Entity Handle from DWG file in Viewer

By Adam Nagy

When you open a model in the Viewer that was created from a DWG file then you might want to be able to check the Handle value of the selected entity.

This is something that you can get from the object's properties through externalId:

As Jeremy mentioned it in the comments section, if the source seed CAD file is a Revit RVT model, the externalId will return the Revit element UniqueId property.

Similarly, if the source seed CAD file is a Revit RVT model, the externalId wil return the Revit element UniqueId property.
