Thank You all for the replies. Yes I did try the view display settings clipping method but the clip is just normal to the screen. I was looking for a way to set the clipping plane say on a 'X' plane for example and slide it rearward in the 'X' direction while in an isometric view 3d view. It would also work in the 'Y' and 'Z' directions as well as setting it up normal to any line and sliding it back and forth.
