Trimble Access 2015.21 was released over the weekend to fix a few bugs that were found in 2015.20. If you currently have 2015.20 installed, it is recommended that you update. Below are the three main bug fixes, and a link to the release notes for more information.
Polylines in DXF files: An issue where DXF files with polylines in feet had incorrect positions for starting points of the polylines is now resolved. This issue was introduced in Trimble Access version 2015.20.
Area calculations: An issue where Trimble Access would occasionally calculate significantly inaccurate area results is now resolved.
Application error: An issue where setting up an RTK base on a position that has been derived from a GNSS survey such as VRS or RTK would cause an application error when attempting to store the first point in the job is now resolved.
