# Insert Point Example (C#)

This example shows how to insert a point in a drawing document.

    //--------------------------------------------------------------
    // Preconditions:
    // 1. Create a C# Windows console project.
    // 2. Copy and paste this example into the C# IDE.
    // 3. Add a reference to:
    //    install_dir\APISDK\tlb\DraftSight.Interop.dsAutomation.dll.
    // 4. Add references to System and System.Windows.Forms.
    // 5. Start DraftSight and open a document.
    // 6. Start debugging the project.
    //
    // Postconditions: A message box pops up when a point is
    // inserted in the drawing document. A SimpleNote is also
    // added to the drawing that identifies where the point was inserted.
