AutoCAD 2007/2008/2009 DWG Format

[#1]

I want to use my hatch patterns I had created/addled to on a previous version of AutoCAD (2002). Where do I locate the hatch pattern file (acad.pat). I looked every where but 2008 keeps showing the standard patterns

That'll depend on how you added them onto AutoCAD 2002.
If you added them in the acad.pat file then you'll have to look for this
file from that previous version of AutoCAD and replace the one AutoCAD 2009
is using.
If you added them in separate files with extension type of .pat, then you'll
need to copy all those .pat files into one of the folders in AutoCAD's
search path.

To locate where any version of AutoCAD finds acad.pat, at the command prompt
type:

(findfile"acad.pat")

Thanks I did find the file, however I had made changes to it, but when using hatch, AutoCAD still shows the standard hatch palette not the new I want to use. AutoCAD still must be using another file located somewhere else other than the support directory.

Where does AutoCAD store this file.

What I would try next is to edit the acad.pat file, copy & paste one of the
custom hatch patterns into a new text file with the matching file name.

For example, if the custom hatch pattern has a name called 3BRICK, the text
file name should be 3BRICK.pat.

Save 3BRICK.pat in a folder that is on AutoCAD's search path as listed under
Options>Files tab>Support File Search Path

Now execute the HATCH command and click on the ... button or double click on
the Swatch pattern.
Click on Custom tab and you should see 3BRICK.pat listed here.

I don't recommend modifying acad.pat due to potential data loss on an AutoCAD upgrade.

Copy individual custom pat files to:
%APPDATA%\Autodesk\AutoCAD ????\R??\language\Support
They will automatically display on the custom tab of the hatch dialog.

You mentioned hatch "palette". If you're using a palette instead of the hatch dialog, you're probably best off to create your own custom hatch palette.

Obvious way is to keep a copy of the added data in a separate file to be
able to add back in to the next version. Mine is 3519K. It does take a bit
of time to use an added customized pattern though so they aren't used much
from the picture selection method.
