17.7 - Parent value inheritance

Many Configuration Models that contain a lot of formulas, could be a lot easier to manage if you knew the following trick. Did you know that the value of a parent Feature is automatically transferred to the child Features. In this lesson, we will go over the logic of this Feature value transfer.  

Parent value inheritance.

For this lesson, we've build a simple Configuration Model. In this Configuration Model, a Length and a Width Feature will send their properties to the parent Feature.

On the parent Feature, a calculated value is set: @length x @width. This will give the parent Feature a value. You can see that the child Features have inherited the Value of the parent Feature automatically because they don't have a value of their own. It is good to know that negative values are not inherited. Only positive values are pushed from parents to children, as long as the child does not have a value of its own.
