  subassemblies
 
I just took apart my latest creation and realized that I didn't want to take part some sections. I've often kept certain sub-parts and many copies of the same assemblies.

If ther are some readymade pictures available, I'd draw the subparts on the computer. That way, you can break apart the subparts and use the elements for something else, without losing the solutions earlier found. Simon (25 years ago, 5-Jan-00, to lugnet.robotics)
