Overlapping S-Objects

[cgraves10]

I am trying to create an s-object to make interlocking barriers used at kart tracks, the only problem is I cannot get the last and first to overlap each other like I want them to and there is a large gap inbetween them, is there a solution for this or am i going to have to place the object manually

I have the same problem. If the space before and after it is accepted as negative values ​​could solve. Maybe next version.

Maybe each block object could contain the start of the next block, so each object would look something like this:

You'd also have another object where the red and white are swapped.

edit: Hang on, have you tried using a negative 'offset'?

I think the calculations should eliminate the negative values.
R. Soul: your idea works but the point of rotation and the union will no longer be the correct
