Before uninstalling the former version, please make a copy of the complete folder  Drive:\Program Files\Bentley\ProStructures CONNECT for AutoCAD\AutoCAD 2019 or -20. or use the archiving assistant.

ACIS bodies may cause crashes, and elements within the ACIS/solid modeler can lead to crashes when creating views. If object lines are missing in generated drawings, it is necessary to execute the command Ps_rebuild: 10, best before creating any drawing. Additionally, if boolean operations have been performed, they should be checked for presence. It is recommended to avoid using the ACIS option in NC data export and DXF due to known issues. Don´t use in the detail styles the setting "Plates as Acis".
