A slope describes the steepness of a line. It is also known as gradient. The slope or gradient of a straight line can be calculated when  points (Level 1) and (Level 2) are given. In this calculator, you can find the slope and equation of the straight line with two given points (two point slope form).  What is new in Ver. 2.1  Tangentangent of a Circle Calculator  A tangent intersects a circle in exactly one place. It is a line which touches a circle or ellipse at just one point. The square of the length of tangent segment equals to the difference of the square of length of the radius and square of the distance between circle center and exterior point. Length of the tangent from a point can be calculated from circle radius and angle using this Tangent of a Circle Calculator.

1. Load the LISP using APPLOAD command (AP) 2. Draw or select a line along the longest side of the property, building, etc.  3. Type "ROD" command to activate the lisp. 4. Select the line or object. 5. Done "This can also be done in a viewport without affecting model space, but you will need to reset the VP scale." Notes : Rotating your UCS to an object is a very quick way to rotate your drawing's view so that it is aligned with a major object in your drawing. This works very well when you want to rotate the view in a viewport. It is instant and it rotates the view to the angle of the object you select. To put things back to normal, type PLAN on the Command line and choose WORLD, then type UCS and select WORLD.
