• The output layer ordering, where the layers on top print over the layers on the bottom.
• Gives you the ability to copy layer names to multiple positions within the settings. The copied layers can also be rendered differently to the original layer to produce effects such as cased roads from the one line.
• You can also use the cad order as shown by the cad program.
• You can also set up to use color order for the output.
• you can define and save any number of settings.
