The 2005 and later releases still provide those additional hatches (161 of them in 2005-2007; there were 236 in the final beta of 2008), but instead of including them in the main acad.pat/acadiso.pat file and leaving it to the individual user to edit that file, the additional hatches are provided as individual custom hatch pattern files [custom PAT files can only contain one pattern each]. This makes it as easy to control the patterns you have available as moving a file between folders in Windows® Explorer. But you do have to be aware of two things:
- The folder[s] in which your custom hatch patterns are kept must be on the AutoCAD search path in order to be available inside ACA/ADT. If you have a standalone installation, using the default folders, the out-of-the-box custom hatch files can be found here:
C:\Documents and Settings\[yourusername]\Application Data\Autodesk\[ADT version folder]\enu\Support\pats
where, of course, you would substitute your user name and the folder name for your version of ACA/ADT in the corresponding locations in red. - The custom hatches are found on a separate tab, labeled "Custom" [imagine that!], in the Hatch Pattern Palette dialog.

If you needed additional architectural hatches and were unaware that these were available, now you know they are available and how to access them. If you can not find a pattern that meets your needs in the ones that ship with ACA/ADT, you could always make your own custom hatches or search the Internet for additional hatches created by others. The Help has a very good section on how to create custom hatch patterns for those interested in learning.
