In the case of fiber glass reinforcement, user has 2 options to define the geometry, Wizard and Define. For a quick layout, one can use the Wizard, that will automatically create the circles at the interior of the area created by the theoretical excavation shape. If the result is not the one intended, the user can use the Reset option and then input new values. If modifications are needed, one can enter the 2d sketcher mode by using the Define option and manually add/remove elements.
