5. Right-click in the Browser, and select Suppress Features from the
context menu. See the result in Figure 6.45.

6. Save the motor, and close it.
7. When Inventor returns to the fan assembly, save it.
Now, you need to add your machined handle to the assembly. But you fi rst
need to fi gure out where to place it.
Assembly Sketches
In Chapter 3, you worked in the weldment environment, where you were able to
add a machining feature to the assembly that existed only in the assembly. It's
also possible to add features to assemblies that aren't weldments. You can add
sketches to the assembly that are only used as sketches and not converted to
features.
In order to properly locate your handle, you need to fi gure out where the han-
dle needs to be positioned so that it's useful for moving the fan. You could do
this on the physical prototype, but the goal of using these 3D models is to
develop a digital prototype that lets you validate the design and know it's correct
the fi rst time you build it in the physical world.
In a 2D CAD system, you'd assume that the best way to do this would be to
create a layout sketch—and you'd be correct. The question is whether most
