Basic Fundamentals and Concepts of Working with Assemblies A fragment that contains nested fragments is exploded into the graphic elements and fragments that it contains. After using the exploding option, the obtained elements can be treated as usual, according to the type. If some elements in the assembly drawing were attached to fragment elements (dimensions, construction lines, etc.), then, upon exploding, those will be re-attached to the elements created by the fragment explosion (nodes, construction and graphic lines). Use of Connectors When creating assembly documents, it is often necessary to relate parameters (variables) of the inserted elements with the parameters of the elements to which the attachment is made. Examples are: setting a ball bearing on a shaft, attaching a cap to a ball bearing, a shaft key to its slot, a nut to a bolt, insertion of a screw or being into a hole, etc. When inserting such elements, the user is required not only to define the main dimension parameters (diameter, length, etc.), but also precisely position the elements being inserted with respect to the target element (selection of the attachment point and direction). One of the ways of solving this task is using “Measuring” mechanism. This mechanism, however, often requires large amount of auxiliary preparations. Connector mechanism helps significantly simplify the procedure of assembling elements and minimize the number of actions required from the user. This mechanism is based on the concept of a “connector” which is a construction element serving as a reference for attaching other elements. In fact, a connector is a counterpart of a fixing vector or a target LCS for attaching 3D fragments. Its main difference from a fixing vector is that a connector serves for providing attachment reference to other model elements. Consider, for instance, use of a fixing vector for inserting a bearing image into an assembly drawing. Suppose, the image of the bearing should be attached to an axle. In this case, the connector should be attached to the axle image (fragment). Besides the geometrical positioning (the origin position and the axes directions), a connector may keep additional information necessary for “snapping” to it other elements. This information is kept in the connector in the form of named values that can be constants or variables. The names of these values are used for specifying the values of the respective external variables of the fragments being snapped to the connector. For example, a connector placed on the axis of a hole, can have such parameters as the hole depth and the diameter. When inserting a pin in this hole, its diameter can be automatically defined by the value D kept in the connector. To achieve this, the external variable defining the in diameter should also be named “D”. There are a number of considerations when using a connector for snapping a fragment: • A connector is a construction entity and may not be displayed in the main drawing, while it has to be selected when snapping a fragment to it. • A connector may be located outside the viewable area of the drawing. • Sometimes, it is convenient to use a connector for placing an element elsewhere. For example, when attaching a cap to a ball bearing, it is convenient to select the outer lines of the ball bearing. Meanwhile, the intended connector is lying on the ball bearing axis. 571
Fundamentals. Two-Dimensional Design 572 A concept of “associated elements” is introduced for dealing with such questions and for overall convenience. The list of such elements is stored in the connector. Associated elements are necessary for indepth utilization of the object snapping mechanism when snapping to a connector. As the pointer approaches one of the image lines associated with the connector, the connector is automatically activated (highlighted in the screen), and the external variables of the fragment receive the values from the connector. The 2D fragment is automatically calculated with the new variable values and is snapped to the attachment point with the appropriate orientation. All libraries of the standard T-FLEX CAD elements are already equipped with connectors and ready for their use. The required named values for linking with the connectors have been set in advance for the driving external variables. Composition Document. Embedded Fragments T-FLEX CAD provides a mechanism for managing references to other documents (fragments, pictures, external databases, etc.). A T-FLEX CAD document may contain references to external files ("external link") or have the external file data embedded directly within the file of the composition (assembly) document in T- FLEX CAD (“internal link”). This mechanism also helps quickly port an assembly model to another location in the file system, zipping the assembly in one file with the capability of quickly unzipping it later. The “File|Assembly…” group of commands is often used in the system to manage references. Working with commands of this group is described in the chapter “Links. Managing Composite Documents”. Keyboard Textual Menu Icon “File|Assembly|Update Links” “File|Assembly|Update Assembly” “File|Assembly|Links…” “File|Assembly|Move Assembly…” The command “UL: Update Links” redownloads data from the external files of the first level which are included into the composition document. The command “UA: Update Assembly” redownloads data from the external files and embedded documents as well. The command “AL: Links” is provided for managing the assembly document links to other documents. Each of the links can be assigned a type defining the position of the external file. The command “AM: Move Assembly” is provided for moving an assembly document to another location in the file system or for zipping the assembly into one file. When moving the file, the moving options can be specified (embedding, substitution), as well as the name and the path to the target document of moving the assembly.
