Input fields:
-- **Circle or Arc** is the circe or arc circumference selected in the view
+- **Circle or Arc** is the circle or arc selected in the view;
- **Value** is a radius of the selected object, could be modified to set the desirable value
- **Text location** is a position of the radius value label relating to extension line (in the view)

-When circle or arc is selected radius value is displayed in the property panel and in the view.
+When circle or arc is selected, the radius value is displayed in the property panel and in the view.
When creating the constraint, after selection of the circle or arc at the first time :
-- drag the radius presentation in the view to the desired position (by move mouse and click once)
-- set desirable radius value in the input field in the view and press **Enter** or just press **Enter** to keep the current radius
+- drag the radius presentation in the view to the desired position and click once;
