I'm lost. I just trashed a drawing to test it and I can pick convert the lowest number, edit attach, and continue no problem. You only want to be picking the non 0 number, so try picking the second smallest number. If you do get the pick worked out, make sure when it asks for the baseline you pick the baseline side of the dim you just edited. I'm using WF3 m110 if that might matter.
Thanks
