Could you please help me out with this question. We use your LiveLabel  for room areas in Autocad 2006. The area is written into block attributes and the blocks are then exported with Excellink. Very nice programs.Now, the rooms are drawn in millimetres but I need LiveLabel to show the area in square meters whithout any decimals.Thank you.

Such conversion can be done with the "postprocessing macros" in LiveLabel. In this case, use the DIESEL macro:
$(rtos,$(/,%NPROPERTY,1000000),2,0)
See also the LiveLabel homepage for other examples of postprocessing macros.
