• The exporttoautocad command breaks acquisition rules.

Data Properties

• Plant data in project drawings occasionally does not save properly. Data loss can occur when working with custom classes, if a drawing is removed and added again, or when modifying referenced (XREF) drawings.

Fixes that apply to AutoCAD Plant 3D only:

3D Model

• Modifying staircase step data occasionally causes the program to shut down unexpectedly.
• If a block that contains piping is inserted into a non-project drawing, a recovery error message displays when the non-project drawing is opened.
• Exported SDNF files do not reflect recent edits.

Isometric Drawings

• Coordinates added to end connections (CONT'D ON) do not display in the isometric drawing.

Spec Editor

• The Spec editor requires Admin rights to modify a piping spec or catalog.
  
  Note: With this hotfix applied, you are not required to have admin rights to modify a piping spec or catalog. However, other Spec Editor features do require that you run the Spec Editor with admin rights (using Run as administrator). For example, admin rights are required to modify the shared content folder or to edit description styles.
