I have a recurring problem in Civil 3D 2011. From time-to-time, I have to attach to an image file (ie - survey plan) and draft on top of it. In the case of the current work I'm doing, I am making revisions to an existing drawing set. That said, we need to keep the original work, so I've saved the drawings to a new folder with a new name (indicating the date of my revisions). I have set "relative pathways" on the images I've inserted, and the drawing (technically) should go fishing for the images starting at the new save location. When I open the drawings however, the images are missing, and all I see is a link indicating where the images "should be". This should not be happening and it's very frustrating!! In ArcMap, this type of problem is easy to fix. Does anyone know how to fix this? I know this is a GIS community, but I figure some of you must use CAD too. I would greatly appreciate any feedback. Thanks
Brad provided the following suggestion and it resolved my issue:
"Keep the images in the same "relative" folder with your drawing. If you save as you would need to copy the image to the new "relative" folder if you want to use relative paths"
Thanks a million!! This will save me hours of frustration!!
Relative pathways as far as I understand does not "fish" for locations.
To change the path you can use external references palette and edit the path to the correct one.
The other option is to have 1 folder location for all the images (ussually not recommended) and hard path that into your autocad profile. Or keep the images in the same "relative" folder with your drawing. If you saveas (the dwg) you would need to copy the image to the new "relative" folder if you want to use relative paths
Another option to change/repair xrefs is to use the Reference Manager. This is a standalone program that is installed as part of AutoDesk. It allows you to repair paths to external references .Think of it as the equivalent of the ArcCatalog repair functionality.
You said "... saved under a new drawing name, and I did so in a new folder within the project directory..." If this new folder has a different relative path to the images the xref will break. Check your folder nesting level. Also double check that the xref is using relative paths and not a full file path. too for the DOS dots in the path name.
The conventions for specifying a relative folder path are as follows:
\ Look in the root folder of the host drawing's drive path From the root folder, follow the specified path .\path From the folder of the host drawing, follow the specified path ..\path From the folder of the host drawing, move up one folder level and follow the specified path ....\path From the folder of the host drawing, move up two folder levels and follow the specified path
Note If a drawing that contains referenced files is moved or saved to a different path, to a different local hard drive, or to a different network server, you must edit any relative paths to accommodate the host drawing's new location or you must relocate the referenced files.
