Surface help 2

[Miyamoto12]

What's the easiest/best way to accomplish what I'm trying to do here? See pic, All I want to do is take park of the surface geometry, and create a casting riser out of it that ends up in a rounded sphere. I want a smooth transition, from the part surface (the cross) to a sphere. The left is my result, which looks like garbage and on the right you see the surface I'd like to connect the sphere to, just thickened. Thanks for your help! NX 10

Quick Example...
Of course you need to match this to your base sketch...

Or with a complete smooth transition....

Thanks fir tour help. It really helps coming from a sketch vs an extrude.

Try "through curves" command. It will give you even better shape if you adjust tangency/curvature to sphere face.

With TC, you always need to connect the bottom shape with the top shape with guide lines, correct?

No, that's Through Curve Mesh. Through curves will work with two curve sections (no guide lines). If you want the result to be tangent, you will need existing surfaces to reference (i.e. you would need to make the spherical cap surface before the through curve surface).

great thanks!

Here the result of using Through curves with G1 tangency to the sphere....
