Get points from Rhino

Hi all!

Is there a way to retrieve a point from Rhino in a vbscript component?
I would like to use its name or its ID to do that. How can I do?
I tried to use the object iterator but I don't know how to convert MRhinoObjects to On3DPoints.

Thanks

The best thing to do is to use the LookUpObject method, then use an mRhinoObjRef to get to the point. If you happen to get the mRhinoObject from the object iterator, that's fine too. See below



Dim rhObj As MRhinoObject = doc.LookupObject _

(New guid("CA0BC96F-64F3-4411-8D6E-37C094CBD629")) 'replace with your guid

Dim rhObjRef As New MRhinoObjRef(rhObj)



If rhobjRef.m_geometry_type = IRhinoObject.GEOMETRY_TYPE.point_object Then

Dim my3dPt As On3dPoint = rhObjRef.Point.point

Print(my3dPt.x & "," & my3dPt.y & "," & my3dPt.z)

End If

Thanks Damien, it works !

I have another question, can I get UserData from the point?
One more ! Can I use the name of the point instead of the Id?

Many Thanks

When it rains it pours... I'm the last person you want to ask about user data. I'm battling that fight now, so if I make it out alive I'll see if I can help.

The name of the point itself is not likely to be truly reliable (since there could be multiple objects with that name), but if you like you can use it. The only way I know of retrieving the objects by name would be through the object iterator.

Thanks to you : http://www.grasshopper3d.com/video/first-attempt

I'm going to find a solution for the UserData...I'll let you know if I get one.
