Sir this is the file and i want you to take the variable offset surface of the top part of the piece like previously attached video

The previously attached first video is in rhino 5 and the second one is in rhino 8.I want the surface like rhino 5

Pls check the file ?

You are really not making it clear what it is, that you want…
When I extract the “upper” surface and untrim it I get this:

In Rhino 5 surface gets untrimmed:

In Rhino 8 it doesn’t:

If you want untrimmed result like Rhino 5, run _Untrim on the surface afterward.

Everytime i have to untrim it.is it possible to get directly without untrim, in rhino8?

You can with this Macro:
_VariableOffsetSrf _Pause _Multipause _Sellast _Enter _UntrimAll

Thank you sir.
