If you are starting to explore setting up constraint based configured products then it helps to start simple till you understand how the models works and then add to it. The first thing you need to do is determine the questions you want to ask the operator that will effect the BOM or route of the product you are building. These questions then might have a list of values the user can select from, in AX these are your attributes. Once you have these then you can use them to make some logic decisions for your BOM lines.

Here is a quick walk through on creating a new product and simple configuration model

AX2012 R3 CU9.
