Graphical Selection (Idle Mode)

In idle mode, entities can be selected from either the modeling window or the browser area. Selecting an entity in the modeling window automatically selects the corresponding entity in the browser and vice versa.

When working in a tool, entities should be selected from the modeling window.

Tip: In idle mode, convert your selection to a new entity type by changing the entity selector. For example, if you select elements, and then set the entity selector to nodes, all of the nodes associated with the selected elements will be selected.

Segments

Similar to element selection, segments can be selected graphically.
