Node object represents the member or surface end joints or supports in finite element analysis.
In OpenBrIM, a Node object supports six degrees of freedom (DOFs): translation X, Y and Z; and rotation X, Y and Z.
Support view can be toggled on/off from settings menu. Settings can be reached by clicking the gear icon in lower left corner.
Based on the way structural components are positioned in 3D space, it is possible to have nodes at the same location (ex. top of one component is at the same location as the bottom of another component sitting on top). In the case of OpenBrIM app, the nodes will automatically be merged before going into analysis phase.
