Create Curvature Continuous Variable Fillet Feature Example (C#)

This example shows how to create a curvature continuous variable fillet feature.

//-------------------------------------------------------------------------------
// Preconditions:
// 1. Verify that the specified part template exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Creates a part with a variable fillet feature with curvature continuous.
// 2. Gets whether the variable fillet feature has curvature continuous set.
// 3. Examine the graphics area and the Immediate window.
