The Edit UVWs dialog (page 1–888) menu
bar provides access to a number of important
editing commands. Some of these commands
are replicated on the dialog toolbar and the
Unwrap UVW command panel; othe rs, such as
the Mapping, Stitch, and Sketch tools, are available
only from the menus.
Tip: Several commands are not available in the
editor interface by default; you can use the
Customize User Interface dialog (page 3–792) to
add them.
Interfa ce
File men u
Loa d UVs —Loads a previously saved UVW (texture
coordinates) file.
Save UVs—Saves the UVW coordinates to a UVW
file.
Reset All—Restores the UVW coordinates to their
original status.
Reset All has almost the same effect as removing
and reapplying the modifier, except that a map
assignedintheEditUVWsdialogisnotdeleted.
For example, if you forgot to turn on the Generate
Mapping Coordinates check box for an object,
and then applied the Unwrap UVW modifier, the
modifierwouldhavenoUVWcoordinatestouse
and its settings would b e wrong. If you then go
back in the m odifier stack and turn on Generate
Mapping Coordinates, you’d need to choose the
Reset Al l command. When you do so, an aler t
warns you that you’re losing any edits you’ve made.
