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.
The term Centric refers to the way a wheel is centered. In other words a hub centric wheel centers on the hub of the car, if you put the wheel on the car without lug nuts the wheel would be perfectly centered. On a lug centric wheel, the wheels are centered by the lugs as they are tightened down.or example: the center bore of all 4x100mm and 5x100mm wheels is 64mm. However, the hub diameter of the Honda is 56.1mm. Therefore to take up the space between 64mm and 56.1mm a hub ring is used.
