For radius dimensions, you can activate the Foreshortened option
in the contextual menu Properties -> Dimension Line.
It allows you to transform a radius dimension line into a foreshortened radius dimension line. Then you can choose the text position (on long segment or short segment), the dimension text orientation according to the dimension line ( parallel or convergent), the angle value, the ratio value (short segment/long segment), and the point scale value. |

You can also specify whether you want to unfix the extremity point of the foreshortened dimension line, which will let you move the extremity point using a yellow manipulator. | |||||||||
