We used to talk about how Import an image from Google Earth to AutoCAD now let's see how to import the surface and make this image is in color and can hunt on this surface 3D.
The trick is the same as We saw with Microstation, Creating a material and even solves the problem that the image is grayscale.
1 Select the Image in Google Earth
It is required to open Google Earth, deactivate the terrain layer, the north compass and the orthogonal view. The better approach we have, we can obtain a better resolution, as we had discussed in the previous post.
2. Import the 3D mesh
When opening AutoCAD, you should not minimize the GoogleEarth window, nor close it, but keep the maximized view that you want to capture.
Then we activate the icon indicated on the right, through the text command “ImportGEMesh”
In case of having AutoCAD Map3D or AutoCAD Civil 3D, the mesh will hunt georeferenced between the coordinates of the box of Google Earth (as long as a projection system is defined for the drawing in use) and the image will hunt in this box.
If you do not have any of the two previous programs, but only AutoCAD, or Architectural, the option to indicate the lower left corner will be activated and the file will be inserted with the measurement units in a mesh (3D mesh) of 32 by 32 squares . The system will immediately ask you for the corners of the image and rotation.
3. View the image on the surface
If what you want is to see the image captured on the surface, select the “realistic” option from the “3D modeling” panel.
Then select some views that facilitate the isometric visualization.
4. Putting the image in color
Although the image is imported in grayscale, for Google's sake, if you use the trick of converting the image into material you can get it in colors as seen in the following steps:
- In the image displayed in Google Earth, we save it with the option file / save / save image
- Then from AutoCAD, in the material panel, we assign the image as material
- In the units of scale we assign you to fit (fit to gizmo)
- In the tile options (U tile, V tile) we assign 1
- In the offset options between mosaic images (U offset, V offset) we assign 0
- In the rotation we assign 0 Now we assign that material to the mesh through the "materialmap" command with the "planar" option And that's it, we change the mode from "realistic 3D view" to shaded mode (shademode)
5. Installing the extension
To install this application Should be downloaded from the AutoDesk labs page. Once the file is unzipped, it is executed and the installation path of the AutoCAD version where we want the add-on to be installed must be chosen, in case of having more than one program, an installation must be made for each one.
Although it is a process authorized by Google Earh, the image is in grayscale and not in color, by Google provisions.
This tool only works with 2008 versions, both AutoCAD, AutoCAD Architectural, AutoCAD Civil 3D and AutoCAD Map 3D.
In the case of AutoCAD Civil 3D 2012 and 2011 it is already integrated. If you don't have Civil3D, you can do it with the Plex.Earth plugin
