Hi, 1. I would like to write typecodes in AutoCAD drawings (e.g., typecodes for commercial products). I would like to do this in layer with clear annotations pointing to specific parts in the drawing, so that the layer can be hidden if I don't want to show the codes. 2. Extract all & only typecodes from the drawing to Excel (or even text) file. This is to make a BOM of the parts with typecode. Do you know any methods to do this? Thanks in advance, Srinivas
