replaces key column in Release 14; link template replaces link path name; and label
replaces displayable attribute. You also need to create a configuration file that
points to the data source referenced by the legacy links.
When you open a drawing that contains legacy links, the program attempts
to perform an automatic conversion of the legacy information. If, for example,
you open a Release 14 drawing that contains links that point to a data source
with the structure db3.ase.db3sample.computer(com), the program attempts to
establish an exact, one-to-one mapping of the data source components.
In some cases, the legacy data source might not match exactly how the data
source is configured. For example, the legacy data source might specify a
catalog that isn't specified in the data source. If the automatic link conversion
is unsuccessful, you can use the Link Conversion dialog box to establish a
mapping between the legacy and new data sources. You can also use the Link
Template Properties dialog box to specify new data source parameters for a
selected link template.
During the conversion process, the data source mapping information is written
to a file called asi.ini. You can manually edit the conversion mapping
information specified in this file, if necessary.
NOTE The program attempts to automatically convert legacy links only for data
sources that don't have mapping values specified in the asi.ini file. Once you have
specified conversion mappings for a particular data source, the program uses the
settings specified in the asi.ini file for any additional legacy drawings you open
that contain links that reference this data source.
Save Links to Earlier Formats
Links that you have created in AutoCAD 2000 and later can be converted to
Release 13 or Release 14 links. AutoCAD 2000 and later links cannot be
converted to Release 12 format. When you use SAVEAS to save a drawing in
the current format that contains links to Release 13 or Release 14 format, the
links are automatically converted to the appropriate drawing format. You
must specify a conversion mapping as described above.
To convert Release 13 and Release 14 links
1 Click Toolsmenu Palettes DbConnect.
2 Click DbConnect menu Link Conversion.
3 In Old Link Format, do all of the following:
Select R13/R14 Link Format.
