I have a drawing with several surface lofts. I need to add some connectors to control the way the lofts are generated. With some of the lofts I can right-click on one of the profiles and select Add Connector from the menu and everything is fine. But with some other lofts I right-click on one of the profiles and the menu shows me Show All Connectors, Hide All Connectors, and Reset Connectors. But there is no Add Connector in the menu. I cannot figure out how to add connectors to these lofts. Some lofts behave properly, and some lofts will not let me add any new connectors. I am at the end of my rope, and cannot figure out what might be wrong. Anyone have any ideas?
