Summary:
Ligament class does not scale its attachment points

Detailed description
Hi

I've included an Anterior Cruciate Ligament in my model using the new Ligament class. I've manually (i.e. by inspection on the GUI) found the Pathpoint set for the ligament, which is as follows:

<PathPointSet name="">
<objects>
<PathPoint name="ACL_a-P1">
<location> -0.008 -0.405 0.008</location>
<body>femur_r</body>
</PathPoint>
<PathPoint name="ACL_a-P2">
<location> 0.02 -0.035 -0.007</location>
<body>tibia_r</body>
</PathPoint>
</objects>
<groups/>
</PathPointSet>

However, when I scale the model, these insertion points are not scaled accordingly (as they would if it was a muscle).

In addition, it would be great to be able to view the change in length of the ligament during a motion task (as you can with the MuscleAnalysis tool).

Kind Regards,
