the last coordinate have to be the same.

Example:

10.0000;10.0000

10.0000;20.0000

40.0000;20.0000

40.0000;-20.0000

30.0000;-20.0000

30.0000;10.0000

Remember to add the first point at the end to close the shape.

10.0000;10.0000
