Using Call Draft

Set the POB northing and easting (0,0 is fine for a sketch).
Add a line with + Line and type the bearing and distance. Enter moves to the next cell.
Read closure, precision and area in the bar under the grid. Export DXF, PDF, CSV or .deed, or Save the project.

Bearing entry

Numbers with a decimal point are D.MMSS: 45.3020 is 45°30′20″. If the fraction is not valid minutes and seconds it is read as decimal degrees.

N45.3020E      quadrant
1 45.3020      code 1=NE 2=SE 3=SW 4=NW
123.4530       azimuth
N 45 30 20 E   spaced DMS
N45.3020E 150.5  bearing + distance

Unreadable bearings outline red and stay in the grid and the save file with a warning.

Distances and units

Pick feet, varas, chains, links, rods, yards or meters per row. Grouped numbers such as 1,200.50 work. Negative distances plot as entered and are flagged.

Curves

Give any two of R, Arc, Δ and Chord, plus a chord bearing or let the tangent be assumed. The first computable pair is used in this order: R+Δ, R+L, R+C, Δ+C, Δ+L, L+C. Extra values are checked and flagged if they disagree.

Ties, witnesses and tracts

A tie is plotted dashed and left out of closure and area. A tract that starts with a tie commences at a P.O.C.; the P.O.B. is where the ties land. + Tract starts another tract; a row's » splits the tract at that call.

Balance, rotate, blunder

Balance distributes a misclosure over the line courses by the compass rule, holding curves. Rotate turns the plot and every exported coordinate for a different basis of bearings. Find blunder suggests the one call that would close a poor traverse. Undo reverses each.

Files

Save writes a .ds2.json project (Deed Sketch v2 format). Open or drop reads .ds2.json and legacy .deed files. DXF is AC1015 with NCS V- layers per tract; PDF is a plot sheet plus closure report; CSV is the corner table.

Record, not survey

The plot is drawn from record calls. It is not a boundary survey.
