AutoCAD 2013/2014 DWG Format

[#1]

I'm currently running Autocad 2013 and I can make sense of how to import ECW files. I'm very new at working with these kinds of files.

[#2]

AutoCAD doesn't natively read ECWs. If you install the Raster Design object enabler that should do it.

[#3]

Raster image files in the ECW format are natively supported in AutoCAD (since version 2012). Just specify the ECW file in the IMAGEATTACH command. See:

Great! That worked to import it. But, as I said I'm new. My employer said that autocad and the photo itself are smart enough to imort properly according to it's georeferencing data attached to the image and would also automatically scale it. Right now when I imported the photo, it did indeed import but it asked me where I want to place it and what scale factor, two question which I thought it would already know.

I just have Autocad 2013. Do I have to have Civil 3D and it's map functionaility to do this?

Thanks

Georeferenced images are supported in AutoCAD Map 3D, Civil 3D and Raster Design only. But you can try our free utility GeoRefImg to position images according to their gereferencing "world" files (e.g. EWW) in plain AutoCAD - see:

Great! I installed it. I pasted the folder in my plugins area for Autodesk then reatrted my computer. Once I insert my ECW file I found the GEOREFIMG button under the CAD Studio tab. So I selected it and it tells be to "GEOREFIMG Select image(s) to reposition:" so I selected the image and it appeared to do nothing. Didn't resize it at all.

Are there any messages on the command line? Are you sure you have the georeference world files (.EWW) stored with your .ECW files?

Once I selct the object (map image) to apply the georefimg to and hit enter, the command line says nothing, almost as if Autocad assumes it's done it's job.

I've looked in the folder where the ecw file is located and I don't see anything that shows eww as an extension.

Thanks for the help. I haven't been able to find any good tutorials on how to understand this stuff. I'm just trying to learn now. Boss handed me these images and said "Here. Learn how to insert this stuff into a cad drawing".

[#9]

Sorry! I just realized how to scroll up in my command line and it did say ">GEOREF - FILE NOT FOUND!"

Is this a flaw in how the supplier of the imagery supplied the photos? Should they have included an eww file as well? I guess my layman's understand wa sthat the image itself contained the data it needed.

The problem is that GeoRefImg supports georeferences in separate "world" files (the more usual scenario), not embedded location data stored inside raster files (e.g. in some types of TIFF and ECW).
