Install the Autodesk Civil 3D 2020.5.1 Update prior to installing the Autodesk Civil 3D 2020.5.2 Update
Autodesk Civil 3D 2020.5.1 Update includes the product fixes included in Autodesk Civil 3D 2020.1, Autodesk Civil 3D 2020.2, Autodesk Civil 3D 2020.3, Autodesk Civil 3D 2020.4 and the previous Autodesk Civil 3D 2020.5 Updates.
Autodesk Civil 3D 2020.5.2 Update
Autodesk Civil 3D 2020.5.2 Update addresses issues with Feature Lines that are used as Corridor Baselines.
When Feature Lines in a site were used as Corridor Baselines, Feature Lines would unexpectedly disappear from the Site.
In addition, unnecessary hidden Alignments were created when a Baseline Feature Line was updated.
This update prevents Feature Lines from disappearing from Sites, and prevents the hidden Alignments from being created in a Site.
The Civil 3D 2020.5.2 Updates includes a new PurgeHiddenAlignsFromSites Civil 3D command that will purge hidden Alignments in Sites from existing drawings.
After running the PurgeHiddenAlignsFromSites command, the Corridor will be out of date.
This is because when a problematic Alignment is purged, a new Alignment will be created for the Corridor and the Corridor will need to be rebuilt.
The new command does not restore missing Feature Lines to Sites from which they disappeared.
