Architecture, design, and media professionals all over the world are using Google SketchUp to create detailed 3D models efficiently and quickly. In Google SketchUp 6 Essential Training, design expert George Maestri teaches the foundations of SketchUp's drawing, design, and rendering tools. He covers the fundamentals of the application, the interface, and the Sandbox extension, which is used to create realistic organic shapes and terrain. George also discusses how to model and texture objects from existing photographs and export models to Google Earth to visualize how buildings fit in a real landscape. Exercise files accompany the course.
So we are picking this up from the last lesson and we did in that lesson was we matched the perspective of this photo to this perspective in SketchUp and now once we have done that, we can sketch over this photograph. We can basically use our Drawing tools. Now, the one thing about this is that we are really locked to a very specific view. If I were to orbit the scene, notice how it actually disappears because what Photo Match does is it actually has to lock to that specific view and we have that right here. All I have to do is just click on that scene and it will go ahead and reset itself.
So, I can use any of my Drawing tools to draw this building. So, let's go ahead and start with the Line tool and again I can't use Rotate, so I have to use just Pan and Zoom. I can orbit around. So, I am going to use my Line tool and I am going to draw the top edge of this building. So, all I have to do is just click and if you notice here it actually infers that there is a green axis and that actually matches my building. So, all I have to do is just draw this line here, match my blue axis here and then draw my building over and complete this and I have a rectangle.
Now, this is the side of my building. Now, if I looked at this in 3D -- I am going to orbit right now, you will see that I have actually created a rectangle that actually matches that building. So, I am literally building this in 3D, but I am using the photograph as my reference. So I click back onto my Scene tab and I have got it. In order to create the front of the building, I could either draw the phase or probably the easiest thing to do is to push pull. So I am just going to select my Push Pull tool and I am going to pull my face over to create the bank.
So, there we have rectangle that's basically the same size as bank. Now, there is some details in the front of this bank that we don't see. The other thing we can do with this is we can actually take this photo and we can project the pixels from the photo onto our object to create new textures. So, once I am in the Sketch Over mode all I have to do is go Project Textures From Photo and it's now projected that building onto that cube. So, if I orbit this you will see I actually have a cube that matches my photo.
So, this is kind of how you can do a very simple building for Google Earth or something like that. Now, we can do a little bit more detail here and let's go back to our view and let's for example do some of these windows. So, I can for example, zoom in here and just on this face I could actually just draw a rectangle to make this window for example, and just select that face and then just Push Pull that face in, so now I have a window that pretty much matches the window on the object. So, let's do that for this window as well.
So, you can see how it very easily creates a more realistic view of my building. So, I have got a little bit of an indentation here and again I could snap that do it and again just push that in using P for push. So, as you can see I can actually even go over here to these and I can model those as well. I can make those with a rectangle, and then of course we have an arch here at the top. So, all I have to do is just snap, snap and then make my arch about the same size to meet that edge, that take face and again push it in.
Now, once I start modeling like this you will see how I am actually creating some detail that may not be there. So, all I have to do is re-project the textures from the photo. And it gives me a little bit of an error and all it says is do you want to overwrite the existing material? So we say Yes and then it just goes ahead and it resets those. The last thing I want to model here is this little parapet that kind of comes out. Let's go ahead and try modeling that from the actual photo, but the one thing I find here is that when I try and draw out this angle, it's just trying to snap. So, probably the easiest thing for me to do is to do something else. I can actually just draw the top edge of this, which is actually going to be a line with a red axis and I can draw the bottom edge of this little parapet and so that gives me a face. And then I can just Push Pull that face out a little bit and I can just move that face up or down and if I hit the up arrow I can snag it to the axis and then again re- project those textures. Yes, I do want to overwrite.
So, now you can see I have got a building here that looks pretty good. It has got textures on the sides that I want them. I can certainly create new textures for the top or the other side, but now I have a building that's reasonably sized and pretty much like the one in my photograph.
