Anyone else open a MX4 files and find that you machine group is missing from the file. Toolpath Group is there, but the machine group not. So I add a machine group and move the operations into the newly created machine group now when I open one the operations, none of the tools used are listed. Now I closed off Mastercam, re-opened it and the file and the tools are there. MASTERCAM SUCKS ASS!!!!
