 Tangent constraint
 ==================
 
+Tangent constraint fixes a circle (or an arc) and a line so that a line is tangent to a circle (or an arc).

+To create a Tangent in the active Sketch:
+
+#. select in the Main Menu *Sketch - > Tangent* item  or
+#. click **Tangent** button in Sketch toolbar:
+

+   :align: center
+
+Input fields:
+
+- **First object** is a line, a circle or an arc selected in the view.
+- **Second object** is a line, a circle or an arc selected in the view.
+
+Note that one of two objects should be a line.
+
+After the objects are selected, a special sign will be added close to the tangency point in the view.
+
+**TUI Command**: *Sketch_1.setTangent(Line, CircleOrArc)*
+
+**Arguments**:  2 objects (the first is a line, the second one is a circle or an arc)
+
+Result
