Let’s have a look on another example. For describing a part according to its function, it is always important to see it in the context of the complete assembly (see Figure 9). In our case it is a clamp on a robot arm. We will define the adjustable clamp head in the center (see Figure 10).
Figure 9
Figure 10: adjustable clamp head
What is the function of that adjustable clamp head (Figure 10)? It is fixed at the mounting ring and brings the adjustable clamp finger at its correct position. Well, now that we've clarified the function, how do we start translating it to GD&T?
You see, with answering a few simple questions you completely define a part with GD&T. And Inventor MBD supports you in defining your requirements according to current standards as you can see in Figure 11.

If you continue you can add all required product and manufacturing information in the model (Figure 12).
Figure 12
The Inventor integrated Tolerance Advisor gives you immediate feedback to your annotations. With the face status coloring you see what is fully, partly or not constrained. You can see the result in Figure 13.
Figure 13
And the decisions we made are not only for the head, they are for the mounting ring and finger as well (see Figure 14 and Figure 15).

Start now
With answering just a few questions about the function you can define a complete tolerancing concept of our assembly and bring the information in the 3D-model.
Now some of you might say, this is all terribly complicated! It is like learning a new language. As soon as you understand it, you have a wonderful toolbox to promote a uniform understanding and interpretation among all involved persons and departments. It might look complicated at first glance, but it's worth to learn it. So, what are you waiting for? Start now and describe your next part with GD&T.
