Hi Saravanan...
I'm happy to share the models. They're attached below. These are just example parts created to allow me to demonstrate the feature. They aren't "real-world" items. If you have a real part and need help creating the feature, you can upload it and I'll take a look at it. This assumes, of course, that it's not a proprietary piece.
There are 3 files.
blend_tangent1.prt - Demonstrates the curve-driven blend tangent draft surface (from example #1).
blend_tangent2.prt - Demonstrates the constant angle blended draft OUTSIDE surface
blend_tangent3.prt - Demonstrates a THIRD type of Blend Tangent to Surfaces. I did not show this example in my slides, but this shows how to do a constant angle blended draft INSIDE surface. Notice in this example I also added a Solidify feature to show the resultant geometry.
Use the model player (Tools>Model Player) to interrogate this part and help you understand the process.
Thanks!
