+In this dialog:
+- Input or accept the default \b Name of the resulting shape.
+- Click the arrow button and select in the Object Browser or in the Viewer the <b>Objects</b> to be fused.
+- Activate the corresponding check-box if you wish to <b> Detect Self-intersections </b>.
+- Activate the corresponding check-box if you wish to <b> remove extra edges </b>.
+- Activate \ref restore_presentation_parameters_page "Advanced options" if required.
+- Press "Apply" or "Apply & Close" button to get the result (GEOM_Object).

+\note This algorithm does not find all types of self-intersections. It is tuned
+ to detect vertex/vertex, vertex/edge, edge/edge, vertex/face and edge/face
+ intersections. Face/face intersections detection is switched off as it
+ is a time-consuming operation that gives an impact on performance. To find
+ all self-intersections use \ref check_self_intersections_page
+ "Detect Self-intersection tool".
+
+This operation can be performed using a <b>TUI Command:</b>
+
+<em>geompy.MakeFuseList(theShapesList, checkSelfInte, rmExtraEdges)</em>
+
+<b>Arguments:</b> Name + a list of shapes + an optional flag for
+self-intersection check + an optional flag to remove extra edges.
+
+There is also a special <b>TUI Command</b> for \b Fuse operation on two shapes :
+
+<em>geompy.MakeFuse(s1, s2, checkSelfInte, rmExtraEdges)</em>
+
+<b>Arguments:</b> Name + 2 shapes + an optional flag for self-intersection
+check + an optional flag to remove extra edges.
