Using the NX Plug in “3DCS advanced tolerance stack up analysis” you will be able to make great predictions of what will happen when you manufacture real products that are made up of a number of components. You will be able to see clearly how various tolerance schemes will play out as well as the result of the geometric configurations of the various components. You will be able to see if a design will work or not. You will be able to see if your assembly process will have a high or lo w yield. You will find these techniques extremely valuable. In some cases, you will literally save hundreds of thousands of dollars.
