Validation is one of the most powerful features of AutoCAD Plant 3D. This feature ensures that all piping and instrumentation diagrams are accurate and comply with industry standards. By automatically checking for errors and inconsistencies, it helps prevent costly mistakes and rework.
The validation feature identified several potential issues early in the design phase:
- Base AutoCAD Object - An AutoCAD object or block (instead of an AutoCAD P&ID component) has been inserted in the drawing. Such blocks do not show up in reports or in the Data Manager, even though they may look like a P&ID component.
- Size mismatch - The size of a line and its associated component do not match. This condition is usually caused by manual changes to the component properties.
- Spec mismatch - The specification properties (details such as the component material) for lines and inline components do not match. This condition is usually caused by manual changes to the properties.
- Non-terminating line - Process lines do not terminate through a connection to an endline component, or do not end with an endline symbol signifying an air vent, water outline, drain, or other valid terminator.
- Unconnected Component - No true connection exists for lines and their associated components, even though they appear to be connected. This error may result if a proper connection was never established, or if a component was dragged away from a line.
- Flow Direction Conflict - The flow direction is incorrect for a line or component.
- Orphaned Annotation - An annotation tag has been moved away from the component with which it is associated.
- Unresolved Off-page Connectors - Off-page connectors used to connect the current drawing with another drawing do not specify a valid project location.
This helps save the company significant time and resources.
I'm excited to see how AutoCAD IST and its P&ID validation feature will continue to shape the future of design and engineering.
