Hi there,
We have some clients that are using version 2011 and we are using 2014. The landxml we made for them was too big for them to import. My boss made a DEM GEOTIFF to send as it was much smaller.
The client has called me and asked me how the heck does he import the file as he as never worked with them. I have a computer with a 2012 installation, but it's corrupt, none of the MAP utilities work.
Can someone tell me how to instruct my client to import this file.
I have searched the google and found nothing.
Thanks in advance.
He can type Mapconnect at the command prompt. Once the dialog appears, use the Add Raster Image or Surface Connection to attach the GeoTIFF.
thanks for the reply. I tried that and it doesn't produce what I am looking for.
It was actually easier that I assumed. You just create a surface the normal way you would, then in the definition tab in toolspace, right click DEM files, change file type to .tif and whamo!
The only problem I am having now is it is coming in 34 feet to the south.
I am creating this file from a drawing, then importing it into the same drawing and it's applying a shift by itself. The drawing and DEM file are in the correct coordinate system.
The weird thing was, when I used the method you suggested (mapconnect), it brought it in the right place, but it wasn't an autocad surface, just an image of a surface.
Check your drawing settings and be sure you're using US Survey Foot, not International Foot. That could cause that 34' bust.

Civil 3D 2013 and newer have a known issue where the MAPIMPORT (not the FDO method) does not read a GeoTIFF's header correctly. It ignores the UNITS field. This has caused all 111 of our county aerials to be imported as meters instead of US Survey feet. We have to turn off the coordinate system, import the image(s), then turn the coordinate back on in order to use our color GeoTIFFs. I wonder if the import a DEM uses the same code methods which could cause this issue?
That shift sounds like it might be caused by having one file set to US Foot and another file set to International Foot.
Or have Survey set to one while the drawing is set to the other.
This came in my google search, and it helped a lot.
Thanks so much (Although this is more than 3 years late :D)
