Get UV Parameters for XYZ Location Example (C#)
This example shows how to use IFace2 and ICurve interfaces
to get the UV parameters from the XYZ location.
//---------------------------------------------------------------------------
// Preconditions:
// 1. Open
public_documents\tutorial\cosmosxpress\aw_hook.sldprt.
// 2.
Verify that Tools > System Options > Options > FeatureManager > Solid Bodies
// drop-down selection is Show.
// 3.
Expand the Solid Bodies folder and select Split Line1.
// 4. Open the Immediate window or modify the macro to write the output to a
file.
//
// Postconditions: Observe
the output in the Immediate window.
