The 3D tree symbols on this page were created using AutoCAD R14 and so are compatible will all higher versions. All drawings are suitable for use as blocks within AutoCAD. The trees have been drawn at an appropriate size in metres. To insert a tree at the default size, simply use the default insert scale factor (1). Autocad blocks of trees, plants, group of trees, forests, branches, palms, oaks. The files are in dwg and dxf format. Drawings of trunks, branches, tree canopy, foliage, forest, garden.

There’s nothing like adding landscaping and people to a rendering to adda sense of life and scale. Computer images, in particular, need landscape props because they tend to appear cold and somewhat lifeless. AutoCAD offers a set of pre-built landscape objects to help soften the appearance of your rendering. Let’s see how you can add a few trees and people to the Facade model.
1. Choose View >Redraw, and then choose View >Render >: Landscape New
2. Click Quaking Aspen in the Library list, and then click Preview to view the item.
3. Use the slider just below the Preview button and change the Height value from 20 to 100, the highest setting.
4. Click the Position< button, and then click the point indicated in the top image of Figure 17.29 to place the tree in front of the buildings. You may have to adjust your view.
5. Click the View Aligned check box to deselect this option. This option is explained later in this section.
6. Click OK. The tree appears as a rectangle with a text label telling you what it is, as shown in the bottom image.
7. Copy the tree to the positions indicated in the bottom image.
8. Now render the view. You will see a view similar to Figure 17.30.
The trees you added are actually two-dimensional bitmap images. If you view the model from a glancing angle, the trees will begin to look thinner and you will see that they are indeed two-dimensional. Two of the options in the Landscape New dialog box offer some options to reduce the 20 effect. The View Aligned option you turned off in step 5 forces the tree to be aligned to your point of view, so you never see the object edge-on. Another option, Crossing Faces, creates two images of the object to appear. Each image is crossed over the other,creating an almost 30 look.
1. Redraw the screen, and th -n click one of the trees to expose its grips.
2. Click the grip at the base of the tree, right-click the mouse, and select Rotate from the popup menu.
3. Type 180.J to rotate the tree 180 degrees.
4. Click the grip again, right-click the mouse, and this time select Scale.
5. Enter 2.4.J to increase the size of the tree by 2.4 times.
6. Repeat steps 1-5 for each of the other trees
7. Open the Landscape New dialog box again and select People #1 from the list.
8. Enter a Height value of 66, and then use the Position button to place the people at the entrance of the Facade building.The people will appear as triangles in the Wireframe view, (Make sure you use the Nearest Osnap override to place the People.)
9. Click OK. Then repeat steps 7 and 8 to place People #2 in front of the office building between the trees.
10. Render the view. Your view will look similar
The shadows of the trees now match the sun’s loca ) und they are a size better suited to the model. However, notice that the people are not lit very well This is because when you placed them, you did not turn off the View Align option. Therefore, they are facing your view tilted slightly away from the sun. This has the effectof darkening their image.
You can use View >Render Landscape Edit to change the settings for landscape objects. You will be prompted to select an object. Once you do, the Landscape Edit dialog box appears, which is identical to the Landscape New dialog box. From there, you can make changes to the settings for the selected Landscape object.
Other Rendering Output Option
Autocad Insert Field
Throughout this chapter, you have been rendering to the AutoCAD drawing area. You can also render to a file, which enables yod to recall the image any time in. any application, or render to the Render window. From there, you l.ave a number of options in dealing with the rendered image.
Rendering to the Render Window
The Render window lets you control the resolution and color depth of your image. It also lets you save the images that you render in the Wmdows .bmp format Another advantage of the Render window is that you can render several views and then compare them before you decide which ones to save.
1. Open the Render dialog box. and then select Render Window from the Destination drop-down list near the bottom of the dialog box.
2. Click Render. After a moment the Render window appears. It then takes a minute or two before the image finishes rendering and appears in the window. Notice that the image is within its own window. If you render another view, that view will also appear in its own window, leaving the previous renderings undisturbed. You can use File >Save in the Render window to save the file as a .bmp file for later editing or printirig, or you can print directly from the Render window. You can also use the Render window to cut and paste ‘the image to another application or to view other files ill the bmp format.
To set the size of renderings, you use the File> Option tool in the Render window. This option opens the Wmdows Render Options dialog box. Here, you can choose from two standard sizes or enter a custom size for your rendering. You can also choose between 8-bit (256 colors) and 24-bit (16 million colors) color depth. Changes to these settings don’t take effect until you render another view.
Rendering Directly to a File
Rendering to the Render window allows you to view and compare your views before you save them. However, you can only save your views in the .bmp format, If you plan to further edit the image in an image-processing program, this may not be a problem. But if you want to use your image file with a program that requires a specific file format, you may want to render directly to a file. Here’s how it’s done.
1 Open the Render dialog box, and then select File in the Destination button group in the lower middle of the dialog box.
2. Choose More Options at the bottom of the Destination button group. The File Output Configuration dialog box appears.
3. Click the File Type drop-down list to see the options. You can save yOU’image in .gift. .pcx, or even PostScript format. There are also several other formats available. You might also notice the other options available ia.the dialog box, such as color depth, resolution, and compression. Not all these options are available for all the file types. For example, .gif is limited to 2S6colors, so the other color opti~ns will not apply to .gif files.
4. Click OK to return to the Render dialog box, and then click the Render button. The Rendering File dialog box appears, prompting you for a filename lor your image.
5. Enter Facade 1. AutoCAD adds the filename extension for you.
6. Click OK and AutoCAD proceeds to render to the file.
As AutoCAD renders to the file, it tells you how much of the image has been rendered in the command line.
