Form: Tendon Local Axis
The program automatically determines the local axis for tendons from their connectivity and orientation. The Assign > Tendon > Local Axis command can be used to modify these axes when necessary.
Select one or more tendons to be assigned a modified local axes.
Click the Assign menu > Tendon > Local Axes command to access the Tendon Local Axis form.
Type a value in the Angle in Degrees edit box. This is an angle by which local axis 2 of the object will be rotated around the local axis 1. Local axis 1 is along the length of the object. By default local axis 2 is always in the 1-Z plane, except if the object is vertical and then it is parallel to the global X axis. The definition of the local axes follows the right-hand rule. The angle is measured counter-clockwise as positive if the local axis 1 is pointing towards you.
Note: By default global Z is taken as the 3D View Up Direction. If needed, change the UP direction for the display using the Options menu > 3D View Up Direction command. If the UP direction is changed, it will only affect the display of the model and does not affect the local axes definition in any way.
