Dimension Arc Tool
This tool allows you to draw a dimension arc.
In the tool's dialog:
Tolerance choices are handled as four dimension styles. As you click on these choices, the text editing boxes for the dimension and tolerances change. In the case of limit tolerances, you can only edit the tolerances.
You can change the choice for whether the dimension text is to be rotated, however rotated text does not work on dimension arcs. Click on the button repeatedly to toggle between the two choices.
You have a choice of angular accuracy. These are degrees up to four decimal places, degrees and minutes or degrees, minutes and seconds.
You may type in the dimension text editing box. This allows you to place a prefix or suffix in the dimension text. The angular values will be placed between the up-carets (^).
If the up-carets are removed, no angular value will be placed in the drawing and the text for the dimension will be exactly what you typed. A carriage return can be placed in the dimension text by pressing the Return key. (Because of this, you may use the Enter key alone as a shortcut for clicking on the OK button in the dialog.)
In case you forget the '^DIM^' syntax, a reset button is provided to reset the angular dimension text.
To draw a dimension arc, use the same drawing method used for the Arc by Center tool.
