Now our next step is to remove a solid part which again needs a sketch .the sketch can be drawn by selecting the sketcher option in the part module .just select the part module in the beginning and go to select the sketcher in that by selecting the surface.

Thus the sketch drawn looks as shown in figure

Fig 2.4 sketch on surface

To remove material select the sketch dawn and select the remove option present in the extrusion definition box. So the extrusion can be used as both either you remove the material or to create the material.

Thus the removed cross section looks as shown below

Fig 2.5 extrude used to remove material

Now to apply the round along the edges select the round from the engineering features. the process is shown below.

Fig 2.6 representing round feature

Now to remove material draw the sketch or required sketch that is necessary .that is shown below

Fig 2.7sketch drawn on surface

Our next step is to generate a solid part which again needs a sketch .the sketch can be drawn by selecting the sketcher option in the part module .just select the part module in the beginning and go to select the sketcher in that by selecting the surface.

Now let us see how to do it
