Programmatically rendering a chain of objects
My knowledge of trigonometry is very limited and prevents me from even reasoning about the problem I'm about to describe.
First I believe it'll help to consider the diagrams below. Please note that in each of the diagrams, the objects are in 3D space.
Object I Object II

The two diagrams above refer to two separate objects in 3D space.
P refers to origin and is meant to show that each object is centered on origin in their respective local space.x denotes a plane (a quad) that is a special connector element allowing for additional objects to be chained together. You can assume that these planes are identical on each object.o is simply a non-connector element that is part of the object.

This diagram illustrates what I'm trying to achieve. Essentially I'd like to draw two separate objects in 3D space and make it look like they are linked/chained together.
To this end I need to calculate object II's rotation and translation in such a way that its connector quad (denoted by x in the diagrams) exactly touches Object I's own connector quad.
What are the operations that I would need to carry out?
I might be just a fool, but if your question was "What do I mean?", I would have little idea with a lot of question marks.
"Programmatically rendering a chain of objects" part is super clear, but the longer description makes things very confusing. Try reducing number of assumptions and just write what you want to do + optionally show assets involved (actual screenshots, no ascii art).
