I can’t seem to rebuild these surfaces to be able to edit their edges (or using SolidPtOn). Sample 3dm attached.
I tried rebuilding them with similar results (Rebuild set to U1 V1 Degree 2 and Reparametrize U and V from 0 to 1 and ShrinkTrimmedSrf).

These are some of the problematic control points:
The points aren’t in one line so the command Simplify lines and arcs doesn’t help.
I think the quickest solution is to duplicate the borders and manually delete the control points which aren’t really needed, then create new surfaces with the boundary curves.
That makes sense, thank you for the explanation and for showing a practical solution.
Thanks
Also keep in mind the surfaces are far from the origin, which might cause problems too…
You could also do this in Grasshopper:

Don’t ask me why such a high tolerance is required to get rid of all “unneeded” control points?
Wow, thanks a lot - much more than I initially bargained for. I need to check quickly how to use GhPlayer - I think that it will be useful to turn this into a separate Rhino command.
The reason it’s so far from origin is because we’re modelling a masterplan in millimeters. Originally it was even further (“geolocated”). I may not be able to move it closer, but hopefully the above script will still manage to work in this scale.
