Sometimes when selecting objects, we may select more than what we intended. In this lesson we're going to learn how to remove objects from a selection. Take a look at the geometry on my screen. We're going to look at these shapes on the left first. Let's say I'd like to erase all of these green circles. To do that, I'll launch the Erase command, and then I'll click right here and I'll create a window selection around this geometry. Now, I've obviously selected too much, let me show you how we can deselect entities. If I hold down my Shift key, I can click to select each of these rectangles, and they will all be removed from my current selection.
I can now remove my finger from the Shift key, and since I'm finished selecting objects, I'll right-click to finish the command. I'm going to move up and click Undo to bring this geometry back, and let's make another selection, this time we'll turn it up a notch. Let's say I'd like to erase all of the green circles in this drawing. To do that, I'll launch my Erase command. I'll click right here and I'll create a window selection around everything. Then I'll hold my Shift key, and instead of clicking these rectangles one at a time, I'm going to click in the middle of this rectangle, and notice that we can use a selection window to deselect entities.
I'm going to click right here to finish my crossing window to deselect those rectangles. I am continuing to hold Shift. I'll come over here and click. I'll make a crossing selection across this geometry. When I'm finished, I'll right- click to complete the command. I'm going to click Undo to restore the geometry, and I'd like to try one more, this time I'd like to move these rectangles. Let's see how fast we can select them. I'll launch the Move command, and then I'll click right here and create a window selection around these entities, and then I'll hold my Shift key and create a crossing selection to deselect these entities.
When I'm finished, I'll right-click, and I'd like to move these rectangles from the end point right here. I'll come down and lock my Ortho, and I'd like to move these guys' ten units to the left. So, removing entities from a selection is as simple as holding down the Shift key. Let's pan this drawing over. I'm going to zoom out a little bit. Let's see if we can use this Removal feature to help us make a design change to this geometry. On my screen, I've got a drawing of a large cabinet. This top portion has a pair of glass doors.
Behind the doors are some shelves. Now, I like the doors, but I'd like to create a variation on this cabinet design where the doors are removed, and I'm wondering what that would look like. So, I'm going to have to erase some of this geometry. Let's zoom in a little bit. I'll launch the Erase command and I'm going to click right here and create a crossing window that crosses over all of these entities. I'll click to finish the window, and I've selected too much. I'm going to hold my Shift key and I'll make a crossing selection across my shelves, because I'd like to keep those entities.
I'll continue to hold Shift and I'll click this right edge and the left edge, because I'd like to keep that geometry as well. Now that I'm finished, I'll right-click to compete the command, and we'll clean this geometry up using the Extend command. I'll move up here and launch Extend and I'll select the left and right edge as my boundary edges, and I'll right- click, and then I'll create a crossing selecting across the endpoints of these lines to extend them to the left. I'll create another crossing window across these endpoints to extend them to the right.
When I'm finished, I'll hit my Esc key. So, the next time you're selecting objects, and you select more than what you need, whether it be intentional or unintentional, you can always remove entities from your selection by using the Shift key.
