Geometric Dimensioning and Tolerancing Symbols. Datum symbols Precision. Takes integer values in the range from 3 to 16, inclusive. This parameter makes sense only when using the automatic tolerance calculation. Value. This is the value of the tolerance, either input manually or calculated automatically. A predefined list of values is supplied for the manual parameter definition. Datum 1, Datum 2 and Datum 3. These are the names of datums that can be used in the GD&T symbol, defined as textual strings. Text variables can be used as datum names just like in the case of any other text string parameters. Setting. Can be set or unset. If set, the dimension value will be entered after the tolerance value. Text after. This parameter allows entering an arbitrary text string that you want to be displayed after the tolerance value. You can enter, for instance, conditions for dependencies, unevenness, etc. Use the key combination for this purpose. If necessary, use variables in this entry, surrounded in braces. Rotation. Can be set or unset. If set, the GD&T symbol will be rotated by 90 degrees. Location. Defines the box positioning with respect to the attachment node. Eight different positioning options are provided in the pulldown menu. Level, Priority, Color and Layer have the same purpose as for other drawing elements. Font parameters. The tab “Font” provides the means for setting the font to use in rendering the notations. Keep in mind that the settings affect the size of the notation itself. Set as default. Setting this parameter means that all newly created GD&T symbols will use the current settings. If you select the radio button “Datum”, then you will have to define a different, shorter, list of parameters: Datum, Location and the general system parameters: Level, Priority, Color and Layer. Once you defined the GD&T or datum symbol parameters, the respective notation will be displayed in the drawing. Follow are the examples of various GD&T symbols of surface geometrical dimensioning and tolerancing. 385
<strong>Fundamentals</strong>. Two-Dimensional <strong>Design</strong> 386 Show parameters dialog on creation. With this parameter set, the parameters dialog box will appear automatically when creating a GD&T or datum symbol. This parameter is only provided in the dialog when called from the GD&T symbol creation command. Editing GD&T Symbols To edit GD&T symbol parameters, position, attachment or to set or break the relation between a GD&T symbol and a drawing dimension, use the command “EFO: Edit GD&T Symbols”: Keyboard Textual Menu Icon “Edit|Draw|GD&T Symbols” Upon calling the command, the following icons are available in the automenu: Select All Elements Exit command You can select a GD&T symbol by pointing it with the mouse and clicking , or by using multiple selections. As in the case of other drawing elements, the multiple selections are done by the option . Using together with the depressed key adds an element to the list of selected, while with the key - removes from the list of selected. For multiple selections, you can use the options: Set GD&T (Datum) Symbol parameters Delete selected Element(s) Cancel selection When selecting one element, the following icons become available in the automenu: Set GD&T (Datum) Symbol parameters Select Node Select GD&T Symbol Set relation with Dimension Break (kill) relations Select Other Element Delete selected Element(s) Cancel selection
