With the CADstudio BLegend utility you can easily create a legend (BOM table) of blocks used in your drawing (including icons - thumbnail previews of the blocks).
Load the LISP utility with APPLOAD and start it with the BLegend command.
Since version 1.1 you can select block names and layers to include in the resulting table. Since version 1.2 you can schedule selected block references only. Then pick the top left corner of the legend table and specify its width. The legend will list all blocks in the current space (model/paper), their names, descriptions (see the block editor) and count. The legend is created in the current table style. You can then customize it (e.g. remove a column).
The labels are created in the current locale language (CZ/EN).
Legend (in Czech) created from the DWG block library Animals
