I need to make a block that shows different shackle sizes and types. I have an idea of what I want to do for it I just need some advice for how to organize it.



I have cad files for all of the shackles so drawing them and setting parameters are not necessary.  I have a front and side view of the shackles. I have 2 different types of shackles (anchor and chain). I also have 2 different screw types (bolt and screw).
 
I am not sure the best way to go about putting all of these items into one block. I have tried a lookup table, but that failed to work.
 
Any advice would be greatly appreciated!!
 
Thanks in advance.
