Worksession attached file can't find the object name

Dear Sir,
we try to separate our model to small one for easy management.And use worksession to import to one file.
but, we found we can’t find the object name in the file.
is there any solution?

hi Brian, From your description I cannot understand what the issue is, can you clarify?

sorry for my poor expression.
I use worksession to attache the external file.
but, i can’t use selname to select the object name.

Worksession is not designed for selecting objects inside attached files. To select files you will need to make the attached file active, then you can select the objects by name like in a normal Rhino session.
