The more geometry you have in your drawing, the more things tend to get in the way when you work. To help make our lives easier, AutoCAD 2011 gives us a new Isolation tool that lets us focus on specific entities, no matter how busy our drawing may get. On my screen I have an architectural example. This is an elevation view of a single-family home. This drawing has a fair amount of line work. Let's see if we can make some changes, while also simplifying what we see on screen. I am going to start out by zooming in on the front door. And since my changes involve this geometry, I would like to isolate it in my view.
To do that, I am going to come down to the new Isolate Objects icon and click. And I'll select Isolate Objects from the menu. And we will then click right here and make a window selection around this geometry and right-click. And notice AutoCAD has isolated that geometry on my screen. It's not doing this by turning off layers. Notice if I open up the layer control, all of my layers are still turned on. AutoCAD is physically hiding all of the other geometry in this file. Well, now that my drawing is simplified, let's make some changes.
I am going to zoom in and we'll correct our door hardware. I am going to launch the Trim command. I'll make a crossing window and select these lines, right-click, and I'll remove this extra line. When I am finished I'll hit my Escape key. Let's back up and I'd like to make another change. I would like to reduce the height of these windows. I'd like to change them from four panes down to three. But before I do that I would like to hide this door handle hardware, such that it doesn't get in my way.
Once again I'll come down to my Isolate Object tool. Notice it's now red. Whenever you see the red light bulb, you know that there is geometry being hidden in the current file. I'll click the icon. And this time instead of isolating objects I would like to hide some objects. So I'll select Hide and I'll make a window selection around this hardware and right-click. And that geometry has been added to the other hidden geometry in this drawing. To modify my windows, I am going to use the Stretch command. I will then make a crossing window around the bottoms and I'll right-click.
And I would like to stretch them from the endpoint right here to the endpoint there. And finally we will practice good form. I do have some extra line work here. Let's launch the Erase command and I'll click one time on each of these entities to remove the extra line. When I am finished, I'll right-click. Let's back up a little bit and now that I am done making my changes I am going to come back down to my Isolate Objects tool and we will select End Object Isolation. And AutoCAD will restore all of the hidden geometry to my screen.
Now if you like using this command try accessing it from the right-click menu. Notice if I right-click I can come down to Isolate and all of my isolation options are right here. Remember that Object Isolation will isolate geometry independently of the layer settings. Using this tool is a great way to simplify your geometry, such that you only see the entities necessary to accomplish your task.
