Objects in real life are three dimensional. That means they have a top to bottom size (HEIGHT), they have a side to side size (LENGTH) and they have a front to back size (DEPTH) 120 Sometimes it is best to show how an object looks by using a three dimensional image like the photo 20 shown here of the plane taking off. Other times though, it may be best to describe an object using a series of two dimensional images like these ones shown. This is how it would be done.... FILL IN THE MISSING WORDS . . . . The ELEVATION shows what the object would look like if you looked at it from directly in front of it. The PLAN shows what the object would look like if you looked at it from PLAN The END ELEVATION shows what the object would look like if you looked at it from This kind of line is called a It is used to show LAYOUT Orthographic views always have to be laid out the same way. The PLAN must always be directly above the ELEVATION. The END ELEVATION must always be directly to the left or to the right of the ELEVATION LOOK AT THE EXAMPLE SHOWN !

They could be used to confirm that your understanding of a topicis correct. NAME : DATE : nd They could also be used to guide you in the topics which you fou difficult in class the first time round. They are designed as self help. Go throughthem slowly and if you still don’t get it, go back to your teacher as soon as possible.
