I have about 200 of the joints shown in picture 1.
The idea when constructing is to have slots pre-cut so the pieces fit together like a scissor, see picture 2.
I could not figure out how to pattern the cuts such that I did not have to do each cut as an individual feature.
I was able to sweep the horizontal cut along the edge of one of the members but was not able to do the same for the vertical cut.
I have attached my model.
