Abstract: The invention provides a method and system for displaying the internal functions of a block. A user identifies a selected block having a block identifier. A data file having a plurality of drawing files is searched, using the block identifier, to identify a matching drawing file that is associated with the block identifier. The matching drawing file is scanned to identify special character items in the matching drawing file. Each special character item that is identified in the scanning is associated with a graphics item. Each special character item that is identified in the scanning is then stripped from the matching drawing file to generate a modified matching drawing file. A display is generated based on the modified matching drawing file and each identified graphics item representing the internal functions of the block.
