Due to a needed shift in my company's direction it has become necessary for us to shift away from PostBuilder to a 3rd party posting solution (in our case ICAM). Our training on this is scheduled for next week but I am looking into some the foreseeable issues. One of the things we have done for a long time is to use the Tool Attributes to define additional needed information that is not handled by the cutter definition. Our Siemens controls can use an alpha-numeric for a tool number and to control this we use a Tool Attribute Variable to pass the information to PostBuilder since NX is incapable of utilizing this feature of Siemens controls. Is there a way to customize the CL File Output to read these variables or will we need to convert to using UDE's. I looked at the documentation but I am not finding a lot of information, of course I could just be looking in the wrong place. Any help would be appreciated.
