Raster / Vector File Associations in AutoCAD R14 and 2000
History: The GTXRaster CAD Series displays and edits scanned raster
images in a vector design environment, AutoCAD. It is often used for hybrid
design work using scanned archival paper drawings. Typically, vector files are
overlayed on top of a scanned raster file with full editing
ability for both raster and vector. This includes scaling and positioning
of any of the file elements. Some tricks are required to save changes to
the hybrid (raster/vector) file set while preserving the scale and position
of the raster file for reuse when the files are needed in the future.
AutoCAD has taken control of the image files in AutoCAD 14 and 2000.
They have an image management function which you may reach by typing
the word image at the command line.
An example of the Image Manager is shown below. To keep hybrids under
control, map all users network connections the same drive letters.
This is important because if users are mapping a drawing file area to different
drive letters, then a drawing file saved by one user will contain images that
point to a path that is invalid for the other user. The raster file
is not found in the path that was defined in the drawing and AutoCAD displays
an empty proxy frame instead of the image. The Image Manager will display the
original image path.
You can correct an empty proxy object using the 'Image found at' area
of the Image Manager. In general, changing the storage path of an image will
require a resave of the dwg after the image dialog box features have been made correct. For
more information do a search for the word image on the Autodesk web site.
The AutoCAD Image Manager may be accessed by using the "image" command from
the command line:
