By default BimSens data and the 3D viewer are Not Connected, and selecting objects in one will not trigger any reaction in the other. To connect the 3D to the data you must define an ID Match.
An ID Match It is a set of rules, each rule comparing a Property (or column) of the DataView with a Property of the 3D object or viewpoint. Items of the DataView and 3D objects are considered equivalent if the values of the 2 Properties match.
