You can even replace entire assemblies by fusing the assembly into a single part
to simplify things further; and you can replace an entire assembly with a single
part that will allow the user to still see where the assembly is but task memory
with only one part instead of perhaps thousands. All this happens without com-
promising the assembly's understanding of what components are used to make it.
To make it even easier, you can copy an existing View representation to create a
new LOD representation by right-clicking and using a context menu option to do so.
Creating a View Representation
This is a simple tool to use, but taking a little time to walk through the process
will be well worth the effort:
1. Set the view of the fan assembly to look like Figure 5.35.
2. Right-click the icon for View:Default in the Browser, and select New
from the context menu.
This creates a new representation named View1.
3. Slowly double-click the name of View1, and rename it Fan Drive .
4. In the Browser or in the Design window, select the fan support frame,
right-click, and select Isolate from the context menu.
Doing so turns off the visibility of all other components in the
assembly. It doesn't affect the number of components listed on the
status bar as being used or displayed by Inventor. As I mentioned in
the introduction to representations, turning off the visibility of a part
only helps you see things more clearly and offers some graphic per-
formance benefi ts.
5. On the status bar, note the number of parts that are displayed and in
memory.
6. Under the assembly's Level of Detail folder, switch the Active LOD
to Envelope Suppressed and note the change on the status bar.
7. Right-click the Fan Drive, and select Copy to Level of Detail from the
context menu.
8. Save the assembly.
9. Double-click the Fan Drive LOD.
This removes the housing, duct, and fasteners from system memory.
So far, you've modifi ed the representations of the overall fan assem-
bly. Let's modify the way the fan support frame is shown in the
assembly.
