Pack and Go Part and Linked Equation Example (C#)

This example shows how to determine if a part document includes any equations and whether those equations are linked files. The example also shows how to add the part document and any linked equations to Pack and Go.

// Preconditions:
// 1. Verify that the specified part and equation documents 
//    exist.
// 2. Verify that c:\temp exists.
// 3. Open the Immediate window.
// Postconditions:
// 1. Opens the specified part document.
// 2. Adds the part and linked equation documents
//    to Pack and Go and copies the files to
//    c:\temp.
// 3. To verify, examine c:\temp.
// NOTE: Because the model is used elsewhere,
// do not save changes.
