I did this once but I don't remember how I did it. When right click on the assemby/part in the Feature Manager Tree, I want to customize what shows up in fly out menu. eg, to show "Open Drawing" I have to expand the menu. At one time I customized this and when I right click on the top level item in the tree the "open drawing' used to be in the menu. Can someone please jog my memory how I did this?
