Before we saw how to do it with manifold, ArcGIS, and well we were surprised that with the popularity of AutoCAD did not reach a good negotiation with Google to do it too. Let's see the good, the bad and the ugly of this negotiation:
... THE GOOD ... is easy enough
Choose the deployment in Google Earth
For this, what you have to do is have Google Earth open, deactivate the terrain layer, the north compass and the orthogonal view. It must be remembered that the better approach we have, we will be able to obtain better resolution but it is also true that a greater number of mosaic images will be necessary.
Importing the image from AutoCAD
Being in AutoCAD, you should not minimize the window of GoogleEarth, nor close it but keep the view maximized because what the program does is capture the stream In use.
Then in AutoCAD we use the icon indicated on the right, or we activate it through the “importgeimage” command bar
If you have AutoCAD Map3D or AutoCAD Civil 3D, the image will be geo-referenced between the coordinates of the Google Earth box (as long as a projection system is defined for the drawing in use)
If you do not have any of the two previous programs, but only AutoCAD, or Architectural, the option will be activated to indicate the two corners of the image and the rotation angle as if we were using the raster manager. So in advance it is appropriate to have the corners of the quadrant indicated as shown above in a post of georeferencing of images from Google Earth to the evil.
Installing the extension
To install this application Should be downloaded from the AutoDesk labs page, in the same compressed file comes a version for AutoCAD 2007, although this one only serves to publish kml models from AutoCAD to Google Earth.
Once the file is unzipped, it runs and you must choose the AutoCAD installation path where you want the add-on to be installed, if you have more than one program, you must install each one.
… THE BAD …
Although it is a process authorized by Google Earh, the image is in grayscale and not in color, by Google provisions. Although there will be those who manage like this As in the case Of the 3D mesh licking it as material.
Then this imported image is stored in the same folder where the dwg file is stored, with extension .jpg and taking the first letters of the name of the vector file ... although it is a jpg with georeference properties.
The pixel size is the resolution of the displayed screen, so the closer the capture is, the smaller pixel sizes will be found because the file only recognizes the coordinates of the frame and stretches to that dimension.
- It is a laboratory tool, AutoDesk does not assure if including it in the next version will be free ... we hope so
- Because it is a laboratory version, it is offered “as is”, but well, AutoCAD has always been like this and in the case of Google, everything has been Beta.
- This tool only works with 2008 versions, both AutoCAD, AutoCAD Architectural, AutoCAD Civil 3D and AutoCAD Map 3D.
- It only works with a license Google Earth Pro, Apparently, so either you loose $ 400 worth that license or you patches the eye.
... Anyway, it seems that I will prefer to continue doing it with manifold, Because it only cost me $ 245 that I paid.
Another tool that does this, and that surpasses it because the image comes in color, with greater precision and in mosaic, En Plex.Earth
