Comment of variable Variables If necessary, for any variable the comment can be specified. It represents itself an arbitrary text string. The comment enables to “attach” certain clarifications to the variable. For example, the comment may clarify the variable's designation (the width of the part, the radius of the circle, etc.) or the range in which the value of the variable is changed. The comment of the variable, if it is specified, will appear in the dialog for inserting a variable (this dialog can be called, for example, from the context menu of all fields of the system dialogs), and also from the list of the values of the fragment upon its insertion into a drawing or 3D model. Group of variables If necessary, for any variable the group can be identified. When the variables are broken down into the groups, it becomes easier to control the large list of variables of the complicated drawing. The Group, as well as the comment, is an additional characteristic of the variable specified for simplifying the work with a large number of variables. The fact that the variable belongs to a certain group does not affect in any way the use of this variable. External Variables Any variable, the value of which is specified by a constant (numeric or character), can be given an attribute “external”. External variables are used for organizing parametric connection between the assembly document and the fragments. The values of the external variables, defined in the fragment, can be modified from the assembly document. The variables, marked as external, can be exported to the external text file with the possibility of reading from this file afterwards. This enables to use external variables for organizing connection between the T- FLEX CAD and other systems and application programs. Hidden Variables For regulating the work with a large number of variables, the mechanism of hidden variables can also be used. Any variable, created in the T-FLEX CAD document, can be marked as hidden. By default, such variables are not displayed in the window of the variables editor or in the windows of other T-FLEX CAD dialogs dealing with the variables. Thus, it is possible to hide various auxiliary variables. 469
Fundamentals. Two-Dimensional Design 470 All standard templates of the T-FLEX CAD documents already contain a list of hidden variables providing automatic cross-reference between the fields of the drawing format (the title block) and the BOM data. In other words, the textual strings of these variables are substituted in both the appropriate title block fields and the respective entries of the BOM data. Used and used variables In order that the value of the variable could affect the structure of the drawing (or 3D model) of the given document, it is not sufficient just to create this variable in the T-FLEX CAD document. The given variable has to specify a characteristic of the elements of the drawing or 3D model: location of a line or a node, the radius of a circle, the level of visibility of the image line or 3D bodies, etc. The variables the values of which take part in specifying characteristics of other elements will be further called used. Also, the variable is considered to be used, when its value is used for evaluating the value of another variable. Consequently, the variables the values of which are not used anywhere on the drawing or in the 3D model and also upon calculation of the values of other variables are considered to be unused. Such variables, being equal variables of the T-FLEX CAD document, do not have any influence on its content. Work in Variables Editor Window of Variables Editor The work with the editor can be carried out in two ways. The first way – the work in the main window of the variables editor, called with the help of the command “V: Edit variables”. The dialog box of the given window enables to use the entire functionality of the variables editor and possesses a convenient interface. However, all changes made in the given window will be applied to the model only after closing the window of the dialog box. The second way – is to use a special service window of the system – the window “Variables”. This window offers more limited interface to a user, but it enables to work with the variables in the transparent mode. In this chapter the description of work with the variables editor will be further presented by taking the standard window of the variables editor as an example. However, the same operations can be performed in the window “Variables”. The work with the window “Variables” will be discussed in the section “Working with variables editor in transparent mode” in a more detailed manner. To call the main window of the variables editor, the command “V: Edit variables” is used: Keyboard Textual menu Icon «Parameters|Variables» The window of the variables editor contains the list of all variables of the current T-FLEX CAD document no matter in what way they were created (recall that the new variables can be created not only in the variables editor). Upon calling this command, the window of the variables editor will be empty if no single variable has been created in the document. In the editor window, the variables list is displayed as a table, the form of which can be freely edited by a user. It is possible to modify the number and content of the displayed columns, the parameters for grouping and sorting the rows of the table, parameters of the grid of the table. The variables editor has its own textual menu and the toolbar containing the main commands for working with the variables.
