14.4 Graphic machine model editor
This is how you create the machine model from the user interface in a graphic editor that has
2 areas:
● Tree view
In the "Tree" window, model the machine model based on the kinematic chain and allocated
protection areas.
● Graphic view
You also have the option of activating a graphic view.
In the "Graphic" window, you can view and check the result of the machine modeling in the
various views, and, for example, simultaneously correct in the tree view.
Elements that are selected in the tree are highlighted in color in the graphic view.
