I keep the majority of my operators on a hidden layer called Operators. However it’s a pain to turn on the layer when I need it on. In times past I’d either go to the layers, select operator, turn it on, or I’d go to an “all on” layer combination, or a special layer combination that was a “3D + operators,” or I’d select a slab, change it to the operator layer, then start drawing, click yes, turn on hidden layer… all of these are slow and annoying. The last one, though, led me to a great solution. Favorites. One of my saved favorites is a generic slab on the operator layer. So now to turn on the operators, I key command the slab tool (u), key command the favorites open (shift + ~), click on the operator favorite and start drawing. I have also added a separate 2D favorite on the operator layer as well (polyline) for when I need to turn on operators in sections/elevations/interior elevations. I could cut out one step if I left the favorites open, but I hate having the favorites open when I’m not using it; I find it distracting when it changes with each tool, which is the way I want it when it is open. This is one of those tricks that seem useless until you try it a few times.
