Dimension styles

How a dimension or text is displayed is set by the style it uses. All the tools invoke a menu from which a style can be chosen. Initially there is one default style. By selecting Edit Styles..., more styles can be created in the Dimensions dialog. The same dialog can also be invoked from the Dimensions tab of the Project Settings dialog.

On the left side of the dialog a list of available styles is shown. New styles can be created with the Add (Add) button and existing styles are deleted with the Remove button. The parameters of the highlighted style in the list are shown on the right side of the dialog.

 

The Type popup menu has two items: Screen and World. They specify how the values entered in the dialog will be interpreted. Screen values remain the same regardless of the scale of a drawing, while world values are affected by the zoom factor and are scaled accordingly.

 

The Text group of options specifies the details of the text appearance. Size and Gutter control how big it will be and how much space around it should be left blank. The Font menu offers a choice of fonts currently installed on the system. When Include Units is checked, unit measurement indications will also be displayed. The text currently specified is displayed in the Text Sample box.

 

The two Orientation options determine whether the text is displayed in the plane of the dimension (Aligned With Dimension) or the text is drawn flat on the screen (Horizontal On Screen). See examples below.

There are three Placement options that determine if the text will be placed Above, On (default), or Under the dimension line. Text Between Witness Lines controls whether the text will always be placed between the witness lines, even when it needs extra scaling to fit.

 

The Terminator group specifies whether a terminator symbol will be placed at the Start and/or End of a dimension line. This can be one of a variety of available options or None. See examples below.

Terminator types: (a) Open Arrow, (b) Filled Arrow, (c) Dot, (d) Slash, and (e) None.

 

The Witness Line group controls whether there will be such lines at Start and/or End and contains options for their specification.

 

The measured quantities of a dimension are rounded by the values in the Display Accuracy fields. If no rounding is desired, zeroes should be entered, in which case the accuracy in the Working Units tab of the Project Settings dialog will be used.

 

The last two options determine if dimensions and text are dropped from the display, due to that they are viewed at a shallow angle or become very small because of zooming too far. If Hide Dimensions By Screen Size and Hide Dimensions By View Angle are checked, dimensions shorter than the indicated screen size or viewed at an angle less than the one specified are not displayed.
