Yes, well, not having geometry is definitely an issue.
But, be aware using 0mm dimensional constraints is not a good practice. In fact, it will most likely bite when you least expect.

I'm assuming you are referring to the places I connected the rectangles to the construction lines? Out of interest, how might that bite me and what is the proper way to accomplish the same thing?
Constrain one vertex to the construction line with constrain point onto object,
