As a follow-up to this old thread, it's known that CBUSH elements can be used to connect surfaces with offsets (e.g. the cbush elements can have non-coincident nodes), but is there a rule of thumb on how large the gap/how long the cbush can really be? Like say for example, I'm working on a model that's primarily beam elements, but there's a few joints in particular where I must attach gusset plates. the tubes are 2.x2x0.25 aluminum, and so the offset ends up being 1.25" when the gusset is 0.5" thick.
What if the beam elements had been 6x6x0.25 or even larger? Theoretically, the length shouldn't really matter, but psychologically, using springs in this instance of 3"+ length seems off.
