Save File as PDF Example (C#)

This example shows how to save multiple drawing sheets to a PDF file.


// Preconditions:

// 1. Specified drawing document to open exists.

// 2. The folder (c:\test) to which to save

//    the PDF file, exists. If it does not exist,

//    create it or change the path to one that

//    exists on your system.


// Postconditions:

// 1. Specified drawing document is opened.

// 2. All but the last drawing sheet are saved to an array.

// 3. The array of drawing sheets are saved to a PDF

//    file called foodprocessor.pdf.
