Thanks. Looks like it is only an SR2 bug so far.


Yes, exactly. No problem with previous release.

I noticed this behavior in rhino5 when I use rhinoscriptsyntax to copy or translate objects in a group. They always end up in the same group. I don’t know if this is normal or not.

import rhinoscriptsyntax as rs
objs = rs.GetObjects("select a group of objects:")
rs.CopyObjects(objs, [0,0,3000]) #the copy will become part of the group

Hi Bogdan - Yeah… I think this is probably at least ok in scripting - you have the control in the script to handle it.

import rhinoscriptsyntax as rs
objs = rs.GetObjects("select a group of objects:")
x = rs.CopyObjects(objs, [0,0,3000])
for id in x:
y = rs.AddGroup()

The bug in 6.2 appears to be that all added groups are called the same thing, which makes them all one group. In the script, whatever group memberships the objects have are kept on copying. That might or might not be the right thing to do but as far as I can see it is a different problem…


Same problem here latest release candidate, making 1 group , and then making another grouip makes it 1 group, not handy

That’s what this topic is about, RC (6.2.18038.4101, 07/02/2018) problem.

Thanks @pascal

The problem complicates easily if, for example, I have several groups and need the copies as several other groups, or even worse, if I have groups inside groups.

This bug is not smashed in (6.2.18043.22301, 12/02/2018) and it’s annoying. :roll_eyes:


Hi All - this was fixed yesterday - the next 6.2 RC should have the fix.
