When you select a drawing item on the Drawing Tree, the node for the item appears selected and the item is highlighted with the selection color in the graphics window. If the selected item is not visible on the current sheet, the item will temporarily appear highlighted with the selection color in the graphics window, and will become not visible again when the item in the drawing tree is unselected.

When you select an item in the graphics window, the Drawing Tree node for that item appears selected, if it is represented on the tree in the current task tab. If the item that you select is below a collapsed node of the Drawing Tree, the node does not expand.

When you select an item on the Drawing Tree or in the graphics window and the item belongs to the active drawing model, the corresponding model item appears selected on the active Model Tree. If the model item is below a collapsed node on the Model Tree, the node does not expand. However, if the active drawing model is not the owner of the selected drawing item, nothing is selected on the Model Tree.
