Translations:Assembly Basic Tutorial/17/en

Now imagine another use case: you have a nice electrical motor assembly consisting of multiple parts, are all moved to the right position. Afterwards you want to create a bigger machine and you need multiple electrical motors for it. What we want is to reuse the motor assembly, the same reasoning as with the multiple body incarnations apply. For simple designs we were able to create multiple parts from one body, however, we can't create a part from multiple parts. Therefore we need another object which can do that! FreeCAD introduces the product object for this. A product is basically a full assembly with multiple parts, but also has a placement property. What does that mean? It becomes clear when we again extend the coordinate system chart with our new product object.
