Get eDrawings Data Example (C#)

This example shows how to get eDrawings data from a SolidWorks document using the SolidWorks Document Manager API.

//---------------------------------------------------------------------------

// Preconditions:
// 1. Read the SolidWorks Document Manager API
      Getting Started topic and ensure
//    that the required DLLs have been
//    registered.
// 2. Copy and paste this module into a C# console
//    application in Microsoft Visual Studio.
// 3. Ensure that the specified document exists
//    (or point to another document that contains
//    eDrawings data).
// 4. Add the SolidWorks.Interop.swdocumentmgr.dll
//    reference to the project:
//    a. Right-click the solution in Solution
//       Explorer.
//    b. Select Add Reference.
//    c. Click the Browse tab.
//    d. Load:
//  <SolidWorks_install_dir>\api\redist\SolidWorks.Interop.swdocumentmgr.dll
// 5. Substitute <your_license_code> with your
//    SolidWorks Document Manager license key.
// 6. Compile and run this program in Debug mode.
//
// Postconditions:
// 1. Inspect the error code in the Output window.
// 2. The eDrawings data is extracted to a temp file
//    in C:\temp.
