Distance constraint
===================
+Distance constraint fixes the distance between two objects.
-.. image:: images/Distance.png
- :align: center
+The constraint can be defined between such objects as point, line, line or arc end point, center of circle or arc.
-.. centered::
- Create a distance constraint
+To create a Distance constraint in the active Sketch:
+
+#. select in the Main Menu *Sketch - > Distance* item or
+#. click |distance.icon| **Distance** button in Sketch toolbar:
+
+Property panel:
+
+.. figure:: images/Distance_panel.png
+ :align: center
+
+.. |location_left| image:: images/location_left.png
+.. |location_auto| image:: images/location_automatic.png
+.. |location_right| image:: images/location_right.png
+
+Input fields:
+
+- **First object** is the first object selected in the view;
+- **Second object** is the second object selected in the view;
+- **Value** is a distance between the objects, can be modified to set the desirable value;
+- **Text location** is a position of the distance value label relating to extension line (in the view):
+ | |location_left| **Left** inserts text to the left of the distance extension line;
+ | |location_auto| **Automatic** inserts text in the middle of the distance extension line if it has enough length, otherwise - to the left;
+ | |location_right| **Right** inserts text to the right of the distance extension line;
+- **Keep orientation** fixes the relative position between selected objects.
+
+When both objects are selected, the distance value is displayed in the property panel and in the view.
+
+When creating a constraint after selection of two objects for the first time:
+
+- drag the distance presentation in the view to the desired position and click once;
+- set the desirable distance value in the input field and press **Enter** or just press **Enter** to keep the current distance.
