| P&ID |
| The application no longer crashes when using the SYNCHSTYLES command or saving changes in Project Setup for specific P&ID drawings. |
| Piping |
| AutoCAD Plant 3D no longer crashes when the number of ports is empty in Custom Parts Builder. |
General Update Content
The following defects have been fixed:
| Collaboration Workflow |
| Duplicated ortho relationships in the database do not occur in multi-user scenarios within collaboration projects. |
| Isometrics |
| Iso creation now succeeds when adding a pipe support to pipelines with small tolerance. |
| The Iso message box expands properly to accommodate the enclosed text in Iso annotations. |

| Unhandled exceptions no longer occur during Iso creation. |
| Orthographics |
| Centerlines are not offset after running the EXPORTLAYOUT command on ortho drawings. |

| Valve geometry is now fully visible in ortho views for specific projects. |
| P&ID |
| P&ID linetypes now remain consistent and do not change to continuous. |

| Revision clouds now display correctly in P&ID drawings after importing Excel files in Data Manager. |
| Piping |
| Bolt sets position correctly when flange wafer-type valves are placed without gaskets. |
| Project Management |
| Orphaned OPC data are now removed from Data Manager. |
