MINI INVENTOR FILE FORMAT - quick notes

#Inventor V2.0 ascii
#
#  The first line of the file must be the one above.
#
# Any number that appears in the description below is a "default",
# except those in Coordinate3, IndexedFaceSet and FaceSet, where
# they appear just as an example.

# The entire model should hang from a separator node.  
# They can be used to group a set of children together.
# Separator nodes cause any transformations or materials that hang
# from them to be ignored by nodes that don't hang from them.

	<child1>

# Groups are like separators, only transformations and materials
# within the group apply to all nodes to the right of, and down 
# from, the group. (Depth first traversal, from left to right)
