Hello Micah,
Thank you for your reply.
Sorry, I have made a typing mistake. I meant to write horizontal directions.

I'm asking for this situation. If I set my A coordinates to be (0,0), how do i define azimuth/ bearing ( i chose 90-00-00 deg for image example because it's easier to explain) so it pulls distance form horizontal distance measurments and automatically calculates the coordinates for point B. Or do i have to manually define as (50,0) ?

What I'm trying to do Is free network adjustment 2D (in some local system), but I don't know how to set it up. For free network do i define the point A as (0,0), B(50,0), rest of the points as new points?
