The Blend Tangent to Surface feature isn't used very frequently. It was never very "big" to begin with but now that the standard Draft Tool has become much more powerful, it's used even less.  There are some notable capabilities of this feature but there are also some limitations. This truly generates only surfaces, not solid geometry. You'll need to add other features such as Thicken or Offset and Solidify to create solid geometry.

 

Since you asked, here are two examples. There are three main options to this feature... I've demonstrated two of them. Hope this is what you were looking for! Click each of the images below for a much larger version that's easier to read.

Correct AnswerRe: Blend Tangent to Surface

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!
