Create Drag Arrow Manipulator Example (C#)

This example shows how to create a drag arrow manipulator, which is called a handle in the user interface.

//---------------------------------------------------------------------------
// Preconditions:
// 1. Open a part or assembly and select a face.
// 2. De-select Tools > Options > Stop VSTA debugger on macro exit.
// 3. Select Project > Add Reference > .NET > SolidWorks.Interop.swpublished.
// 4. Rename the namespace to match the name of your C# project.
// 5. Open an Immediate window.
//
// Postconditions:
// 1. A unidirectional drag arrow manipulator or handle is created on the selected face.
// 2. Drag the handle to another location. The first time you drag the handle,
//    IDragArrowManipulator::FixedLength is set to true,
//    and the origin is moved in the direction of the drag. For second and
//    subsequent drags, IDragArrowManipulator::FixedLength is set to false,
//    and the origin is not changed.
// 3. When you drag the handle a ruler displays.
//    IDragArrowManipulator::ShowRuler is true.
// 4. When you drag the handle past length = 0, the handle flips direction.
//    IDragArrowManipulator::AllowFlip is true.
// 5. Inspect the Immediate window.
