Use the Manage Lookup Tables command while editing a family when you need to import, export, or delete a lookup table.
Export a lookup table when you need to create an external file containing the data from a conduit or pipe family so that you can update it. Import a lookup table when you need to add or change the data stored within a family file for conduit or pipe. For example, you can export a lookup table to a spreadsheet file, edit the data within the file, and then import the table to update the data in the family.
You can delete a lookup table that is no longer needed as long as the data is not being referenced by the parameters in a formula.
