The "drawing cleaning" commands don't work properly for me

[eranUZA53]

I want to clear a drawing, so there are no duplicated lines. Even if the lines only partially top each other.
Plus breaking the lines at all the intersection points

I tried to use the OVERKILL command and a map3D's Cleanup command.

None of the commands work properly.

I read that there is a problem with when six digits after the floating point, the values ​​could be different between the lines. I fixed it and deleted all the values ​​after the floating points, and all number value are integers.

still, there are lines on top of lines after "overkill," and the program does not find some intersection and does not break the lines

Have tried to check mark the option to ignore color, layer, lineweight.... etc  while using the OVERKILL ?

I found close to 550 objects or segements to be deleted when I checked all these options.
