How do I draw these angles in from this survey plan?

Hi and welcome to AutoCAD Forum,

Enter the point using distance < bearing (@distance<bearing)

(Use d for degrees,  '  for minutes, " for seconds).

Command:  LINE
Specify first point:  select any point Or any known one
Specify next point or [Undo]:  @63.171<125d39'50"

Keep going for all other distances till you reach to the final shape depending on given numbers.

How do i handle those arc lengths? 

Does the "a=63.171" represent the length of the line and then "140d30'26" represents the angle of the line as an arc? 

It just not coming out how it looks on the drawing when i try to map it, so i'm confused.

Thank you!

a=51.268     /     r=72.500

draw a Line with 51.268 total dimension then draw the Arc from both line ends with ( Start,End,Radius ) option.

The "a=63.171" represents the arc (curved) length of the line, and the "140° 30' 26"" represents the whole circle bearing to the centre of the circle, whose radius is given by "r=243.840"

You will note that there is a dotted line at right angles to the arc at each end, and these tell you the bearings at each end. You will also note that these bearings are not exactly at 90° to the bearings of the preceding straights, so the whole survey is not exactly precise, but suffices for a survey drawing.

To use these angles directly, you should set your angle direction to clockwise and have the zero angle at North. The units are in metres.

Arcs can be done as my previous attached image massage #4

Lines ... as i mention it for you in my first massage #2

If you do not mind my asking, where did your survey plan come from (state/country)?

[R_Tweed]

Here is a method to draw arc that will fit within dimensional tolerances.

1. Draw circle with radius shown.

2. Draw reference angles used to locate start and end of arc.   (dashed line with open circle)

3. Draw arc using center, start and end. Using the center of circle drawn and angle points.  The arc length will be close but not accurate due to the angle values used.

4. Use lengthen to make arc the total length as given.

5. Rotate your arc using center and mid point to align the mid point with a bisecting line of the tow angles drawn.  This will center the arc and overlap the two angle slightly.

6. Rotate the angles to match arc end points. ( check angle against current units) it will display proper angle as the adjustment is within accuracy limits.

I've attached a dwg of example.
