Saving time is what customization is all about, Harry said as he showed me Tip #1951 (Layer List), by Theodorus Winata. He must work with a lot of layer names, because this utility defines a long list of layers and attributes in a CSV file, a simple comma-delimited text file that you can manipulate with most spreadsheet programs. This utility reads a CSV file into AutoLISP. Data is stored by column. Each row is a different layer- column one contains the layer name, column two the color, column three the linetype (use CN for Continuous in the spreadsheet), and the last column the status of the plot style (a value of Y indicates Plot for the response to Plotting Preference). This solution is elegant when you're working with lots of different standards that need revisions on a regular basis.
