Replaces blocks and attributes based on mapping values set up in a spreadsheet.
If you select an existing spreadsheet the block replacement automatically begins. If the spreadsheet file does not exist you are presented with the option to create the spreadsheet framework for the block/attribute mapping.
If a spreadsheet was not found, on the Spreadsheet Not Found dialog box, click OK to run through the drawing set of the active project. Fill in a blank spreadsheet with extracted block names and attributes. Only the first column of each of the sheets are filled in. You can then add the block/attribute mapping information and then rerun the command using the new spreadsheet.
