Parameters

Eval

Member	Value	Description
eMtoTrackEvalAll	0	Returns 1 if every track is within range otherwise it returns 0.
eMtoTrackEvalAny	1	Returns 1 if any track is in range of the Object, (ie, lowerLimit <= range <= upperLimit) else returns 0.

TrackIds

Time

Example

Determine if all the specified tracks (i.e. a subset of the MTO tracks) are visible from the other STK Object at the specified time?
