Thanks, everyone.
If I were to explain it _the object snap tracking feature where we track an activated Object snap or a temporary point to locate a specific point in tandem with the polar angle setting or even the Ortho function is how I find it useful but when I have the Dynamic Input turned on while trying to do the same thing, Autocad always accepts every key press as either a length or an angle value. It helped track ( and track alone) an activated Object snap it didn't let me specify a distance value and locate a new point by typing in the required distance.
As I had Line command activated and after picking the start point, trying to locate the endpoint from an activated Object snap at a required distance- Upon typing in the distance, Autocad assumed I was entering the length of the Line and hence after specifying the distance and hitting Enter key it gave me a Line of length equalling the typed reference Length.
I think I've said it all, every step that I took. One of my friends also complained of the same thing.
I guess, maybe that is how Dynamic Input works or that is one drawback. Any help is appreciated.
Thank You all.
