Update geometry automatically when changes occur, and minimize time-consuming manual redrawing. Define simple foreground and background selections that redraw geometry to show hidden or dashed lines of parts obstructed by other parts in your design. Identical parts can have different geometrical appearances when hidden. AutoCAD Mechanical recognizes that they are still identical if you need to change the design or get an accurate count for the parts list.
