I work with floor plans with grid bubbles. On occasion, I want to issue a change to a drawing, but only publish the affected area in an 8-1/2 x 11 submittal. I have three viewports: One (essentially) square view port which shows the area of the plan I'm interested in. One rectangular view port to the right of the square one. It is narrow in width but the same height as the square one. This is used to show the grid bubbles on the side of the plan. One rectangular view port above the square one. It is narrow in height but the same width as the square one. This is used to show the grid bubbles on the top of the plan. Whenever I pan to show a new area of the floor plan, I have to (manually) adjust the retangular view ports so that they show the correct relationship with the floor plan. To do this I usually draw to orthogonal rays and "eyeball" it in. Is there a better way to do this? Thanks, Bill
