I have been fooling with pulling hatch patterns from old .pat files, and in the course of trying to extract one of my favorite hatch patterns (wood endgrain), I seem to have somehow corrupted my installation of AutoCAD with respect to the .pat file it reads from. Part of my problem is that in AutoCAD 2006, I don't know how to tell what specific acad.pat file is being used by AutoCAD.
My problem now is that any time I issue the Hatch command, I get an error that says:
"Error in reading the pattern file"
then the hatch pattern palette windows are all blank except the "Other Predefined," which contains only the one endgrain pattern, which is apparently the offending pattern. No matter what I try now, I can't seem to reset the patterns back to the acad.pat which I can find in what I suppose is the correct directory, which is a directory I have set in my support file search paths.
No matter how many times I try reopening and creating a drawing from scratch, this problem will not seem to go away.
Thank you very much in advance for any help. . .
