Using this command, you can extrude a sketch to make it as a solid.

1.

Create sketch as the below image.

2.

Click  button on the toolbar, or click Insert > Solid > Extrude. Select Base Sketch. Set Length to 50mm and Draft to 10 degree.

3.

Select the Method. Click OK.

·   Base Sketch – Select the sketch to extrude.

·   Profiles – Select loops to extrude.

<Extrude Loop 1>             <Extrude Loop 2 & 3>

·   Extrude Direction – Select a direction vector in the graphics area to extrude the sketch in a direction other than normal to sketch profile.

·   Method – You can select a method to extrude.

a) Blind: Extends the feature from the sketch plane for a specified
          distance.

b) Through All: Extends the feature from the sketch plane through all
          existing geometry.

c) Up To Vertex: Select a vertex in the graphics area for Vertex.

d) Up To Region: Select a region in the graphics area.

e) Up To Surface: Select a face or plane to extend to in the graphics area
          for Face/Plane.

f) Up To Body: Select the body to extrude to in the graphics area for     
         Solid Body. You can use Up To Body when making    
         extrusions in an assembly to extend the sketch up to the selected
         body. If the sketch that you extrude extends outside of the selected face or
         surface body. Up To Body can do some automatic extension of one 
         analytic face to terminate the extrusion. Up To Body is also useful with
         mold parts, if the body you extrude to has an uneven surface.

g) Mid Plane: Selected sketch plane become middle of extrusion.

·   Draft: You can set Draft On/Off. Adds draft to the extruded feature. Set the Draft Angle. Select Draft outward if necessary.

<Draft: 0>                <Draft: 10>

Note
You can use  to change the direction of draft.

·   Opposite Direction - Set these options to extrude in both directions from the sketch plane. The options are the same as Direction.

·   Result Operator: This option is available when there are two more bodies.
       a) Cut: When the two solids make an intersection, the resultant solid is cut to
          keep only the intersected part.
       b) Merge: The first body is merged with the new extrusion.

Note
If you do not check anything, XOR creates independent body.
