Projecting a marker onto a line
There are many cases in which it is convenient to project a marker onto a line. One particularly useful scenario is to project a marker placed laterally on the shoulder at the level of the humeral head onto a line passing vertically through a marker on the acromium.
To create the landmark, switch to Model Builder mode and click on Add a New Landmark.
