Insert a Composite Curve Example (VBA)

This example shows how to insert a composite curve using two sketches of splines.

'--------------------------------------------------------
' Preconditions:
' 1. Verify that the part document template exists.
' 2. Open the Immediate window.
'
' Postconditions:
' 1. Opens a new part document.
' 2. Creates a sketch of a spline.
' 3. Creates another sketch of a spline.
' 4. Inserts a composite curve using the sketches created
'    in steps 2 and 3.
' 5. Prints the number of joined entities in the composite
'    curve to the Immediate window.
' 6. Examine the Immediate window.
