I am using Architectural Desktop 3.3. I am haveing alot of problems with the plot stamp in metric drawings. All the setting in the "Plot Stamp" are correct. I know this, because it prints just fine in english units. However, the plot stamp disapears when the "Printable area" is set to "mm" instead of "inches" in the "Paper size and paper units" area of the Plot window. It is necessary to set it to "mm" in order for the pen weights to print properly. Any thoughts?
