Dimensions Auto-Scale. The deviation limit values are calculated by the tolerance zone of the main dimension (while accounting for the measurement units of the alternative dimension – millimeters or inches). The definition of the tolerance zone value of an alternative dimension does not affect the calculation of its value deviation limits. Auto-ANSI. Deviations are calculated by the defined tolerance zone of an alternative dimension per the ANSI standard. Auto-ISO. Deviations are calculated by the defined tolerance zone of an alternative dimension per the ISO standard. Manually. The deviation values are defined by the user. Variables can be used instead of deviation values. When using the automatic modes of calculating deviations (Auto-Scale, Auto-ANSI or Auto-ISO), you just need to define the tolerance zone. The deviations will be calculated automatically. Accuracy. Defines the rounding precision of the dimension values of the alternative linear dimensions. For example, the accuracy 0.01 means the dimension values will be rounded to the second decimal digit. Accuracy 0 means no rounding. If set to “Default”, the accuracy assumes the settings from the “Alternative dimensions” tab of the “Customize|Status …” command. Units. Defines the way of displaying the dimension values of alternative linear dimensions. This item is primarily used when working in inches. Just as in the previous case, the “Default” setting means the dimension will be displayed in the units defined on the “Alternative dimensions” tab of the “Customize|Status…” command. Minimum Digits. This parameter determines the minimum number of decimal digits that is displayed for the alternative dimension value (similar to the “Minimum Digits” parameter of the main dimension value). If “Default” is set, then the value is taken from the “Alternative dimensions” tab of the “Customize|Status…” command. «Options» section The section contains only one auxiliary parameter– “Show Dialog for each Created Dimension”. If this parameter is enabled, then the dimension parameters dialog will automatically appear after defining the dimension position in the dimension creation command (the option ). This mode allows working in the same way as in previous versions of T-FLEX CAD – by specifying the dimension position in the drawing first, and then defining its parameters. Special about Defining Angular Dimension Parameters Linear and angular dimension parameters are mainly same. Described below are the existing differencies. The set of tolerance parameters for angular dimensions is different from the respective parameters of other dimensions. Since angular dimension tolerance calculation depends on the length, the parameter “Length” is provided for angular dimensions. When calculating deviations automatically, the following formula of defining the tolerance zone is used: +AT8, AT8 or -AТ8, where 8 is the tolerance grade, while a signed AT defines the tolerance type. 333
Fundamentals. Two-Dimensional Design 334 +AT The deviations are calculated in degrees, minutes and seconds, respectively. The angular dimensions use special units for displaying the dimension value. For angular dimensions you cannot specify an alternative scale, nor any other parameters related to an alternative dimension. Special about Defining Parameters for Dimensions on Circles In the “Style” section you can enable the display of a small cross at the center of the circle on which the dimension is created (the “Cross in Center” parameter). This is required by some standards. Otherwise, the parameters for circles correspond with the parameters for linear dimensions. Special about Defining Parameters of Ordinate Dimensions Ordinate dimension parameters are mainly same as those of linear dimensions. Described below are the existing differencies. The ordinate dimensions do not have the parameters to define tolerances and deviation limits. In the “Style” section there are only the parameters, whose status is relevant to an ordinate dimension. Besides, there are the following additional parameters: Leader Line. Controls the leader extension creation between the dimension and the attachment node. Show “plus”. Controls the display of the “+” sign in dimensions with positive offset from the base dimension. Just as for angular dimensions, there is no alternative scale for ordinate dimensions, nor any other parameters related to an alternative dimension. Working with the dimension parameters dialog You can also define dimension parameters in the parameters dialog called by the automenu option: Set Dimension Parameters The parameters located on the tabs of this dialog duplicate the parameters in the properties window. Besides that, the parameters dialog has a number of additional settings. First of all, that's the system-wise parameters: level, layer, priority and color. The parameters dialog also has an additional tab that contains the font settings. This tab is standard for various system elements (dimensions, annotation leaders, roughness symbols, GD&T formlimits). It allows defining all necessary font settings used to display the dimension value string. If the value of some of the parameters on the tab is set as “Default”, then it will be taken from the “Font” tab of the “Customize|Status…” command dialog. Parameters for New Dimensions (Default Parameters) The default parameters that will be applied to all newly created dimensions can be defined in a number of ways. -AT AT
