Make sure it is saved in the Current Survey directory and that you select when requested to amend or replace.
At this stage depending on your angular close which has been determined by your field readings you may want to adjust the bearings before you run the Bowditch adjustment. In our example you have a misclose of only 5"
In your calc book, paste in two copies of the initial misclose.
On the second copy adjust your bearings by writing the adjusted bearings in pen.
In the edit traverse window you can now overwrite the bearings with your adjusted bearings, Right click and [Calc Misclose] again
Print Traverse again. Use the "Append" option and not "Replace" when printing and paste in your calc book. Hopefully your misclose has been decreased. Do NOT tick the "Print Adjusted Dimensions Box"
Now it is time to apply the Bowditch adjustment by Right Click and choose the option
Note the the bearings and distances displayed, your raw traverse remain displayed unchanged however adjusted points have been written to the main file and show on the main screen.
To print the adjusted bearings and distances right click and tick the "Print Adjusted Dimensions box". Print, Append and Paste in Calc book.
Close the edit Traverse screen and return to main screen.
Here you will find your loop traverse adjusted and joined by a traverse string.
If you require a certain traverse line orientated to a fixed starting azimuth ie "X"-"Y", you can rotate around your initial known point. In this case swing your job +0?00'02" around Point 1
Select on the Tool Bar
Select , the default is All Points, All Layers which is fine if you have only traverse points in your file. If you have other existing points in the file you will have to select the range of new traverse points.
Select tick box
Key in the rotation angle +0?.00'02"
Key in rotation point, Point 1
Check that you have rotated your traverse correctly so the "X-Y" starting azimuth in our case is 0?00'00"
To adjust a traverse between two fixed points, you must key in the two fixed points in your job before you start and proceed as above.
