for complex drawings.

Assignment

Pause this tutorial and do this assignment.


Create two routes from Home to the School Campus in the RouteMap drawing.


Create each route

  • on a separate layer
  • so that they can be printed
  • as two different maps
  • each displaying only one route.
Let us now learn how to export the file as a PDF and also password protect our Draw file.
Switch to the file “Route Map”.

Main menu >> File >> Export to PDF

First let’s save the Draw file “RouteMap” as a PDF.

From the main menu, select File and click “Export as PDF”.

Click General Click the “General” Tab.
Select Range >> select All Under “Range”, let us select “All” as we are converting all the pages in the Draw file to PDF.

This is the most common format that is used for compression.

PDF options dialog box >> Click “Initial View” Next, click the Initial View tab.
Point downwards in the dialog box to the various default settings. We will keep the default values displayed in the dialog box.
In PDF options dialog box >> Click “Links”. Now, click on the Links tab.
