COGO Dialog Common Buttons

COGO dialogs use common buttons. Learning what these buttons do can help you use the dialogs efficiently.

Save, Compute

Many of the COGO commands display a dialog where you tell TPC what you want to do. They will include a Save button if the COGO command creates or updates a survey point or a Compute button if the command creates survey data like points and traverses. Most dialogs remain open after you Save or Compute, so you can check your data, Undo the COGO command or repeat the command with additional data.  Since the views are synchronized automatically, you will usually see the changes you made to the survey right away. Take a look at the data and see if you got what you expected.


If you choose Save or Compute from a COGO dialog and don't get what you expected, choose Undo and start over. As a rule, TPC removes any points and traverses that were created and puts you right back where you started. You can even close the COGO dialog, check some of the computed points, then re-open the dialog and choose Undo.

See Undo GOGO Save and Undo COGO Compute.


Many COGO dialogs perform their computations as you enter data. Once the dialog has enough data, it actually computes the points and intermediate data associated with the dialog. We refer to these as the automatic computations of the dialog. As a rule, these dialogs include a Recompute button.  Think of it as a peace of mind button.  You don't have to use it. But if you do press this button, TPC repeats the last automatic computation for the dialog.

Remember, you still need to Save the point to update the survey.


Most dialogs include a Summary button. Choose this to record the COGO command's data and results to the active Report. Each summary starts with a section in double brackets [[ ]] showing the name of the COGO routine. You'll also find information on the distance and direction types used, a recap of the data used for the computations and any computed points resulting from the dialog.


Other dialogs include a View button. Choose this button to draw a picture of the solution in Drawing View. TPC replaces the current drawing with a temporary drawing showing the COGO results including point labels and line labels. It's a great way to identify which intersection point you want to make sure you got the end of the line you wanted. Click the View button again to close the temporary drawing and return to the one you were working on.


This button clears the input fields and any intermediate computations in the dialog. Use it to start over with a whole new computation.

Show Options

This button expands the COGO dialog, allowing you to select the distance type, distance units and direction type used by the dialog.

Protected Points

Some COGO dialogs allow you to choose whether or not to modify protected points. If you do not see this button, protected points will NOT be modified.
