I have an older file that I need to update the features in-field. It is no longer available as a SSF. Im using Trimble positions and ARCMap with a Trimble GEO XH. I have posed this question before, but have not found an answer that works. I am unable to bring the feature class into the Positions checkout dock window to transfer it to the GEO as a SSF. Am I missing a step, or doing something wrong? Its quite a large file and I would hate to start over (2500+ points). Is there another way with Trimble software or other to revert this back?
