So how did I do it? I'll answer that shortly. Before going into the steps, be aware that this blog is not intended as training. It is intended to show you capabilities of AutoCAD Map. You may have to "crack the manual" and do a little research. It will be worth it, because you will get spectacular results!
I will publish a city boundary and flood plane then drape it onto a surface. Start the publish KMZ process from the publishKML button:
Importing the surface from Google Earth.
Before importing from Google Earth, you must have it open and zoom to your area of interest. You also need to make sure you are viewing in plan view. For this next step, I will be using a new empty drawing. You can use an existing project if you'd like. It is important to note that you must be working in a defined coordinate system otherwise nothing will geo-reference correctly.
The imported mesh with a new material:
The aerial photography is imported as a material. The image will always be black and white. You can update it to a color image by doing the following steps.
- Close the drawing and save it.
- Use the google earth export image and overwrite the image referenced by the material (Sorry you'll have to crack the manual on this one. This is an AutoCAD skill not AutoCAD Map.)
- Re-open the drawing. It should now have the color image linked to the material.
Viewing the surface in 3D.
Note that you can see the surface "grid". To turn this off, edit the Realistic visual style and change the Edge Mode to NONE:
Here are a couple of close-up views of the finished product from different perspectives:
