Plat Plotter has a Calculate Curve Table feature that generates a sequence of points for use in drawing plot lines.

thence South 13°0'00" West 201.05 feet to the beginning of a tangent 180.00 foot radius curve, concave Northwesterly; thence Southerly and Westerly along the arc of said curve through an angle of 98° a distance of 307.87 feet; thence tangent to said curve North 69°00'00" West 255.0 feet to the West line of the Northeast Quarter of the Southeast Quarter of said Section 5; For this example, the straight lines before and after the arc are entered as:

S 13 W 201.05 N 69 W 255.00 The Calculate Curve Table feature will create a sequence of values that can be placed between the above two entries given a Chord & Radius.

How does one get from the:

to the beginning of a tangent 180.00 foot radius curve, concave Northwesterly; thence Southerly and Westerly along the arc of said curve through an angle of 98° a distance of 307.87 feet; thence tangent to said curve to the Chord and Radius values needed by Plat Plotter.
