+
+Sketch Drawer
+=========
+
+Sketch Drawer featrure is a macro-feature, i.e. it is removed after its execution.
+It allows simplify creation of sketches basing on existing models without referencing to
+these models.
+
+For an example, to create a sketch on exising STEP file model planar face
+and then remove the original model, to keep only the sketch with copy of contour. So, to be
+able to remove the initial model, there are no references created by this feature.
+
+To add a new Sketch Drawing:
+
+#. select in the Main Menu *Macros - > Sketch drawer* item or
+#. click **Sketch drawer** button in Macros toolbar:
+
+.. image:: images/SketchDrawer.png
+ :align: center
+
+.. centered::
+ **Sketch drawer** button
+
+The following property panel appears:
+
+.. image:: images/SketchDrawer_panel.png
+ :align: center
+
+.. centered::
+ Sketch drawer
+
+Click in the view once to set the whole original model, then click a second time to set the
+plane or planar face - a base of sketch. This can be plane on the original model.
+On Apply button press the new sketch will be created in the Object Browser tree.
+
+Result
+""""""
+
+A resulting sketch will contain linear and circular edges as well as circular arcs corresponding to the
+original model edges that lay in the sketch plane. Other types of edges are not supported.
+
+Radius, length, vertical, horizontal and points-coincidence constraints will be created
+automatically where it is possible. The resulting sketch may be overconstrained or not fully
+constrained. So, it is just a helper for the sketch creation, not universal tool. After this
+sketch creation normally user must edit this sketch to input reasonable constraints and
+parametrization, or remove not needed constraints or sketch lements.
