先在ArcGIS导出到SU，在SU中画好，再导入ArcGIS。
1. In ArcMap, use the Select tool to select the building footprints (or other features) that you want to export into SketchUp as a geocontext. Click on the “Export to SketchUp” icon that you added to the toolbars. 2. You’ll be prompted to provide a name and location for a new SketchUp file, and then a new “Items to Export” window will open. It will show you what Feature Classes are selected to export, and give you a chance to also select a TIN – don’t bother with the TIN for now. Make sure the “Launch SketchUp after export” box is checked, and click on OK. 3. SketchUp will fire up. You probably won’t see your data; click the “Zoom Extents” icon to see all your data. Your building footprints will appear as shaded polygons. 4. Use the “Select” tool to click on footprint that you want to build a model upon. You’ll find that a yellow box highlights around the footprint. This is because the features have been imported as “components”. To make them where you can edit them, right click and choose the “Explode” option. BANG! Your computer just blew up! Just kidding…. 5. Use SketchUp to build a 3-D model on the building footprint (sorry, I’m assuming you have already learned how to use SketchUp!). Repeat steps 5 and 6 for each building. 6. When you’re ready to export, you’ll need to change your models to components. Triple-click on a building model (which should select the entire model), then right-click and choose “Make Component”. You’ll be prompted to enter a name for the component. Repeat this for each building. 7. At this point, decide if you want your buildings exported as individual features (which would allow you to assign attributes, such as building names, to each building) or as a single feature comprised of several buildings. Use the “Select” tool to select however many buildings you want to include in the feature, then go to the “File” menu and choose “Export” -> “3D Model…”, and make sure that the “ESRI geodatabase” is chosen as the Export Type. Browse to a location, and then enter a name for a new ESRI Personal Geodatabase. 8. A new window will open up, asking you to select a feature class. As this is a new Geodatabase, you’ll need to click the “Create…” button to define a new feature class. No spaces or non-standard characters in this name, please! Click OK. 9. When you’re back at the Select Feature Class dialog box, make sure both checkboxes are checked, and click OK. Another dialog box will open, allowing you to “assign field values”. This is where you can create new attributes and assign values, such as building names, but let’s not bother this first time. Click on OK. Finally, go to ArcScene or ArcGlobe and click on the “Add Layer” icon. Browse for your new Geodatabase, and select the feature class that you created in SketchUp. Your SketchUp model should now appear in your GIS!! |
