Can you lock objects in Illustrator so it doesn't keep being selected and highlighted?
I was trying to draw behind many shapes but I couldn't tell where I was drawing because of many lines highlighting. But I need those shapes to draw correctly just not their stroke lines highlighting. Usually a problem when adjusting curved or making anchor point using pen tool.
How do I lock objects in Illustrator to keep this from happening?
Yes, in the layers panel, there is a little checkbox next to every object and layer.
Layers Panel icons as KMSTR points out.
But there's also....
Object > Lock > Selection (Command/CTRL+2)
Object > Lock > All Artwork Above
Object > Lock > Other Layers
And there's a hidden shortcut Command/CTRL+Option/Alt+Shift+2 to "lock others". This command will lock anything NOT selected.
