Hi Joe,

let's see,

---

• it looks like the first one is a string (a piece of text), that contains a representation of a Guid
• the second one is an instance of a Guid
• the third is a geometry object

---

RhinoCommon instances are objects that represents geometry models. When they are added to a document, a Guid uniquely identifies them.

You can read more if you click on the GhPython component, and choose Help.

The rhinoscriptsyntax module has a few rs.coerceXYZ() functions to get objects from Guid, and scriptcontext.doc.Object.AddXYZ() can be used to add data types to the document and get a Guid.

great, I've been using coerce commands with a bit of success. However, scriptcontext.doc.Object.AddXYZ() I have not known about.. Is there a directory for RhinoCommon like there is for RhinoScriptSyntax? I've seen many discussions around Rhino Common, but no tutorials or briefs on what it is or how to use it. Does it not work with Python? If there is a link to some page for help, I would greatly appreciate you pointing me to it.

Thanks a lot

Also, if you have not already, please read the GhPython help within Grasshopper and tell me what it is missing :) Thanks!
