In previous releases osnaps would honor hatches, in 2005 they are ignored by default. There has been a change in behavior in AutoCAD 2005 regarding the object snaps on its geometry. Any hatch pattern you find should work with any previous or future version of AutoCAD! The good news is that the hatch pattern format hasn't changed since it was first introduced years ago. Watson has donated these hatch patterns to the AutoCAD community.
You may place these patterns on your system and use them in your drawings.To download these free AutoCAD hatch patterns, simply right click on the patterns you want and choose Save Link As, then place the PAT file in a path included in your AutoCAD support paths.
