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