Dimensions Besides, special symbols can be entered in the text strings via . To do this, click inside a text string input box and press . Then, select the desired symbol and hit . «Tolerance» section Special symbols are various conventional textual and drawing notations. The symbols are represented by the textual font used in the parameter dialog box. On selecting a special symbol from the dialog box, it will be entered in the parameter string input box as a double percent character (%%) followed by the symbol code. However, upon placing the cursor into the parameter string which contains special symbols, a popup tooltip with a real image of the line contents will appear on the screen. On the drawing the special symbols will be also displayed precisely. Note that the special symbols can be used as part of any parameter, which is a textual string, for various system elements. This section of the properties window defines the tolerance zones and deviation limits. The “Text” parameter, which is coming first in the section, defines what parameters will be displayed together with the dimension nominal value: Nominal. Only the dimension value is displayed. Nominal + Deviations. The deviation limits are displayed next to the dimension value string. Nominal + Tolerance. The tolerance notation will be displayed next to the dimension value string. All parameters. In this case, both the tolerance notation and the deviation limits are displayed. Limits (ANSI standart). The dimension value string is composed of the two main values, each being the sum of the dimension value and the corresponding deviation limit. Deviations can be defined manually or calculated automatically based on the specified tolerance zone. Automatic deviations calculation is used by default. The change from the manual setting to the automatic is done by toggling the “Deviations” flag (when the flag is off, the deviations are calculated automatically, when it is on – those are defined manually). When using the automatic mode of calculating tolerances, you just need to specify the tolerance zone. Please note that the values of the calculated deviations depend on the measurement units defined in the “Customize|Status…” command menu. Automatic calculation of deviations works only for the millimeters or inches settings. When the dimension value is modified, the deviations populated from tolerances will be adjusted automatically. A variable can be entered in place of a deviation value just like in any other numerical field. 329
<strong>Fundamentals</strong>. Two-Dimensional <strong>Design</strong> Various standards set the different requirements to the font size used to display value deviation limits in the drawing. Two choices are provided: reduced-height, which is half the font size, and full-height. To choose the desired one, use the “Font” parameter. Fit parameters are defined similar to tolerance parameters. «Style» section Sign. For a linear dimension, this parameter defines a special symbol to be displayed before the dimension value. This is necessary to create, for example, a radius, diameter or thread dimension. This parameter is not available for the circular arc length dimension. Type. This parameter is required if you need to have a linear dimension without extension (witness) lines (this is often used when creating dimensions from a centerline). This parameter can also be used to create one-sided dimensions (used for dimensioning on cut views or for dimensions on large-size parts). Strings offset. This parameter defines the distance by which the dimension value string and the string beneath the dimension will be separated from the dimension line or from the leader shelf (by default = 0). Lines offset. This parameter defines the offset of extension (witness) lines of a dimension from the object when creating dimensions per the ANSI and AR_ANSI standards. Whenever this parameter is not defined, the offset amount will depend on the size of the dimension line arrows. 72 72 The diagrams at the right correspond to the values of this parameter equal to “0” and “5”. 330 Box. Turning on the “Box” flag outlines the dimension text by box. Outside Arrows. When this flag is set, the dimension arrows are always drawn outside of the extension (witness) lines. When the flag is disabled (the default), the arrows position is determined automatically depending on the distance between the extension lines of the dimension. If arrows don't fit inside, then those will be automatically switched to outside. The “Clear Background” group provides controls for the dimension display mode in which drawing portions are erased around the dimension strokes: Under Arrows. Turning on this item erases the drawing portions under and around the leader lines and leader arrows (at the distance equal to the thickness of the main continuous line). Under Lines. Turning on this item erases the drawing portions under and around the witness lines (at the distance equal to the thickness of the main continuous line). In the case of the radial dimensions, the background is also erased under the cross marking the circle center.
