This command renames layers using a lookup table with pairs of
original and renamed layer names. This command can be used to
convert the layers for a drawing from another source to match your
layer standards. The layer names are entered in a spreadsheet. The
Add, Insert, Delete and Sort buttons work on the spreadsheet rows.
The Report button makes a report for the layer assignments. The
SaveAs and Load functions store and recall the layer assignments to
a .LTF file for sharing the settings or keeping different sets of
layer assignments.
