How Dimensions allow us to build Models more efficiently

Dimensions allow you to work with a collection of items without having to repeat calculations.
A Dimension might be:
Widget Model | Model A, Model B, and Model C
or
Sales Region | North, East, West, and South
Dimensions are extremely powerful, time-saving, and improve the quality of your Models.
In the example screenshot below, the Revenues by membership type Variable has the Membership Tier Dimension applied. The Membership Tier has 3 children: Basic, Premium, Platinum.
The Variable has a single formula, Gym members * Revenue per member. The [Auto] suffixes in the formula imply that the Calculation is able to automatically reference the appropriate line of the referenced Variables, which both also have the Membership Tier Dimension applied.
Using Dimensions, you can replace multiple sets of calculations with a single one, without worrying about copy/paste errors.
You can apply as many Dimensions as you like to a Variable.
In the example screenshot below, the Revenues by region and membership type Variable has two Dimensions applied: Membership Tier and Region. Models calculates a value for each combination of the children of the two Dimensions, in this case 6 lines in total.
Models can create summaries of Dimensions easily - you don't need to worry about referencing the correct lines in a Calculation.
To do this we simply create a new Variable with the Region Dimension applied, and reference the Revenues by region and membership type Variable. Models does the rest for us automatically.
In the example screenshot below, we want to show the total Revenues across the North and South regions from the Revenues by region and membership type Variable (see above example).
