Connections
Ports, nominal size and connection diameter
Define where a component connects, which way its ports point and the physical connection dimensions required by the selected standard.
- Where to find it
- Designer Port Tools; Export component connection metadata
- When to use it
- Making exported components connect correctly

Step by step
- Add or move the required ports with snaps or numeric positions.
- Confirm every port direction against the intended connection.
- Provide or bind the actual nominal and outside-diameter values for each port.
- Review automatic values and enter explicit supported overrides where data is unresolved.
- Export and connect pipe to each port in a test drawing; check position, orientation and diameter.
DN is not OD
A nominal designation does not determine physical outside diameter without a standard. A flange bounding diameter is not a pipe OD. Port coordinates also do not establish OD.
Automatic values
Available explicit port metadata, scoped owner bindings, size-table outputs or unambiguous supported cylinder-cap geometry can supply values. Review the result; unsupported or conflicting geometry must not silently generate an invented diameter.
Reducers and copying
Check the two ends independently. Copy OD to matching checked sizes applies only to appropriate known matching DN/port names; it does not populate every size or infer standards.
Units
The documented export connection-grid OD is in mm even when project display uses inches. Follow field labels. Native output converts physical dimensions at its boundary; nominal size remains a designation.
Keep in mind
- Validate both ports after movement, rotation, size changes and unit changes.
