I am using AutoCAD Mechanical 2007. Currently we are in the process of switching to using named plot styles and we have been able to convert my .CTB files using CONVERTCTB and my files using CONVERTPSTYLE but once we open up the Plot Style Table Editor both the "Add Style" and "Delete Style" buttons are grayed out. How can we fix this?
