picking-por-medio-de-una-lista.fsm I have the following model where the boxes that enter the shelf represent boxes with material, a box can have between 1 to 30 units inside. When picking I want the operator to only take the units inside the boxes (as if it were a separator) but when the last piece takes the piece and the box to leave the product in its respective place and the box disappears in a sink. Can this be done, and if so how is it done? I would appreciate your help.
