Hiding Components

You can use rollbars to temporarily hide components, to help you focus on a subset of components.

1. Under the column headers, drag the horizontal bar down and position it below gear-caddy.
   
   
   
   In the graphics area, the heaviest component, gear-caddy, is hidden.
   
   
2. At the bottom of the list, drag the horizontal bar up and position it above shaft gear insert.
   
   
   
   The three components that weigh the least are hidden. The spectrum adjusts to the visible components, showing their relative values.
   
   
3. Return the bars to their original positions:
   1. Right-click the top bar and click Roll to Top.
   2. Right-click the bottom bar and click Roll to End.
