Shape File Grouping

Create a shape file grouping on the Database menu: .

This creates a dBase table with the shape files to plot, the order of plotting, and the symbology to be used.

Plot grouping.

To adjust these parameters,  select the Modify, Shape File Grouping menu choice.  This will open the dBase table which indexes the files.

There is a FILTER field and a PIXEL_SIZE field in the data base with the grouping.  You can apply a filter before plotting a shape file, and set a map pixel size beyond which the file will not be plotted--if the pixel size is bigger than specified, plotting will not occur.. 

Example plot highways in the US.
