Created attachment 157438 [details] Example showing style and form names The name of the style for dimension lines is misleading, as it says "arrow line", whereas lines with arrows have the style "default". I propose to call the style "dimension line", too. The attachment shows the name of the form at the left and the name of the style at the right.
Drawing styles are applied to objects. The idea is to draw a line and apply "Arrow Line" to it in order to have arrow heads. The dimension consists of many elements but is basically also an arrowed line. The problem with drawing styles is that we cannot cover all attributes. There is no standard for a color, thickness, and all variations around drawings. And to remove all examples from the styles deck is also not a good solution. I would resolve the issue as WF.

Indeed I didn't look carefully enough at the case, so I overlooked that the style covers a wider range than the measure line. I set the bug to RESOLVED/WORKSFORME.
