cut one side image off

Primely, I am going to do the three side images model, but when I do the third one, I had some difficulties.It is easy to do the one view image, ok to do the two view images,need take long time to do the three view images. I think the model which showing two view images is enough to present one of my idea is combine different things in one object. I made a decision which is give the left view image up and save time to explode and develop my current finish model.
