If you for example want to carry out a resection and afterwards a transposition of a muscle, you would first simulate the resection in the form of a change of the parameters "Tendon Length" and respectively "Muscle Length (L0)" in the force model and afterwards carry out the surgery "Transpostition" interactively in the 3D-view. However, a resection as well as a plication can also be carried out via the "Non-Graphical Surgery" dialog. In this case, the system automatically applies the resection or the plication on the tendon length and muscle length (L0) parameter in the background.

If it is necessary to define the new location of an insertion point via marking off from the points of reference, you can use the methods "Measure" and "Triangulation". Of course a non-graphical transposition of a muscle insertion is also possible.
