There are three ways to change Constants and Lookups interactively:
| 1. | Click on the Set up a Simulation button, then click on a Constant or Lookup appearing highlighted in the sketch. |
| 2. | Click on the Set up a Simulation button, then click on the Constants  button or the Lookup  button on the Simulation Toolbar. |
| 3. | Open the Simulation Control, click on the Changes tab, then click on the buttons Change Constants… or Change Lookups… |
If you have specified any changes files in the Simulation Control dialog these will be read before interactive changes are made. This is true whether you are making interactive changes from the Sketch or from the Simulation Control dialog.
