Force direction

Hi~

i need Force direction
xyz?

attached file(BIKE3DMODEL, study : bike leg connection - pedalfootjoint - drawjointreactions- Forcemoment - F )
it can think pedal force??

i think
Red line - Anterior Posterior
Blue line - Medial Lateral
Green line - Vertical

if this is right
How do vertical direction division(Top and Bottom)

Hi,

The directions of reaction forces always follow the directions of the first reference frame of the joint.

So, you can add some code to see the directions of the first frame in the joint like this:

  AnySphericalJoint PedalFootJoint = {
    AnyRefNode &ref1= ....BikeModel.Crank.RPedal;
[b]    ref1 = 
    {
      AnyDrawRefFrame DrawFrameTest = 
      {
         ScaleXYZ = 0.1 *{1, 1, 1};
         RGB = {1, 0, 0};
      };
    };[/b]
    AnyRefNode &ref2 = ...ModelFolder.Right.Leg.Seg.Foot.ToeJoint;
    #include "<ANYBODY_PATH_TOOLBOX>/JointReactions/DrawJointReactions.any"
    AnyFolder &DrawRef=Main.DrawSettings;
  };

By adding some extra code, then you can see the direction of the first reference frame of the joint.

Best regards,
