Introduction:

Sometimes when drawing a technical drawing, to properly instruct the manufacturer as to how the item

is to be built it is necessary to show the inside of the project. This is done by drawing a section. A section

drawing is the view of an object showing what it would look like if it were cut open along what is called

the cut line. Imagine cutting along an imaginary cut line and looking into the object. A cut line may be

shown on any view: top, front, or left side view. This cut line will inform the manufacturer where the cut

for the section view is made, what angle the view will show, and the letter indicating where the drawing

may be found.

For example, to properly construct the cd holder, the builder needs to know the size of the shelves and

how they will be attached. Because that information cannot be seen from any of the three views we

provided, we will need to show the inside of the holder. That is best accomplished by cutting the cd holder

open vertically. As you can see, on the front view we have drawn a section line, or cut line, indicating the

direction of the view the section will show. The result is shown below.
