Import Compass Data

Create Plot File in Compass

First you must create a Plot file with Compass, so that Breakout can use the station positions calculated by Compass loop closure.

Compass seems this file automatically when you click Process and View Cave:

Process and View Cave

If for whatever Compass doesn't save a .plt file with the same name as your .mak project file, you can create a .plt file by going to File > Save Plot File... in the viewer:

Save Plot File

Import data into Breakout

Now in Breakout, go to File > Import > Import Compass data...

Import Compass menu

Breakout will ask you to select the files to import. Select both your .mak project file and the .plt file saved in the last step. (To select the second file, hold Ctrl and click on Windows/Linux or ⌘ and click on Mac OS):

Select Compass files

Click OK. Breakout will show a progress bar while reading the Walls files. Once it is done, the a results dialog will appear, showing any errors and warnings about the imported data.

You can click the Data tab to see the shots Breakout imported:

It's also good to verify that station positions were imported by selecting the NEV option in the Data tab. Any stations for which the Northing, Easting, and Elevation columns are blank will have their position computed by Breakout using very basic calculations without loop closure.

Import Walls NEV

If you are satisfied with the imported data, click Add to Current Project. You will see a progress bar at the top of the window that indicates it is parsing the survey data and creating the 3D model. Once it is finished, if everything goes well, the data should appear in the 3D view.

Save Breakout File

If you save the imported data in Breakout's format, it will be easier to reopen next time you launch the program. Go to File > Save and choose a file in the Save dialog. This file will then appear in the File > Recent Files list for quick access.
