view boundary line is too big

Hi,

When i am working in SW drawing, some times the view boundary line is too big without any object on that area. Kindly find the attachment. In this view C2-C2, drawing from model is only in far right area. But, the most of the space in the left side is empty. I tried to find out that any hidden object is there. But, i couldn't. I am have the doubt that any base point of the block in this view is present in the left side. But, i have no idea to find out and make the boundary small. Kindly give idea.
