Python script that behaves strangely

Below is attached a Python script that behaves strangely. The script puts the odds (long long X or Y) of the sides of a polylinea as in the attached image or any other.

If I click the side close to the edge (red circle) puts me exactly share if I click on side in center position (green circle) puts the proportion between one end and the point where I clicked like in the attached image.

Further strange thing is that: I close and then open the item again, drawing a Rhino polylinea, launch the script and I click on a side away from the edge puts the first precise altitude and then returns the first casino.

I wish someone would try to see what happens on other computers.

Ciao Vittorio

GetCurvesAndEdges()

@vittorio, i always get the dimension drawn between the startpoint of the segment and the picked point (S).

ciao,

Hi Clement
I found the error. The below Python script is OK.

Hi Vittorio, i´ve found that this whole script can be written using one line and still works the same:

_Dim _Object

:wink:
