3 Summary This guide is intended to give a basic guideline to follow in order to create an average 3D model using Google SketchUp (hereafter call SketchUp) as the modeling tool and DS Sketch3D. The following basic steps will be explained: Step 1. Download the plugins, components and material textures you need from the DS Sketch3D Download Site Step 2. Bring your CAD drawing into SketchUp Step 3. Clean up the CAD drawing Step 4. Model the house (or building) and roof Step 5. Model the terrain Step 6. Apply material textures Step 7. Replacing 2D Symbols with 3D Models Step 8. Create Scenes Step 9. Render your Model for Presentation Basic SketchUp Tools You Need to Know In order to follow the process explained in this guide you need to become familiar with the following tools: Icon Name Description Pan tool Orbit tool Select tool Eraser Move tool Push/Pull Navigation tool for panning around the model Navigation tool to rotate your view Tool for selecting objects in the model Tool for removing objects in the model Tool for moving or copying objects Tool for pushing or pulling faces 3

4 Step 1: Download your Plugins, Components and Material Textures Before creating 3D models in Google SketchUp make sure you have the proper tools, 3D libraries and textures. You can download these from the DS Sketch3D Download Website: Plugins: If you are using a CAD drawing (DynaSCAPE or AutoCAD) as the base for your 3D model, you will save yourself a considerable amount of time if you download the CAD Cleanup Scripts plugin from the Plugins page. For help in downloading and installing plugins go the FAQ page of the DS Sketch3D website. Components: Your best source for landscape components is the DS Sketch3D Download Website, where you will find 100 s of models of plants, rocks, ponds, pools etc. Download the models you need. For help in downloading and installing components go the FAQ page of the DS Sketch3D website. Material Textures The DS Sketch3D Download Website has a number of landscape-specific material texture libraries that you can download and use in your SketchUp model.. For help in downloading and installing material textures go the FAQ page of the DS Sketch3D website. Step 2: Bring your CAD Drawing into SketchUp Choose your Starting Point From DynaSCAPE: If you are using the latest version of DS Design (5.5 or later) you can export directly to SketchUp format. The file created can be opened with SketchUp without any special import function. From AutoCAD or other: If you are using AutoCAD or another CAD program that can convert to a.dwg, you can import your CAD drawing into SketchUp. However, importing.dwg files is only available with the Pro version of SketchUp. From scratch: You can also begin your drawing from scratch right in SketchUp. You won t need to perform any cleanup so skip to the 3 rd step: Model the House (or Building) and Roof 4

Step 3: Clean Up the Imported CAD Drawing If your drawing was converted to SketchUp from DS Design or imported as an AutoCAD file, you will need to do some cleanup before you can begin modeling.

5 Step 3: Clean Up the Imported CAD Drawing If your drawing was converted to SketchUp from DS Design or imported as an AutoCAD file, you will need to do some cleanup before you can begin modeling. All files that are converted or imported from CAD are changed in a way that prevents SketchUp from creating faces with the CAD geometry. Faces are needed in order to create a 3D object and to apply a material texture to. Follow these steps to clean up the drawing: 1. Imported AutoCAD drawing usually come in as a group which will need to be exploded. The DynaSCAPE CAD Cleanup plugin will not touch geometry inside groups or components. 2. Begin by running the DynaSCAPE CAD Cleanup plugin you downloaded from the DS Sketch3D Download Website. It will be located in Google SketchUp under the Plugins menu. Select DynaSCAPE Tools and then Run CAD Cleanup (All). Don t have this plugin? If you have not downloaded this plugin, go to click on the Plugins menu in the left side panel and choose the CAD Cleanup Scripts plugin to download. Can t see the Plugins menu? If you can t see the plugins menu you will need to activate it. Go the DS Sketch3D FAQ page and browse to the section called How to enable the Plugins menu. 3. The cleanup script will run automatically, scanning the drawing and repairing any problems that may exist and then turn every closed area that it can into faces. For large drawings this may take a few minutes and it may appear that SketchUp is not responding be patient! When the cleanup is complete a dialogue box will appear showing the results. Click OK to continue. 5

4. Check your drawing to see if there still are any faces that were not created.

where gaps where too large for the script to fix.

6 4. Check your drawing to see if there still are any faces that were not created. Try running the Cleanup script again or you may need to manually close open areas by adding lines where gaps where too large for the script to fix. Faces are identified by the dot hatch that appears when you select them. Before Cleanup After Cleanup Tip: When using the DS Design export to SketchUp format, the default style has a purple Back color and a yellow Selected color. To change this go to the Window menu, select Styles and pick one of the default styles. The style called Default Style is a good one to use. 6

Step 4: Model the House (or Building) and Roof Modeling the house should be and fast and efficient since it is not what you are trying to sell with your landscape model.

7 Step 4: Model the House (or Building) and Roof Modeling the house should be and fast and efficient since it is not what you are trying to sell with your landscape model. Using the proper techniques and tools you should be able to do this quickly. Download the Roof Tool: Before you start, make sure you have the roof making tool in your plugins list. If you don t, go to the Ruby Depot website and download the roof plugin called Roof-v2-1. Follow these steps to build a simple roof: 1. Apply a material texture to the house face that best represents the exterior walls of your house. By applying a texture to house surface first SketchUp will automatically apply the texture to all the walls when you pull it into a 3D shape. 7

8 2. Next, use the Push/Pull tool to pull the house surface up into a 3D shape. Watch the Value Control Box at the bottom right corner of the screen to help you pull to the desired height or just enter the value on your keyboard manually and hit [Enter]. 8

Highlight the roof with the Select tool and then go to the Plugins menu and select Roof There are a number

9 3. Before using the Roof tool, erase all extra lines in the house wall that are not needed. The roof tool may not work if you leave them. 4. Highlight the roof with the Select tool and then go to the Plugins menu and select Roof There are a number of roof styles to choose from. The first style, Hipped Roof, is a common style to use. For more information click on the Help option on the roof menu to open the Roof Help page. 9

10 5. When selected, a modifier will appear allowing you to set some parameters. The defaults will work for many roofs. 6. Click OK. The roof will be created for you. Refer to Roof Help if you are having problems. 10

All the DS Sketch3D doors and windows are set to automatically glue to any surface and cut the opening in the wall, making it easy to place and move them.

11 7. The created roof comes in as a group. To apply a texture, double-click on the roof to open the group for editing. Once opened you can apply a roof shingle texture to the roof surfaces to complete the roof. 8. Next find the door and window components. All the DS Sketch3D doors and windows are set to automatically glue to any surface and cut the opening in the wall, making it easy to place and move them. If you downloaded them from the DS Sketch3D Download Website, they should be in your components folder. Go to your Window menu and select Components to open the Components Browser. 9. Click on the Navigation button and choose Component (see image below). 11

If your house has a front porch, place the front door in the approximate location.

12 Your door and window components should be found here if you followed the instruction on the DS Sketch3D FAQ page. Choose the components that you need and place them on the house. If your house has a front porch, place the front door in the approximate location. Once the porch is created the door can easily be adjusted. The DS Sketch3D doors consist of 2 separate components: a frame and door. There are a number of frame and door styles and combinations to choose from. 12

To create a porch and step(s) follow these steps: 1. Apply textures to the porch and step(s) first. 2.

13 Step 5: Model the Terrain Modeling the terrain is generally a more advance process but, as outlined in Step 5, simple grade changes like steps and front porches can easily be accomplished with the Push/Pull tool. To create a porch and step(s) follow these steps: 1. Apply textures to the porch and step(s) first. 2. Then, using the Push/Pull tool, pull the porch and step(s) up to the appropriate height. 3. Adjust the door height as needed. 13

If you have created shapes for your hedges, apply one of the DS Sketch3D hedge textures.

14 Step 6: Apply Textures Once the terrain has been modeled it is time to apply textures to the rest of the surfaces in the model. If you have created shapes for your hedges, apply one of the DS Sketch3D hedge textures. Apply hedge textures (with trunks) first and then pull the hedge(s) to the desired height. To finish, apply the matching hedge texture (without trunks) to the top of the hedge(s). 14

15 Step 7: Replace 2D Symbols with 3D Models If you are developing your model from a CAD drawing that has symbols (DynaSCAPE library figures or AutoCAD blocks ), this step is the most fun and can transform your model quickly. If you do not have these symbols on your drawing you will have to insert the 3D plant components manually. If you grouped your figures in your CAD program you will have to insert the 3D plant components manually as well. Keep this in mind when preparing your CAD drawing. To replace your 2D symbols with 3D models follow these steps: 1. Zoom in to your model to a plant symbol and, using your Select tool, left-click on it to highlight it and then right-click. 2. In the menu that appears choose Reload. 15

$instructions in the DS Sketch3D website FAQ page, this should be C:\Program Files$ $[(x86)]\google\google SketchUp 8\Components).$

16 3. Navigate to the folders containing your Components (if you followed the instructions in the DS Sketch3D website FAQ page, this should be C:\Program Files [(x86)]\google\google SketchUp 8\Components). Select the component you wish to replace the symbol with and click Open. The 2D symbol will now be replaced with the 3D (or 2D) component. 16

It is important to remember, when creating your CAD drawing, that you use unique symbols for each plant type. 5.

17 4. Continue this process with the remaining symbols in the model. Note that when you select a symbol to replace, SketchUp will replace all the symbols that are the same. It is important to remember, when creating your CAD drawing, that you use unique symbols for each plant type. 5. You can use the same process to replace other symbols as well such as rocks and furniture. Symbols such as pools and ponds however will lose their ability to cut the surface if brought in 17

18 this way these should be brought in through the Components browser. You can always add more components to your model as you see fit. 18

Change your view style to Wire Frame: If your Styles are not visible, go to the View menu, select Toolbars and choose Styles. In Wire Frame style you can navigate smoothly.

19 Navigation Tips If you find navigation round your model getting slow while working you can alleviate this a couple ways. 1. Keep shadows off: The calculation used to create face shadows is processor-intensive and will slow down performance with large models. Its best to keep shadows off, especially when navigating. 2. Change your view style to Wire Frame: If your Styles are not visible, go to the View menu, select Toolbars and choose Styles. In Wire Frame style you can navigate smoothly. You can switch to Shaded or Shaded with Textures, whenever you need to see the faces of you model and your components. 3. Switch your trees to 2D: All 3D trees from DS Sketch3D 3D have a 2D image of the tree ( billboard ) embedded into the component on a different layer. Open the Layers list (Window > Layers) and turn the Trees 3D layer off and the Trees Billboard layer off. 3D trees have hundreds of faces that SketchUp has to try to display. The 2D billboard is made up of one face and will make it easier to navigate. 19

4. Use 2D trees instead of 3D: The DS Sketch3D website offers a large library of 2D components as well. If your model requires lots of trees, use 2D trees, especially for existing or background trees.

20 4. Use 2D trees instead of 3D: The DS Sketch3D website offers a large library of 2D components as well. If your model requires lots of trees, use 2D trees, especially for existing or background trees. This will reduce the number of faces in the model. Presentation Options When your model is complete it is time to show your clients. This can be accomplished several ways: 1. Show the model on your computer: Bring a laptop to your client or have them come to your office and show the model right in SketchUp. 2. Export scenes as images: You can export snapshots from various angles of your model as an image file. These can be printed, ed or they can be added as raster images in your 2D CAD drawing. 3. Export an animation: SketchUp allows you to create a movie (.avi) of your model. This feature will make use of your created scenes to fly around your model like an animation. 4. Create Realistic renderings: Using one of the many rendering tools available for SketchUp you can create high quality images that can look very realistic. Note: All of these options require scenes to be set up. Scenes are basically views of your model from various angles. Scenes are very easy to create in SketchUp. 20

Improving Your Model s Appearance: Many of the DS Sketch3D plant models are made with texture

This is because of the way SketchUp handles textures with transparencies when the transparency

If you change the quality setting to Medium, the white glow around the edge disappears.

21 Improving Your Model s Appearance: Many of the DS Sketch3D plant models are made with texture images for leaves and flowers. You may notice a white glow around edges of the leaves. This is because of the way SketchUp handles textures with transparencies when the transparency quality is set to faster. If you change the quality setting to Medium, the white glow around the edge disappears. 2D models with transparencies will have the same issue. To change the transparency setting for your model, go to the Window menu and select Styles. Click on the Edit tab and then the Styles icon. 21

22 Make sure Enable Transparency is checked and change the Transparency quality to Medium. 22

Navigate to your starting point for your first scene. If you find SketchUp lagging as you move around, switch to Wire Frame style for smoother navigation.

23 Step 8: Create Scenes Before creating any scenes it is best to plan ahead, especially if you are creating an animation. Pick a logical starting point and plan your steps so you can move around the model from scene to scene smoothly. Follow these steps to create a scene: 1. Navigate to your starting point for your first scene. If you find SketchUp lagging as you move around, switch to Wire Frame style for smoother navigation. When the desired angle is achieved, click on the View menu and select Animation. Select Add Scene to create a scene. A tab will appear on the top left side of the work space. 2. Navigate to the next angle and add another scene. You can also use the keyboard shortcut [Alt+S]. Create as many scenes as you wish. 3. Once you are finished you can play an animation that takes you through each of your scenes in their order. To play an animation go to View > Animation and select Play. If you need to adjust a scene, navigate to where you wish to the scene to be adjusted to and then right-click on the scene and choose Update. 23

Exporting Scenes as Images To export your scenes as images go to the File menu and select Export > 2D Graphic In the Export 2D Graphic panel that appears, you can choose the image type (.jpg,.png etc.

This will give the scene more depth. Exporting Scenes as an Animation To export your scenes as an animation (.

24 Exporting Scenes as Images To export your scenes as images go to the File menu and select Export > 2D Graphic In the Export 2D Graphic panel that appears, you can choose the image type (.jpg,.png etc.) and if you click on the Options button you can also change the image size and other options. If your computer can handle it you can try to turn shadows on before exporting as an image. This will give the scene more depth. Exporting Scenes as an Animation To export your scenes as an animation (.avi video) go to the File menu and select Export > Animation In the Export Animation panel that appears you can change your output to images of each scene (.jpgs) and if you click on the Options button you can change the size of the video among other settings. Step 9: Render your Model for Presentation Using a rendering tool is the best way to create images of your model to present to your client. Rendering tools enhance the lighting and shadows on the models faces and textures, creating a much more realistic looking image in the end than what SketchUp can produce by itself, with a much higher resolution. See the results below the one on the right is an export from SketchUp while the one on the right is with a rendering tool: Exported 2D Image from SketchUp The same scene created by a rendering tool 24

25 There are a number of rendering tools available. Most have default settings that make them easy to use for beginners. They all have advanced settings and features that can really enhance your model when you take the time to learn them. Some are free, others are for purchase but usually have a trial available. The following are some of the rendering tools available: Kerkythea Echo A free rendering software that may be good enough for some and is good place to get introduced.
