Hi all,
I’m strugling with what it looks like an easy surface.
And probably easy to do if you know how.
These are 3 srf’s and I want it to be one srf only for my plugin.
But I cant get it to work.
I’ve tried Loft, Revolve Rail, NetworkSrf and couple of other things.
But I can’t get it smooth. Revolve Rail will make the corners “bumpy”.
All help is appreciated.

Here it is as one surface, although I don’t know where you want the seam…

Exactly what I was looking for. How did you make this?
For future usage

Basically you need to use MergeSrf with Smooth=No after having split a couple of the surfaces in the appropriate places (don’t forget to shrink the surfaces after splitting). Beware, this will create a “composite” surface with internal G1 joints. For some applications these may not be ideal.

Thanks for the video. It made a lot clear. Thanks

Just out of curiosity:
Why do you need it be one surface?
What’s the benefit in your case.

Nothing really special.
I got a plugin where I work with different brep’s that the user can edit to create an insole.
All the brep’s are defined by me. So if all brep’s are made out of 1 surface I can “use” all breps the same way and dont have to edit the code a lot 
Ah, I see.
Thanks, Norbert
