I am working on a support frame in a small model and for whatever reason, when I try to make a material list the system begins creating a model extract but cannot complete the process and I usually end up forcing the program to close and then restarting.  I have tried a few different methods of generating the list but none seem to work.  I even tried saving the model with a different name and removing other parts of the job that aren't connected with this frame and I'm still having this problem.  The program was working great last week but today, no way!! Please let me know if I need to check a setting or try something different
