Thanks Peter and Dimitar

sorry for the English, but I put the figure without color

I take the values of the first list (in red) and associate them with those of the second list (in blue)

You should have a final list:

Point (x = 7655 y = 0.30) from the first list

Point (x = 7655 y = 5.70) from the second list

and then

Point (x = 3.499 y = 0.30) from the first list

Point (x = 3.499 y = 5.70) from the second list

and then

Point (12,499 x = y = 0.30) from the first list

Point (x = 12 499 y = 5.70) from the second list

and then

Point (x = 3.499 y = 6.30) from the first list

Point (x = 3.499 y = 11.70) from the second list

etc.

For these points then insert the wooden beams.

Thanks for collaboration
