Hi Philip- Rhino.ObjectGroups() in RhinoScript, Also implemented in Python/Rhinoscript Syntax. Does that help you?

Hello,

ObjectGroups(obj) will return all the groups that the object is a part of (as one object can be a member of several groups)

ObjectTopGroup(obj) will find the top-level group that an object is in (as one object can be in nested groups). This is apparent not yet implemented in Python, so it’s only in vb Rhinoscript.

ObjectsByGroup(group) will return all the objects in a particular group.

Thanks! I have overlooked that.

Hi Pascal,

You mention it’s also implemented in Python but when I try it out it doesn’t seem to work for me? In this script:

import Rhino

grouplist = []
for x in objcts:
group = Rhino.ObjectGroups(x)
grouplist.append(group)

I get an error saying “Message: attribute ‘ObjectGroups’ of ‘namespace#’ object is read-only”

Any idea?

I found it.
I used rs.ObjectGroups(x)
