In one of my drawings I can't edit some hatches without the following warning coming up:
ERROR IN READING THE PATTERN FILE
In the hatch menu only certain hatches are listed but in other drawings the full range of hatch types are listed in the menu and I can edit all of them
The hatches that are causing me trouble in the problem drawing are GRAVEL and AGGREGAT.
Can anyone help me here? Is there a way I can get the hatch attributes in another drawing to be imported into the problem drawing?

It sounds like you have two pat files and one is corrupt (? strange).
One workaround in any one drawing would be to temporarily change all the affected hatch objects to a different pattern and purge out the bad hatch definition. Copy and paste an area of hatching from a "good" file into the affected one and use match properties to apply that hatch to the original objects. Probably.
By default, there are 2 hatch patttern files, ACAD.PAT and ACADISO.PAT.
If the drawing's MEASUREMENT variable is set to 0, AutoCAD read the ACAD.PAT hatch pattern file. If the drawing's MEASUREMENT variable is set to 1, AutoCAD reads the ACADISO.PAT hatch pattern file. It sounds like one of these does not have the hatch definitions you mentioned.
A simple test is to check your MEASUREMENT variable value and change it (from 1 to 0 or 0 to 1). My guess it is set to 1 (metric, ACADISO.PAT) and the gravel hatch is in the 0 setting (imperial, ACAD.PAT).
Doh! That's probably right.Quote:

If it's in the standard PAT files this is not recommended for 3 reasons:
There's basically 2 ways a standard hatch like GRAVEL can become corrupt:
- If there's an error with the definition, any hatches defined after the custom hatch won't load.
- If there's an error, loading the file (i.e. open the Hatch dialog) will become very slow.
- If AutoDesk gives an update these files may be overwritten ... losing any custom hatches.
Find your installation CDs / DVD and copy these files from there ... it should solve the problem for GRAVEL at least. For AGREGAT, you need to find the orriginal version of the AGREGAT.PAT file (maybe through Google).
- Someone's changed the standard PAT file(s) and inadvertently made a mistake.
- The hard drive had a problem sometime and the file itself became corrupt.
