[Python][RhinoScriptSyntax] Questions:

Scripting

Question 1:
What is the difference between this:

and this:

NOTE: If they are different shouldn’t they be described differently in the api? It’s confusing.

Question 2:
am I wrong or there’s no method in RhinoScriptSyntax to select control points?

like rs.GetObject

NOTE: My idea is to extend the functionality of SetPt but I don’t know how to select the ControlPoints.

NOTE2: using rs.GetPoint and rs.GetSurfacePoint gives a point projected on the surface and not the control point you pick (cuz you’re not really picking anything you’re creating a point and its projection on the surface)

Yep, perhaps it does need a better description:

In the first, the points become the control points of the surface, in the second the surface passes through the points (like the difference between a control point curve and interpolated curve).

You will need to look at the ObjectGrip methods (‘grips’ category)

rs.GetObject does not allow you to select Control Points.

How would GripObject get it as it requires GUID and control points don’t have GUIDs?

I hope I’m wrong.

First, you have to turn them on:

https://developer.rhino3d.com/api/RhinoScriptSyntax/#grips-EnableObjectGrips

Then you can select them onscreen

https://developer.rhino3d.com/api/RhinoScriptSyntax/#grips-SelectObjectGrip
https://developer.rhino3d.com/api/RhinoScriptSyntax/#grips-SelectObjectGrips

You can find and move them without user interaction with

https://developer.rhino3d.com/api/RhinoScriptSyntax/#grips-ObjectGripLocations
https://developer.rhino3d.com/api/RhinoScriptSyntax/#grips-ObjectGripLocation

That’s about all I know, it’s rather unwieldy, but that’s what we have.
