Clean up and visualize the entire bicycle

“

- [Instructor] Now that the last object has been completed let's visualize the entire bicycle. Let's turn on all the layers, type layon, zoom out. As soon as you start orbiting, the bike will pop down into its orientation on the ground which was useful when we were modeling the bike. But now I'd like to tilt up the bicycle so it looks more like a real bicycle and it will just give a more natural behavior to the orbiting command. Of course we can get around that using 3D Free Orbit as we have several times before. But when we leave this project I'd like to finalize it by rotating the bike up. I'd also like to turn off all the 2D layers that we used in generating this 3D geometry. So I'll come over to the Layer Manager and let's go to the 2D Layers property group, right click, and say Visibility, Off. One thing I notice is that the tank disappears, we're going to Undo, and let's see that's on layer Tank. So the most expedient way to fix this, would be just to rename this layer, and put a dash in front of it. To indicate that it is now a 3D layer. Now I can turn off the 2D layers again and the tank remains. Also, I'm going to change to Shaded mode and I can see that there's some profiles here that are on the wrong layers. These are on 3D layers and you could correct each one of those if you want, but I'm just going to go ahead and delete these profiles which aren't really needed anymore and then I notice also over here that we have some paths in here that we can get rid of. Which are also two dimensional objects and now I'd like to rotate the bike up and I need to change the UCS so I can rotate it around the Z axis, so I'll type UCS Enter, Y Enter, Enter and then RO for rotate and I'll rotate everything here Enter, and I'm going to rotate it around the origin point, zero, zero, Enter and then AutoCAD's going to take a moment to think about this because it's a lot of information. I need to turn on Ortho, I'll press F8, to toggle Ortho mode on and then I'll click over here in this case to specify that 90 degree angle and in a moment it will complete the operation and the bicycle is now tilted up. Let's also orbit around here and orbiting is much more natural now, the bicycle is in the upright position. We don't really need to use 3D Free Orbit any longer. Also I'd like to get a perspective view of the bicycle, so I'm going to come over here to the View Cube and click on this arrow and change to Perspective and then I can orbit into some pleasing composition here, like this, also I notice that the back wheel looks a little bit jagged, I can change that in Options right here with Rendered object smoothness this effects rendering as well as shaded views, such as the one we're looking at. So I'm going to change this to a higher value, let's say three, and that should smooth out some of those jagged edges. Also I'll reset the UCS, and let's turn on shadows. I'll type the word shadow, and you can see that we have a couple of choices here, I'll use visual style for shadows and that's a system variable that can either be off, or on. I'll type 1 + Enter to turn it on. So now we have a representation of the shadow, it just makes it look a little bit better. So congratulations you've really come a long way in this project you have learned a lot about advanced modeling techniques using surfaces, solids, and mesh objects. So again congratulations and thanks very much for taking this course, I hope you enjoyed it, and learned a lot.
