In SketchUp 7 New Features, George Maestri reviews the major enhancements to Trimble's free and user-friendly 3D modeling software. One of the most exciting changes is the addition of Dynamic Components, and George takes an in-depth tour of their features, including built-in animation and the ability to scale without distortion. He also reviews the new point-and-click Interact tool, which allows users to customize Dynamic Components without the use of a keyboard or menus, and the improved Line tool, which transforms intersecting lines into separate segments. Other improvements include updates to the 3D warehouse and the ability to download models directly from Google Earth. Exercise files accompany this course.
One of the most important new features in SketchUp 7 is the way that the Line tool works. Formally, when you've drawn lines that intersect each other, what happens is those lines simply overlap. With SketchUp 7, what happens is the lines actually do intersect and create multiple lines. Let me show you how this works. I'm actually going to start this in SketchUp 6. So, I have that on my screen and I'm simply going to draw a simple plane. Then I'm going to select my Line tool and just bisect that plane.
Now if I select this line by itself and just use the Move tool, you can see that, well, we've already kind of cut this in half. If I get this going up and down the blue axis, you can see how you can make like a peaked roof or something like that. Now if I undo this and I draw another line, in SketchUp 6 what happens is this line is actually just on top of this as well. We don't have an intersection point here. So, for example, if I selected this line and did the same thing and I just moved that up along the blue axis, you can see how the original line doesn't move at all.
So, I get kind of a weird behavior. Now this actually changes a lot in SketchUp 7. So let's go ahead and do the same thing in SketchUp 7. I'm going to go ahead and delete this guy and let's go ahead and just do the same thing. We're going to draw a plane and I'm going to use the Line tool to bisect that. Again, we have the same behavior, so when I move straight up that blue axis, you've got a peaked roof kind of thing. Now, let's go ahead and just draw that second line.
You'll notice it changes immediately, because what happens is you can see here we've got some additional little ticks here. These become separate lines. So, if I go back to SketchUp 6, you can see how the lines formally don't intersect, but when we go back to SketchUp 7, you can see how it bisects these lines. Now this is much more intuitive and I really think this will make drawing much easier in SketchUp 7. So, that's the big change with the Line tool.
