 However, there are a number of representations of the size of an object, and this can cause confusion.

 ===When do we use size and when do we use scale?===
 There are no hard and fast rules, but usually we will use ''world size'' when positioning and measuring objects on the [[System_Panel|panels]] as this is easier for us to visualise, and use ''scale'' when dealing with the maths behind a component as this is the 'raw' value used by the system. We may use the ''local size'' of an object when calculating its size in relation to other objects in the same group (so we can position one marble next to another without worrying about the scale of the bag).

 The '''scale''' of the bag (its magnification) is 1:1. But its '''size''' is dependant on the number and size of the marbles inside it. In the case of the bag, size and scale are ''not'' the same. We refer to the size of the bag when considering everything inside it as its ''local size''.
 ===World size===
-Now, it is worth noting that although doubling the scale of the bag will appear to us to double the size of all the marbles in it, in relation to each other they are still the same. Following the definition of ''local size'' above (so consider the scale of the object and everything in it) none of the marbles sizes have changed.

 == Scale vs Size==
-The scale factors of an object describes its dimensions without considering any child objects, and as such will not be affected if any other object on the panel changes its location, size or orientation.
+For all its internal maths, Flowcode deals with ''scale''.
-The ''absolute size'' of an object can be thought of as the product of its scale multiplied by all its child scales.
+However, there are a number of representations of the size of an object, and this can cause confusion.
-This can be thought of as the size of the bounding box of the object. This can be read through the API call [[API Panel.Position.GetBox|GetBox]].
+Imagine all objects start off with a size of 1x1x1 (a unit box). The ''scale'' of the objects you see can be thought of as their ''magnification'' from this unit.
-Unlike scale, the ''size'' of an object depends on the children of that object. Though it may be more intuitive to think of size instead of scale, and therefore size is used in the properties pane, internally and in the exposed [[API Panel.Position|API]] Flowcode uses scale, as this is much quicker to calculate and easier to control.
+For example, take a marble. If it starts off at 1x1x1, any size you see is its scale (magnification) from this starting point. Double the scale and you will double the ''size'' of the marble.
