### Creating a hole in the mechanical part

In the previous sections we drew the profile of the part and we created the surface. In this section we will make a hole, an octagon with a radius of 10 units, in the surface of the part. First we will draw the octagon.

• . Select from the menu Geometry->Create->Object->Polygon to create a regular polygon.
• . Enter 8 as the number of sides of the polygon.
• . Enter (0,0,0) as the center of the polygon.
• . Enter or select (0,0,1) (Positive Z) as the normal of the polygon.
• . Enter 10 as the radius of the polygon and press ENTER. Press ESC to finish the action.
• We get the result as shown in figure 20. As we only need the boundary we should remove the associated surface. Select the option Geometry->Delete->Surfaces and then select the surface of the octagon. Press ESC to finish.
