Audience: Supervisor

This lesson uses a fictional frame and a person with only the supervisor role. No result here is approved for real manufacture.

## Handle an invalid dimension

1. **Configurations**

   Configurations.

   Open configurations.

2. **Choose the training frame**

   Choose the training frame.

   Use an already approved and active release. Each configuration describes exactly one unit.

3. **Enter the frame width**

   Enter the frame width.

   Enter an exact width of 800 millimetres. Check the selected unit alongside the value.

4. **Enter the frame height**

   Enter the frame height.

   Enter an exact height of 1000 millimetres.

5. **Choose the finish**

   Choose the finish.

   Choose the approved natural finish from the declared options.

6. **Choose whether a panel is required**

   Choose whether a panel is required.

   Choose no panel for this frame. Do not infer a missing option.

7. **Enter an out-of-range width**

   Enter an out-of-range width.

   This fictional width is below the declared minimum. Evaluate it to see the refusal, rather than guessing a replacement.

8. **Read the invalid result**

   Read the invalid result.

   The evaluator refuses these inputs. Correct the source values and evaluate again; do not accept or manufacture from an invalid preview.

Check the current record and your own authority before working with real data. An evaluation result never authorises manufacture.
