«Bottom-Up» Design The following description relates to the first two techniques of inserting a fragment into a drawing. The third technique is described in the dedicated section “«Top-Down» Design”. Enter the command “FR:Create Fragment” for inserting a fragment into an assembly drawing: Keyboard Textual Menu Icon “Draw|Fragment” The following options will appear in the automenu: Select File Create new Fragment in Assembly Context Extract Fragment Drawing Set Fragment parameters Repeat previous Fragment (accessible upon a repeated call to the command) Select Fragment to create its copy Execute Edit Fragment command Exit command The controls for customizing parameters of the fragment will appear in the properties window. They are put into several sections, their number and structure depend on the fragment creation approach. The sections of the properties window allow selecting the file of the fragment being inserted, a way of attaching the fragment, specifying external variables of the fragment, etc. Before selecting the fragment file the dialog in the properties window contains only three sections: “Basic parameters”, “Fragment parameters”, “Options”. The values of the parameters, defined in the properties window before file selection, are automatically stored as default values for all subsequently inserted fragments. The first step when inserting the fragment is the selection of the file of a fragment. The dialog window for selecting a file can be called with the help of the option or by pressing the button in the section “Basic parameters” of the command's properties window. In the window for file selection it is necessary to indicate the document file of the fragment. After selecting the file, a dynamic image of the inserted fragment attached to the cursor will appear in the drawing window. The contents of the automenu will be changed. The new state of the automenu will depend on the fragment attachment approach specified in the properties window: by fixing points or by fixing vector. The fragment attachment approach is specified in the section “Insert Fragment”, with the help of the parameter “Fixing”. In case the fragment is attached by the fixing vector, the required fixing vector can be chosen from the drop down list of this parameter. The required page of the fragment document can be selected here as well (in case of multi-page document). In the section “Fragment parameters” of the command dialog it is possible to specify various settings for fragment insertion. A detailed description of these parameters is presented in the section “Fragment parameters”. 583
Fundamentals. Two-Dimensional Design 584 The values of the fragment external variables are specified in the section “Variables” of the properties window. This section is present in the dialog of the command's properties window if the fragment being inserted has external variables. In the section “Preview” of the command dialog the inserted fragment is dynamically displayed in accordance with the specified values of the external variables, fixing elements (fixing points and fixing vectors) are indicated. When defining fragment insertion parameters, you need to specify the placement points of the fixing vector or fixing point in the drawing area (see the section “Defining Fragment Placement in the Assembly Drawing”). The coordinates of the specified points are shown in the section “Coordinates” of the command's properties window. After attaching the fragment on the current drawing, it is necessary to finish creating the fragment by pressing in the automenu or in the command's properties window. Before that a series of additional operations can be performed with the help of the options appearing in the automenu of the command at this stage of the fragment insertion: Input Fragment insertion points Set Fragment Parameters Create Name for selected Element Open Part Open Fragment in Context of Assembly Automatic Explode Explode with Construction Open Fragment file for editing Select Clipping Hatch Select Other Element Deselect all elements The option starts the mode of respecifying the fixing point of the fragment. The option allows assigning the name for the inserted fragment. The fragment name can be used, for example, for search, for automatic creation of nodes of the fragment in the assembly, for obtaining the values of the fragment variables in the assembly drawing with the help of the function get: get («Fragment name»,« Variable name»), where «Fragment name» – the name that was specified for the fragment, and «Variable name» − the name of the variable from the fragment drawing the value of which has to be obtained in the assembly drawing. To explode the fragment automatically the options and are used (see the section “Exploding Fragments” in the chapter “Basic Fundamentals and Concepts of Working with Assemblies”). The options

The values of the fragment external variables are specified in the section “Variables” of the properties<br />
window. This section is present in the dialog of the command's properties window if the fragment being<br />
inserted has external variables.<br />
In the section “Preview” of the command dialog the inserted fragment is dynamically displayed in<br />
accordance with the specified values of the external variables, fixing elements (fixing points and fixing<br />
vectors) are indicated.<br />
When defining fragment insertion parameters, you need to specify the placement points of the fixing vector<br />
or fixing point in the drawing area (see the section “Defining Fragment Placement in the Assembly<br />
Drawing”). The coordinates of the specified points are shown in the section “Coordinates” of the<br />
command's properties window.<br />
After attaching the fragment on the current drawing, it is necessary to finish creating the fragment by<br />
pressing in the automenu or in the command's properties window. Before that a series of additional<br />
operations can be performed with the help of the options appearing in the automenu of the command at this<br />
stage of the fragment insertion:<br />

the variable from the fragment drawing the value of which has to be obtained in the assembly drawing.<br />
To explode the fragment automatically the options and are used (see the section “Exploding<br />
