Refresh Navis Data Stamps¶

Checks every Fabrication part and connected native element in the model, and makes sure the parameters that Navisworks relies on are correct. It also keeps the Style keys on native elements in step with their Fabrication service, and reports anything that needs your attention.

Why it's needed¶

When a Revit model is opened in Navisworks, all Fabrication insulation ends up in one category, and native elements such as grilles, valves and flex duct don't carry a Fabrication service at all. That makes it hard to build search sets and clash tests by service.

To fix this, Integra add-ins "stamp" each element with its service:

These are kept up to date automatically in the background as you work. Refresh Navis Data Stamps runs the same checks across the whole model in one go.

When to run it¶

• Before exporting to Navisworks, so search sets and clash tests pick up every element.
• After opening an older model, or one that's been edited by someone without the Integra add-ins.
• After large changes, such as swapping services or reworking a run.
• To find elements that need a Style picking.

Step by step¶

1. On the Integra Tools tab, in the Fabrication Tools panel, click Refresh Navis Data Stamps.
2. Wait while it checks the model. On a large model this can take a little while.
3. Read the summary (see below), then click Close.

The whole run is a single undo step.

Reading the summary¶

The summary is long, so it's explained here one section at a time. Any element listed is shown with its ID, for Manage → Select by ID. Each list shows the first 10 elements and how many more there are.

Fabrication Statistics¶

Every Fabrication part has been checked and stamped:

• Externally insulated: the part has insulation, so its service is written to Navis_Insulation_Service.
• Internally lined: the part has a lining, so its service is written to Navis_Liner_Service.
• Uninsulated: no insulation or lining, so the insulation fields are cleared and Navis_Is_Insulated is set to No.

Hybrid Family Statistics¶

Native elements (families, native duct and pipe, flex duct) are traced back through whatever they're connected to, up to six elements away, to find the nearest Fabrication part. Equipment, such as fan coil units, is never stamped and is never traced through.

• Stamped/Verified: the element's Navis_Hybrid_Service matches the connected Fabrication service.
• Cleared: the element is no longer connected to Fabrication, so its old service has been removed.
• Connections repaired (family touching Fabrication but not connected): a family was sitting against an open Fabrication end (within 10 mm) but wasn't actually connected. It's now connected, then stamped.

Service Filter (Style keys)¶

This is the same Style key sync described in RVTFC: What's kept up to date for you.

• Updated to match their service: the service part of the element's Style was changed to match its Fabrication run.
• Already correct: nothing needed changing.
• Service-independent item, left as picked: rows such as Expansion Vessel, which don't depend on the service.

Two lists need action:

Orphaned elements¶

Orphaned elements are native elements that aren't connected to any Fabrication run, so they can't be given a Navis service. In Navisworks they won't appear in service search sets or clash tests.

• If the element should be connected, such as a grille with no flex, connect it. Auto-Flexi Duct can do this for ductwork.
• If it's meant to stand alone, it can be ignored.

If everything is connected, the summary ends with a success message instead.
