Located in the bottom-right corner of the screen are four performance indicators that give you feedback on the performance of your computer and currently loaded Navisworks model (Figure 1.28).
FIGURE 1.28 Status bar indicator
Pencil Bar Indicates how much of the current view is drawn. That is how much image “drop-out” there is in the current view. When the progress bar is at 100%, the scene is completely drawn, with no “drop-out.” The icon changes color when a redraw is in progress. While the scene is being drawn, the pencil will change to yellow. If there is too much data to handle and your computer cannot process this quickly enough for Navisworks, then the pencil changes to red, indicating a potential problem.
