Get and Set Sensor Example (VBA)

This example shows how to get a Measurement (dimension) sensor, resets its value to set off an alert, and fire notifications before resetting value.

Module

'---------------------------------------------------

' Preconditions:

' 1. Open a part document that has a dimension

'    of 2.5 inches and a corresponding Measurement

'    (dimension) sensor that has an alert set to

'    go off if the value of the dimension is

'    reset to > 3 inches.

' 2. Select the Measurement (dimension) sensor

'    of 2.5 inches in the Sensors folder in the

'    FeatureManager design tree.

' 3. Click the Run Sub/UserForm button on the

'    toolbar in the IDE.

' 4. Click Run.

'

' Postconditions:

' 1. The Measurement (dimension) sensor alert

'    is enabled, if it wasn't previously enabled.

' 2. The value of the dimension is set to 3.5

'    inches.

' 3. The Measurement (dimension) sensor alert

'    is triggered and an event is fired

'    whenever the sensor is updated.
