When we draw a line in autocad we can see dynamic inputs for length and angle. can we define another value to display ( new value = length of the line being displayed x constant) at the edge of the line . So that we can observe how that value changes while moving the second point of the line.Your suggestions greatly appreciated.

You are limited to the options that are available via Dynamic Input > Settings.  Right-click on the Dynamic Input button to see what is available.  There are additional settings under the headings Pointer Input and Dimension Input.  All this is hard coded so if you don't find what you want you're out of luck.

Thanks I will try .Appreciate your guidance.
