Run SOLIDWORKS Commands and Synthesize Mouse Events Example (C#)

This example shows how to run SOLIDWORKS commands and synthesize mouse events.

//-----------------------------------------------------------
// Preconditions:
// 1. Verify that the specified part document to open exists.
// 2. Click Tools > Options and click to clear the Stop VSTA debugger 
//    on macro exit check box, if it is selected.
// 3. In the IDE, right-click the project name in the Project Explorer,
//    click Add Reference, browse install_dir\api\redist\CLR2, click 
//    SolidWorks.Interop.swcommands.dll, and click OK.
// 4. Open the Immediate window.
//
// Postconditions:
// 1. Opens the specified part document.
// 2. Fits the model to the graphics area.
// 3. Moves the mouse.
// 4. Changes the view orientation to *Front.
// 5. Select an edge on the model.
// 6. Left-click anywhere outside the model in the graphics area.
// 7. Examine the Immediate window.
// 8. Click Stop Debugging in the IDE.
// 9. Click Tools > Options and click to select the Stop VSTA debugger 
//    on macro exit check box, if it is clear.
