Specify a printer to print the multiple PLT, PRN and list file (.TXT) files at one time.
You should set the file to be plotted by selecting desired plt files or prn files from the Open button on Pltplot dialog box. It's also available to save the files listed on current plot file list as a ".TXT" file using the Save list button on Pltplot dialog box, and then add all the files included in the list into current list whenever you use this file at your desire.
The plot list displays name and path of the file, the .plt file or .prn file will be displayed together with its saving path. While the TXT file will be displayed with file path.
Before batch plotting, you can set all the files in the plot list, and also selective plot part of the files from the plot list.
PLOT: Plots a drawing to a plotter, printer, or file
PLTPLOT: Batch plot your PLT files
