Hi Olivier I had a similar problem once, which I solved by converting the input out of a list to a string:
Your command: select_obj.append(Selection(selection[i])) Change it to: select_obj.append(Selection(str(selection[i]))) --> change selection[i] to str(selection[i]) Python sometimes reads string entries from a list as u'stringofentry'. Hope this helps Cheers Michael Olivier Serve schrieb: > Dear Edward, > Thank you for answering so quickly. I will send you all details > tomorrow (It is night time for me now).
