Deleting and Importing Alignments
If you do not want to view an alignment in your drawing at all times,
then you can do the following:
■
Turn off or freeze the layer that it is on.
■
Erase the alignment using the ERASE command.
■
Use the Delete command on the Alignments menu.
Erasing the alignment does not remove the alignment database
definition. To redisplay the alignment in the drawing, import the
alignment.
Using the Delete command, you can delete the alignment from the
drawing only, the equivalent of using the ERASE command, or delete
the alignment from the database as well. If you delete the alignment
from the drawing, then you can use the Import command on the
Alignments menu to import it back into the drawing.
If you delete the alignment from the database, then you can redefine
the alignment from the drawing objects, if necessary. However, if
you delete the alignment from both the drawing and the database,
then you cannot restore the alignment.
