The elements involved are:LaborThe element that moves around the system, meeting process Requirements, or loading and unloading parts at various locations. Labor controllerThe controlling element that controls the behavior of the various labor in the model.Labor decision pointsThese are loading and unloading points where labor can stop, pickup and drop off parts on path systems. Labor path systemThis represents the layout on which the labor can move and where labor decision points are located.Labor pointsThese determine where labor stand when at an element. Labor via pathsThese define the path labor takes between elements that are not connected by a labor path system.The first step in the creation of a labor system is to define a controller. If a labor path system is required, the next step is to use buttons below the Model | Layout | Create System title bar to define the attributes of the labor path system, such as speed of travel and the cross section to extrude to form the display of the segments. The Layout and Segment buttons are then used to create segments, and join them together. The Model | Layout page is provided so that path systems may be created by defining a series of curves and lines, thus avoiding the tedium of creating each path segment as a separate CAD part. A cross section is extruded along each curve and line to form each path segment. A more detailed discussion of the layout page can be found in Chapter 8, Layout. Once a path has been created you add decision points for load and unload points. You can use the built in or custom popups to define the behavior of the system. NOTE: Paths do not need to be defined for a labor system to operate. If a path is not available, the model will automatically create a via path for the labor to move along. This is known as auto path generation in QUEST. In this chapter it is assumed that you are now familiar with the basics of the QUEST user interface and with the concepts of elements, classes, and parts.Objectives This chapter describes the concepts and characteristics of a labor system and the buttons that are used to create them. Each button is described and the details of its parameters discussed. An explanation of how these parameters may be used to model physical systems is provided. Associated Tutorials This chapter contains explanations for many of the concepts presented in the following chapters of the QUEST Tutorials.Chapter 11, Labor I Chapter 12, Labor II Chapter 13, Labor III Chapter 17, AGV Modeling IIIIt is advisable that you work through these tutorials in conjunction with reading this chapter to gain a better understanding of how to use labor systems. Common Labor System Creation Topics Naming Conventions When a new path system, labor, or decision point is created a new element class is created. QUEST automatically assigns unique names to the class and all the segments/elements in that class. The class name will be the type of the element class followed by a number, ., Labor1 is the first element class of type Labor created using the default options. You have the option of entering a custom class name. The segments or elements in that class will then be named with the class name followed by a number, ., Labor1_1 will be the first labor element of class Labor1. The individual element names cannot be set when the element class is created, but once created, can be renamed by selecting Model | Build | Element | Modify. If the name of an element class is modified at some stage after it has been created, then QUEST will present you with the option of automatically renaming all the elements in that class. Element Geometry The following buttons allow you to set the display parameters of the element such as geometry and color. Color This button is used to assign color data to the element class. You select a color from a pull down list of the available system colors. NOTE: If you created the part in the CAD world, then the sub objects of the part that will be changed by this button are those that were created with the color part user defined in the CAD world. 3D File This button is used to set the geometry for an element class. There are two alternatives:Default GeometryThe new element will b
