5 In 3ds Max, choose File > Open and try loading the file you just copied
from the \autoback folder.
If it opens, save the scene and rebuild what you lost in the last five
minutes.
If you'd like to adjust the Auto Backup settings, you'll find them on the Files
panel
on page 7541 of the Preference Settings dialog, available via the Preferences
command on the Customize menu.
Fixing Boolean Problems
Boolean operations are a powerful addition to your modeling toolbox; however,
they can sometimes give strange or unexpected results. The Boolean button
is found on the Create panel in the Compound Objects list; it allows you to
join, subtract, intersect, and cut objects. Following is a list of problem scenarios
and steps you can follow to fix them.
TIP The ProBoolean compound object on page 774 represents a significant
improvement over the legacy Boolean compound object in a number of ways. In
most cases, it's highly recommended that you use ProBoolean rather than Boolean.
TIP Before performing a Boolean operation, you should save your scene or use
Edit > Hold. That way, you can quickly recover should anything not appear as
expected.
Problems and Resolutions
Boolean Objects Disappear
If you mistakenly perform an Intersection Boolean operation on two objects
that look like they intersect, but actually don't, you can end up in a situation
where the object completely disappears. In the Operands group, you see both
your objects listed but nothing on-screen.
1 Click the Undo button to retract the Operand B selection.
2 Right-click to exit the Boolean operation.
3 Verify that the objects intersect by checking them in two viewports, like
the Top and Left.
4 Click Boolean to turn on the operation, and click Pick Operand B.
