I'm using AutoCAD LT 2013 for Mac.
I have searched other threads about loading new hatch patterns but haven't found an answer to my dilemma. Most seem to deal with locating the correct folder to place them in. I have done this correctly(or so I assume). The hatch patterns I downloaded (.pat files) are now in the same support folder that contains acadlt.pat and the like. The new patterns show up in the library list but do not have a preview image in the box next to the name like all the standard ones do. Rather the box is white with a red diagonal line through it. When I try to select the pattern it says "error in pattern file." I tried this with .pat files from other sources to doublecheck the patterns I'm trying to use aren't corrupted with the same result. Just fyi: the patterns are from eldorado stone. If anyone has any ideas please let me know.
Thank you!
Mark
