The bottom right is a polygon subpatched.
See how all 3 axes smooth around the corners.
I am trying to model a spline to do the same thing.ah help !!!
I can smooth out 2 Splines.even when I hi light 3 Splines only 2 smooth out.
So Can we smooth 3 Splines all at one time.
So thay all will be smooth to each other ? if not now what ?

Thanks for any and all help

Short answer: No.

To get the results you want, using spline patching, you will probably need to think more carefully about how those corners are filleted, and add at least another row of splines at the point where you want the fillet to start and end, which is rapidly going to turn into a mess.

To be honest, this is not a very good or accurate way of creating the shape you want. Sub-D modelling will give you the shape you want much faster, with greater accuracy - especially if you use a Sub Patch Weight map to control the tension on those corners.

No wasn't the answer I was hoping for.
Thanks for the info.

Don't give up just yet. What I said about filleting might be a way to go - in fact, I'd say, you need the opposite of smoothing to get a good curve there. Instead, break up the curves like this....

One thing I like to do is similar to what you did, which is to use template polys to create splines from. Theres a few plugins that will give polys a radius at the corners. One of those is called Jetto Fillet (http://www.3dfightclub.com/~jettocrack/lightwave/plugins/jettofillet/index.htm) .
Once I get the radius I want its easy to select points to create splines and they behave very well. Heres an example of what I mean. The first layer is the regular geometry. Layer 2 is the filleted geometry and layer 3 has some splines I made by picking points off layer 2.
