Why Use This Procedure?
The Densities window is used to create your own list of densities, to be used to calculate the weight of different materials that are incorporated in the parts for which you make Preparations.
And later on, in the Preparation procedure, you can use the weight calculation feature for material rows for the material that has been added to this table. Read more about Weight calculation in the Help Function for that procedure.
