I found that these cannot be strongly constrained. Unable to achieve precise surfaces.

I have found that "Grid Surface" can achieve precise surfaces, so can we use this in turn to generate surfaces from countless points. Just like the effects of the minics below. Because it would be much more convenient to operate in this way。

You can allow concavities in the surface by decreasing the "Convexity" parameter. You can also control the surface better if you place the control points on the surface more uniformly. You might also realize that the desired "precise surface" is actually impossible to accurately achieve in a surgery.

There are many other options, for example:

• Grid surface markup (provided by SurfaceMarkup extension) as you have noted
• Baffle Planner module (in SlicerHeart extension)
• Scissors effect from a few viewpoints

I have tried all the options below, including "Convexity", "Control the surface better if you place the control points on the surface more uniformly", and so on. But indeed, I still cannot meet the precise surface requirements I require. I definitely urgently need a precise surface. May I ask if you can provide a modification idea for the SlicerMarkups ToModel source code to meet my precise surface requirements? Thank you.
