Pulled those below references from the Help Menu.
How I understand it is that we have nine standard crosshatch patterns,
included with Detailed Drawings in <loadpoint>/text/crosshatch. There is
no Wood crosshatch pattern included. But you can modify an existing one
and save it as Wood pattern in your crosshatch directory.
Pro/E searches for the specified file with .xch extension in the path
defined by the pro_crosshatch_dir configuration option, the working
directory, paths specified by the search_path configuration options, and
the default crosshatch directory.
If the specified file cannot be located, then the default cross hatch
pattern is used.
Hope it helps.
