Hi everyone,
I need to model a surface as accurately as possible based on a specific boundary and several spot elevations (survey points).
The boundary is non-rectilinear, and the heights vary across the site. I’m looking for the best workflow to ensure the surface passes precisely through these points without the “bubbling” effect often caused by a loose patch.
Could you please share the basic 3dm file?

yes, thank you.
Please give it a try with Patch, and fyi.

Hello,
If you want precision : use a mesh that connects each points (delauney is usually a good one for that kind of tasks)
If you want good looking a relative accuracy : use patch
To my knowledge that is the choice you have to make.
It looks like you need more spot heights outside of your boundary to get an accurate result inside it. You can cheat it by copying the ones you have a couple of times, but at the moment each point is probably too weighted, and the patch won’t go past your boundary curve (I’m assuming you don’t want the planar boundary to influence the patch geometry here).
I’ve attached how I’ve handled it in the past, but ideally you would have the other spot heights
