HowFar lisp is a free lisp program to measure the exact distance and the X and Y components between two points (PT1-PT2) in Decimal, Fractional, Engineering, Architectural and Metric. It also gives the angle between the two points in Nearest degree, Decimal degree and degrees/minutes/seconds formats. While the dialog box displays the measurements it allows the user to change the precision of each format from 0 to 8 places precision.

I have recently added a second measurement lisp program for the continous measuring of multiple points.
