Quick way to recreate long series of curves from arc specs?

[autoMick]

I have a copy of an old plan showing curved boundaries which I wish to recreate in C3D. There's lots of connecting arcs, all of which are annotated like:

RAD 15

CHORD 21.213

  121°22'15"

ARC 23.56

T.L. 15

I can see that the first line is the radius, the 2nd and 3rd lines are the length and orientation of the arc chord, the 4th line is the arc length. I actually have no idea what T.L. is (it's not always the same as RAD) but I guess it's something obvious?

I've been able to get a correct result by firstly drawing the chords, then adding arcs with the appropriate radii between the two ends of each chord. However, I'm sure there's a quicker and easier way. Sometimes the arcs are separated by short sections of straight line which have length and bearing details as well. 

Attached is a screen shot of a short length

Any suggestions for an efficient workflow?

Thanks

T.L. = Tangent Length would be my guess - you could extend the chords to the Intersection Point as a check

I'm hoping you have this a vaniila CAD File? Perhaps you could isolate all the straights and use FILLET with the specific radius to join each one?

OK thanks Neiljy, Tangent Length is correct. 

The drawing is a scanned pdf. The original file cannot be located. So I have to recreate the geometry using the arc parameters provided.

Don't think there's a quicker way to do it over what you are doing now 😞
