Ring angular demand

Figure 5 Examples of more complex ring structures ring angular demand.

What is the angular demand of these ring systems ... 

The purpose of the analysis phase is to perceive the properties of the structure and create the drawing strategy that will be used in the assembly phase. The assembly phase will then be a relatively mechanical execution of these instructions. This division simplifies the logical solution of the problem, as modular reductions will do. More importantly, as discussed earlier, it is necessary to design ring systems before they are incorporated into the rest of the structure so that their angular demand may be assessed. 

The ring system represents a more or less fiat board with a space-demanding angular substituent in the 3-position.
