Ask AerTwin what something means

AerTwin explains itself. Nothing is pressed or changed while Explain is on, so it is safe to use in the middle of any task.

To explain anything on the screen

1. On the toolbar, click Explain.

   A card asks you to select anything on the screen.

2. Click the button, figure, pin, label or panel you want to understand.

   The card says what it is and, where it helps, when to use it and what to do next. Some cards add a Technical basis section, and some offer See diagrams.

3. To go through everything on the screen in turn, click Next and Previous on the card, or press Tab.

4. Click Done, or press Esc, to go back to work.

To explain the figures of a measurement

1. In the Measurement panel header, click Explain.

   A plain-language sentence appears under every figure, with notes on how the figure was obtained. The figures themselves do not change.

2. Click Explain again to hide the sentences.

To compare the ways a volume can be measured

1. Select a volume, a 3D defect or a depth profile.

2. In the Measurement panel, click ? beside the volume, or What do these figures mean? under the figures.

   Illustrated cards compare the base surfaces, the 3D defect reference and the depth profile.
