**Concept of Parametric Product**

The concept of Parametric products is similar to the concept of Product
Library.

In Product Library the parts in the product had fixed dimensions. Like the top of the table 1
Mt wide and 2 Mt long. But
consider a case where you have to make many similar products just varying in the dimension.

Look
at the two figures below, the two figures A and B are similar. Suppose you are
making many similar cupboards of same design but of different sizes as
shown below. If you use the ordinary product library then you will have to
input them as two products.

But notice that, the dimensions of the parts are dependent on the Height,
width and depth of the cupboard. For example the width of the left door of
cupboard A and B is half the width of the cupboard. It means the dimensions of
the parts are related with dimensions of the cupboard by a mathematical formula.

So if we input only dimensions of the cupboard, and the formula for
the sizes of the different parts, we can automatically calculate the dimensions
of the individual parts by giving the dimensions of the cupboard. This can be
very useful while defining products and than inserting the BOM (Bill of
Materials for the product) into PLUS 2D for optimization.
