Hi Stefano,

No, the Types > Edges control will target all edges for hiding/showing or all visible edges for selecting. There isn't any way to make one specific edge exempt from its handling.

But you can assign the edge to its own style or name to control it using the scene browser. Or maybe assigning all the other edges of the object to their own name or style would be good so then you could show them without affecting that one.

There are also some controls for how edges are displayed in Options > View. You can make them be a little lighter or darker than the regular style color there. That's a global setting though.

Not exactly because the states in the scene browser are not global settings, they're just a reflection of the combined state of all the individual objects that are addressed by that scene browser item. The hide/show property is on individual objects, using the scene browser lets you do an action like hide/show/lock/select on a set of objects but the scene browser item does not itself own the property.

So when you go to Styles > Red and do a hide there (click on the eye), that hides all the objects that have a style assignment of Red. It doesn't change a property on the style itself.

This system is why it is possible to have different categories of controls (object names, types, styles) that can be used in combination with each other, because they're all manipulating individual object properties. If they were global states (like layers often are in other programs), then it becomes difficult to do something like hide the Red layer and then go show just one named object that also happens to be on the Red layer.
