Answer:
The model check allows you to find members that cross each other but do not have a common node at the point of intersection (see Image 01). You can open the model check using the menu Tools → Model Check → Crossing Unconnected Members.
The result is shown in the "Groups of Crossing Unconnected Members" section. The crossing members are listed in groups; the current group is indicated by an arrow in the graphic.
The "What is to happen with" section controls how the crossing members are handled. The "Connect members" option is suitable for actual transfer options of internal forces, but not for general diagonal crossings with tension members, for example.
As an alternative, it is also possible to use the model check to display the member pairs as an Excel list or to create visibilities. The visibilities created in this way can be quickly used to find and delete relevant members in the model. The video shows how crossing, unconnected members are displayed without tension members, then connected.
