Hi YJ,

 

you cannot pick Grasshopper points in Rhino. They don't exist as far as Rhino is concerned.

 

What you can do is reference an existing Rhino point object. When you go to specify a point in the Point Parameter dropdown menu (Set One Points or Set Multiple Points) there's a Type property. Change this into Type=Point and you can select Rhino points. Whenever you drag these Rhino points about, it will update the Grasshopper solution.

Thanks, David,

Could I have a chance to know how this is possible?

You'd have to ask Daniel how it's done, but I don't see anything out of the ordinary here. He probably referenced some Rhino point objects, then used those to control Kangaroo inputs.

 

He's doing it in Rhino5 since he's got the gumball modifiers.

Oh, sorry, I thought he was picking the point on mesh while it is deforming, but I just realised it is pre-refered at beginning as restrained points.
