Hi Maxim

I am having a similar problem adding hatch patterns.  I tried the method listed above, by adding the folder with the hatch patterns from preferences.  But I think my hatch pattern file has many hatch patterns within the .pat file.  How do I add these and not have the autocad Lt crash?  I did it with no problem on my old windows laptop but now using a new macbook pro with Autocad Lt 2014.  Also my desktop version is Autocad Lt 2013 and I am having the same issue.  

I have attached the two hatch pattern files i am trying to add as well as a picture of what is currently in my support folder (new hatches not there because they cause Autocad to run very slow, even just open)

Thank you!
