Drawing Modification via Dimensions Recalculate Dimensions on All Pages. This flag allows performing recalculation of 2D dimensions on all pages of the given document. As a result of recalculation, dimension tolerances become symmetrical. The manual method of defining tolerances will be set in the parameters of recalculated dimensions. The tolerance values can be assigned either symmetrical values resulting from the recalculation or zero values. The choice is made by setting/clearing the flag “Delete Symmetrical Tolerances”. When the flag is cleared, the parameters of recalculated dimensions are assigned symmetrical tolerances, whereas when the flag is set – zero tolerances. When previewing the recalculation result (the option ), the system highlights with different colors the dimensions that it successfully recalculated to the middle of the tolerance range, along with those that couldn't be recalculated, or those recalculated incorrectly. By default, the correctly recalculated dimensions are marked blue, the incorrectly recalculated ones – red. If necessary, you can specify your own highlight colors in the properties window. 459
Fundamentals. Two-Dimensional Design RELATIONS 460 To quickly track geometrical dependencies in drawings and manage them, T-FLEX CAD has a special type of 2D elements – Relations. Relations serve to visually render on the drawing screen the types and parameters of geometrical dependencies between construction elements. Using the relations one can modify parameters of those dependencies without calling the editing commands of the respective construction elements. Relations are auxiliary objects that are displayed in the drawing field in the way of special marks. Those are not printed and are not exported. The information about the type of the geometrical dependency and the numerical parameter of the object, to which a relation pertains, is displayed on the relation mark. If a parameter is related with an expression or with a variable, then the relation mark displays both the expression and its current value. Relations can be created automatically by the system (“temporary Relations”) or manually by the user. The automatic creation is done in the command for editing construction lines and graphic lines created based on construction lines. The system creates relations and displays them on the screen: if a construction line is edited – then for that line itself, if a graphic line is edited – then for the construction line, on whose base the graphic line is created. When exiting the editing command, such Relations are deleted automatically. Temporary Relations can be used to modify construction line parameters in the transparent mode. Manual creation of Relations is done by the user in the command “REL: Element Relations”. In this case, it is possible to create Relations either for individual construction elements or for all construction elements in a given drawing. Relations that are explicitly created by the user exist in the drawing up until the user deletes them by the same command. By default, those are permanently displayed in the drawing. Using those you can analyze parametric relations in the model, as well as modify construction line parameters. If necessary, all or specific existing Relations can be hidden from the current 2D window or completely over the entire document (such hidden Relations will not be displayed in any 2D windows opened for this document). Using Relations when Working with Drawings Relations serve the two main purposes: - Visualizing geometrical relations in the model; - Modifying geometrical parameters of the model in the transparent mode. The first goal is achieved by creating Relations, when the user can visually examine geometrical relations without using the command “Help|Information…”. To modify an existing geometrical parameter using Relations, point the mouse at the parameter value in the Relation mark and click . The mark will turn to an edit box displaying the parameter value it controls. Just like in other system fields for editing values, the user can create here the list of frequently used parameter values and use it with the help of a special button for selecting the value from the list. This list is
