### Add Three Presence/Absence Tools

Add two Presence/Absence Tools: one for each of the gasket's two smaller holes.

Set the following Presence/Absence Tool parameters:

- Adjust Threshold to look for light pixels.

- Adjust Limits so the tool fails when no hole is present.

Add a third Presence/Absence Tool to measure the size of the gasket's center hole.

- Adjust Threshold to look for light pixels.
