Ge-Terrain for Revit FAQ

NO. Google Earth is not requested in order to use Ge-Terrain. However it is necessary to use Google Maps as the Google Earth services for this type of application are no longer available.

Display Resolution Issue Solved

Previous versions of GE Terrain showed issues related to the PC display resolution when these were over 1920 x 1080. During importation of the terrain an error occurred causing distortion and skewness. The solution to this is simple and straightforward. It is necessary to set the display resolution of your PC to 1920 x 1080. This resolution setting allows you to obtain maximum efficiency and the highest quality from GE Terrain.

It is possible to edit the imported surface via the Revit commands. After surface importation the commands are automatically activated,
you will see “Modify|Topography” click on it and then on “Edit Surface” where you will be able to create, delete and move points.

The installer that ran when you downloaded this plug-in from Autodesk App store has already installed the plug-in. You may need to restart the Autodesk product to activate the plug-in.

To uninstall this plug-in, exit the Autodesk product if you are currently running it, uninstall it from ‘Control Panel\Programs\Programs and Features’ (Windows 7/8/8.1) or Control Panel > Add or Remove Programs, just as you would uninstall any other application from your system.

In this video, we are going to see how to apply a textured material to the Topographic surface.
1. Import our mesh.
2. Create a new project in Revit.
3. From the OneRay-RT menu, select Ge-Terrain
4. Click on Acquire Terrain to choose the area we wish to import. On the top right, there is a field where you can write the name of a mountain, city, address for example as well as the latitude and longitude of the interested area.Click on GO. It is important to zoom it in order to visualize the entire area to import.
5. Click on Import Surface to import the selected surface in Revit. In the window that appears, we have the google named image which we will click on to save in a any given folder, it is suggested to create a project folder.
6. Take a note of X ext. and Y ext. (we will need these later); click on Terrain Create to create the topographic surface in Revit. As Ge-Terrain works in the Decimal Metric System, it is necessary (if we are working in a different one) to convert the project to this system. Once the texture has been applied, we can convert back.
7. We are now creating the textured material to apply to the topographic surface. Click on material, choose new material, click on appearance and select image, in the window that appears, we are choosing the image we have previously saved.
8. To edit the image, go to the scale section and click on the chain icon. Write the X ext. measurement
in the width field and Y ext. measurement in the height field. Select NONE in all fields of the repeat section.
9. Click on done. Back in the material browser, all we have to do is click on ok.
10. At the bottom of the working area, set Fine for level detail and Ray Trace for visual style to obtain the rendering of our project.

General Usage Instructions

1. Launch Revit and choose Ge-Terrain in the OneRay-RT menu
2. In the window that appears choose acquire terrain to start interested area selection procedure
3. Here, on the top right you can insert the location you want, or select it directly on the map. On the top left you can insert the number of samples and click on import surface.
4. Click on create terrain to complete the procedure and thus create a topographic surface in Revit.

Now it is not possible to import buildings as Google does not envisage this function.
