A raster image that was part of a drawing set fails
to display
The association between an AutoCAD DWG drawing file and
it's attached objects will be defeated if the attached object's file name or
file storage path has changed since the DWG drawing was created. Raster image
file paths and file names are defined in a drawing once those objects have been
attached to a drawing and the drawing is saved.
Here is an exercise that displays how an attachment
failure looks and how it should be corrected. Assume that a drawing named
Drawing1.dwg was saved with an image attachment named GTXlogo.tif. The image
appeared in the display of Drawing1.dwg like this when the drawing was created and
saved.
During the history of Drawing1.dwg someone had changed the
name of it's attached GTXlogo.tif file name to GTX_logo.tif. This defeats the
association between Drawing1 and GTXlogo.tif. Opening Drawing1 will result in
the following display that defines the size, position, file path and file name
of the image that was defined when Drawing1 was created and saved.
Use the AutoCAD Image Manager or External Reference
Manager to correct the association between drawing and image files. The Image
Manager is the standard interface for attaching, detaching, or redefining
AutoCAD supported image files in AutoCAD 2006 and prior versions. The Image
Manager is still accessible in the GTXImage CAD Series V11.5 and AutoCAD 2007 and later versions by use of the
CLASSICIMAGE command on the program's command line.
1. Highlight the image name, in this case GTXlogo
2. Use the Browse button to find the image file that was
renamed, in this case GTX_logo.tif.
3. Use the Save Path button, select the OK button to close
the Image Manager, then SAVE THE DRAWING.
THE CORRECTION IS NOT COMPLETE UNTIL THE DRAWING IS SAVED
A similar procedure is followed using the External
References manager.
1. Highlight the Reference Name, in this case GTXlogo.
2. Click on the Found At bar of the Details pane.
3. Click on the dotted frame at the edge of the Found At
bar to initiate a Browse window titled Select Image File.
4. Find the image file that was renamed, in this case
GTX_logo.tif, select the Open button.
5. Close the External References manager then SAVE THE
DRAWING.
