This is a spreadsheet that's useful for calculating the angle difference between two bearings. This is particularly useful when redrawing parcels and rotating parcels from different plats/deeds to fit together.

A good and thorough workflow[edit]
- Select and "start editing" the shape you want to rotate
- Drag a box to select all the vertices (or open the vertex list, click the number area of a vertex, hit ctrl+a, then check one of the boxes)
- Drag a vertex to its counterpart on the feature you're matching
- Switch to the "create feature" tool for either a line or polygon class
- Add a vertex on the matched corner
- Bring the excel spreadsheet in to focus
- In arcmap, mouse over a different shared vertex on the feature you'll rotate, which is still selected
- Enter the bearing from the status bar in to the spreadsheet
- Mouse over the counterpart to the second vertex
- Enter the second bearing
- Select the rotate tool in arcmap
- Hit ctrl+z to undo adding the vertex
- Hit 'a' to bring up the angle entry for the rotate tool
- Enter the numbers from the highlighted row, with dashes between them
- Hit enter
- Edit and reselect all the vertices and move the vertex so it's coincident again
- Adjust other vertices as needed, which is likely
Tips[edit]
- The negative sign is in the field in front of the first number, so don't miss it
- Choose an initial vertex that is part of a good long common line, if possible
