FIGURE 8.54 Adding an Angular constraint to align the fan blade
10. In the Browser, click twice slowly on the name of the Angular constraint
you just created. When it lets you, rename the constraint Fan Angle .
11. Close the separate fi les for Bearing Cover.ipt , Bearing Cover.iam ,
and Fan Blade.ipt if they're still open. Accept saving any changes if
prompted.
12. If the Update icon is active on the Quick Access Toolbar in the Fan.iam
fi le, select it.
13. Save the assembly.
There was a time when to create a component like the fan blade, people looked
to a system that was built around modeling surfaces.
Inventor is capable of creating extraordinarily complex components using a
mixture of surfaces and solids. It isn't a matter of choosing one or the other but
having the option of moving between tools that let you defi ne elements until the
part is whole.
NOTE For the next exercises, you'll need to download the Grill.ipt
and Power Knob.ipt files from www.sybex.com/go/inventor2010ner .
Save the files to the C:\Data\Parts folder.
Downloading these fi les isn't about saving time as much as it's about focusing
on some advanced tools rather than spending a lot of time using the sketching
skills you already have. Trust me, you'll get plenty of practice with sketching as
you start to translate your 2D models to 3D.
