Drawing links and nodes with appropriate widths can be better controlled if you zoom into a window. The line width or node radius will remain relative when you window out. By being in a tighter window you will have more control.
We have been using screen capture routines to make presentation slides or overhead transparencies. It is much easier to relate your important information using these visual aids than it is to bring people in to see your computer.
If you are not sure what is in your .DAF (Display Attributes File) before plotting, turn link and node widths and text on and then REDRAW. This will display the contents of the .DAF. Remember that REDRAW is always the lowest item in the upper dark blue menu bar.
Keep your link volume counts in an .LVX (Link Volumes) file. Always clear the volumes before performing an assignment (see section 1.2.8.R) or the assigned volumes will be added to the counts. This makes for easy comparisons during calibration.
