Is there an elegant way to map a Point grid on a closed SubD surface?

[Wiley]

If you could see my poor drawing, I would like to have a Point grid mapped on a closed SubD surface. Something that resembles the panelling tool.
I tried it with panelling tool plugin but it fails to work with closed surface.

I am guessing there is no easy way to go about it?

Wiley,

I found two ways that might work for your purposes. First, this simply uses the grid from the form of the SubD. Convert to mesh, extract SubD vertices, and use mesh closest point to bring the points to the SubD. This method will require you to control the subdivisions of the SubD.

Second may give you a little more control. Feed SubD into Brep component, deconstruct Brep, divide faces of the Brep by their UV to add a point grid to each face. It creates a really nice grid but may require some back and forth between the SubD and the Surface divide component to calibrate the grid.

There may be additional tools out there too but this was some quick solutions that might work for your purposes.

I feel like a fool asking this.
But I don’t see anywhere inside grasshopper that allows me to extract the vertices of SubD?

Not at all! It looks like you might need to update your rhino/grasshopper maybe? You seem to be missing some SubD components. An alternative to this could be to grab the SubD control points which should map to the mesh similarly.
