Notice that when you added the nested folders, both instances updated,
as when you added the lines. Folder2:1 was created as a child of Folder1:2
because we chose New Folder from its context menu, and Folder2:2 was
inserted into Folder1:2 for the same reason. Note that as with blocks, you
were able to rotate the folder instance on insertion.
Instance vs. Occurrence
To finish with folders, you inspect a few browser functions such as visibility
and property overrides. While performing these exercises you learn the
difference between instances and occurrences.
To override properties
1 In the browser, right-click Folder1:1 and select Property Overrides.
2 In the Property Overrides dialog box, select the Enable overrides check
box.
3 Select the Color check box, The default color changes to red.
4 Click OK.
Note how the entire instance, inclusive of the nested folders is now red.
Also note how the color change did not have an effect on Folder1:2.
5 In the browser, right-click Folder1:1 again, and select Property Overrides
6 In the Property Overrides dialog box, clear the Enable overrides check
box, and click OK.
7 In the browser, right click Folder1:1 ➤ Folder2:1 and select property
overrides.
8 Apply a color override of red to the folder.
