http://postimage.org/image/jr35rwdel/ the image above represents spacing rules for engineer stuff. if you look at it you will see the spacing can be summarized as: 1. 7 foot radius circle drawn around the center point of the rectangle. This never changes no matter what the dimensions of the rectangle. So we can ignore this. 2. On the south side of the rectangle, starting at the left and right corners, a 30 degree line is drawn (making a triangle ABC). Once the line reaches the 7 foot radius circle, it only goes 13 foot past it and then curves like a partial circle, keeping 20 feet maximum distance away from the center of the rectangle at all times. This changes if the rectangle size is manipulated. What I need is a way to put this into mathematica or some other program so I can make it interactive and say, okay my rectangle is 2 foot long and 1 foot wide. Then the drawing would update and show what it looks like with that size rectangle, and then if someone needed the rectangle needs to be 3 foot long and 1.5 foot wide, it would auto update again without having to manually re-calculate by hand each time?
