I seem to have hit a hotkey combo by accident or changed some preferences in Illustrator and I can't figure out what.
When using the selection tool (V) and hovering over an object (Object selection by path only is disabled), the blue outline would normally show all objects which are grouped with the object I was hovering over. This "preview" is very useful for me to be able to see groups.
Now, when I hover over an object with the selection tool, all that I can see is the outline for that one object. To see if it is grouped with other objects and what those objects are, I have to now actually click to select the object and then the entire grouped set is selected as expected. This behaviour was not the norm as of yesterday. This seems trivial but when I have literally hundreds of groups in a file, it is extremely tedious to go through and click on each one to see the current group rather than quickly hover. Does anyone know how to fix this?
I had the same issue and found this page, but nothing here seemed to solve it.
I did some hunting and found that I had somehow pressed the shortcut for
Hide Edges - or cmd + H.
You can toggle this by going to
View > Hide Edges.
I must have accidentally hit H instead of G. Hope this helps.
