I have a bunch of curves. I create 4 edge surface of them. What I trying to create is on the sketch. Since I have no idea how to do that, I am trying BrepOffset to achive the desired geometry.
Unfortunately The solution sometimes works sometime does not. I have no idea what is the problem because the four curves groups are just slightly different. Any idea what is the problem?
Any idea how to achieve the desired geometry differently?

there are surface extension components in plugins like Wombat, it looks like working well on your initial curves

I believe you can also script surface extension

This solution does not work. If you take a look on the sketch the suface is extended in XY direction not just Z.
Thank you! Unfortunately Wombat is an addon which was updated 4 years long ago. There is no support for 7 and 8. I afraid using that, because I like my solution have at least a bit of guaranty that it will work.

I think that component just embeds this RhinoCommon method: https://developer.rhino3d.com/api/rhinocommon/rhino.geometry.surface/extend?version=8.x
you can find snippets coded by users in the forum like this:
here is that C# script applied to your original surfaces, it produces extended surfaces with very same area of Wombat component, but is not plugin dependant
