Well, let us say I have created a model with 50 views, and I would like to show at the end, all views e.g. on 51th view as an overview of the model structure. At this point of course, I will have all vars duplicated and lot of shadow variables on the 51th sketch.
How can I convert (is it possible?) shadow vars back to normal vars to show the relationships between those 50 views on the 51th view?
Select the "model variable" tool and click on the shadow variable, this will convert it to a normal variable and add all influences as shadow variables. Continue doing this to create the entire model.
