Working between RhinoCommon and python RhinoScriptSyntax

[NavArch]

Hi,

So I've had to write some code that uses RhinoCommon and python RhinoScript. My question is how do I get the two to work together?

I get that rs.coercecurve() for example, will use a curve's GUID to get its RhinoDoc info.

What I can't figure out is how to go the other way. Say I have a Brep, How do I get it's GUID?

I'm sure there is a simple answer but I haven't been able to find it

Thanks
Ian

Hi Ian,

if you want to get a Rhino Common Object from a GUID, take a look at this post.
http://python.rhino3d.com/threads/22...ct-from-a-Guid

Genereally a Brep object is totally virtual and does not exist in the Rhino Document before you specifically add it to the document. Before it is added to the document it does not have a guid.
(Just like a Grasshopper Object, which doesn't exist before it is "baked")

So you cannot retrieve a guid from a "virtual" object. The only way to retrieve a guid is by adding the object to the document.

I hope that helps.

Hi Ian,

here's an example code:

python Code:

import rhinoscriptsyntax as rs
import Rhino
import scriptcontext
 
def TestScript():
   
    #Create the Object   
    PointObject = Rhino.Geometry.Point3d(3.3, 4.98, 5.35)
   
    #Get the Document
    doc = scriptcontext.doc
   
    #Add the PointObject to the Document
    guid = doc.Objects.AddPoint(PointObject)
 
 
# call function defined above
# Here we check to see if this file is being executed as the "main" python
# script instead of being used as a module by some other python script
# This allows us to use the module which ever way we want.
if( __name__ == '__main__' ):
    TestScript()

Thanks Martin,
The sample code made everything clear.
