Leaf area index. Leaf area index (LAI) is a dimensionless quantity that characterizes plant canopies. It is defined as the one-sided green leaf area per unit ground surface area (LAI = leaf area / ground area, m2 / m2) in broadleaf canopies. LAI ranges from 0 (bare ground) to over 10 (dense conifer forests).
Now we get the coordinate. Try to activate circle or any other tool. When AutoCAD ask you for the center, click paste value to command line from AutoCAD calculator. Press [enter] then you get the center point at the middle of the two referenced points!A midpoint even there is no lines! You can also use snaps in calculator input.sing Mid Between 2 Points. This is the easiest way to find a midpoint between two points. You can simply choose it from snap tools. You can hold [shift] then press right button mouse then choose it from the list (see shift tips no.1 here). Or you can type _M2P to activate it from command line.
