Chances are you have already discovered rollover tooltips. It doesn't take long before you notice that if you hover over an entity, AutoCAD displays a pop up window that tells you a little bit about the object. Let's take a look at how the rollover tooltip function works. I am going to zoom in on my geometry a little bit and let's take a look at a rollover tooltip. If I place my cursor over this geometry and wait just a second AutoCAD brings up a pop up that tells me a little bit about that object. I can see it's an arc and I can see some of its general properties. Let's place my cursor over this object. Once again AutoCAD is giving me some more information. Now if you are not seeing the tooltips on your screen, this feature is turned off on your system. Let me show you where we can go to turn this on.
We are going to visit our Options dialog box. To get there I'm going to right-click and select Options from the menu, and we are going to go to the Display tab. And right here in the Window elements area, if I come all the way down to the bottom, I could see a toggle that allows me to turn my rollover tooltips on and off. I'm going to leave mine on, and we'll come down and click OK. Let's back up a little bit and I'm going to pan this drawing down. Using the rollover tooltips is a lot like interrogating your drawing. For instance what layer is this guy at? He's on layer det -2, what layer is this guy at? Det-6.
What's this object? Is it a block or is it polyline? I can see it's a block. Now some people have a love-hate relationship with the tooltips. They don't like the idea of these guys popping up whenever they hover too long. If you happen to be one of these people, by all means turn it off. Let me show you one small problem with the tooltips and it involves multiline text. Watch this. If I place my cursor over this text AutoCAD doesn't give me a tooltip. This text was created using the multiline text editor. Oddly enough if we want our tooltip we have to place our cursor just above or below the text to get the tooltip to come up on screen. So it's not the end of the world.
Just something to keep in mind if you want your tooltips to work in most situations. The beauty of the roll over tooltip is that we can get information without having to select our geometry. Because of this, rollover tooltips can be the fastest way to review your drawings.
