Run the Swap/Update Block tool and select Update in the second section. Make sure the option to keep old attribute positions is NOT checked and then select your block. This will remove and then redefine your block. Type ADC at the command line in the drawing which your new block is going to be inserted into. Expand the tree of the drawing which has your new block in and right click on the block and choose redefine. Insert the edited block and then run the ATTSYNC command. Choose "Select" from the command prompt, click on the new block, hit enter to accept and the old blocks should update. Run "Swap/UpdateBlock" to refresh the block already loaded in the drawing. Then the new data will appear in the blocks on the drawing. Enter FIELDEVAL at the Command line. Set the variable to a sum containing the value 16 (bitcode for updating on regeneration). Alternately, it is possible to manually update the fields by using the command UPDATEFIELD.
