Ondrej,

You can use this email address to send questions about Compass. You can also
join the Compass User's group:

If you send your questions to the Compass Users Group, other people will
benefit from the discussion and you may get ideas and suggestions from other
people that I didn't think of. There is also an archive of questions and
answers that you may find useful.

Compass consists of several programs. Each program has its own independent
settings for units such as Meters vs. Feet. In the Project Manager, select
the "Options" then "Settings" items from the menu bar. On the "General
Options" page you will find the "Default Units" option, which gives a choice
of either Meters or Feet. This will set the default units for the Project
Manager. There are also options in the various statistics displays that
allow you to override the default in case you want to take a quick look at
the data in a different unit. If you wish to retain these settings so that
the program automatically defaults to these units, select the "Options" then
"Save User Settings" item. This causes the currently saved settings to
become the default settings whenever the program is run.

In the Editor, the units are set on a survey-by-survey basis. This means
that you can have a survey file with both Feet and Meters as the units
depending on how each survey was done. To set the units for the survey you
are currently editing, select the "Options" then "Survey Settings" item from
the menu bar. On the second page you will find the units settings for the
current survey. If you want to use these settings as the default for
subsequent surveys, use the "Options" then the "Save Default User Settings".
This will cause all newly created surveys to use these defaults.

In the Viewer, the Units option can be found under "Preferences" then
"Settings". Again, if you choose the "Options" then "Save User Settings",
the current units will become the default whenever the program is run.

These options are set in the Viewer. First, you need to have the Viewer
display passages. You do this by selecting the "Display" then "Show Passage
Walls" option from the menu bar. This will show the passages in whatever
mode is currently active, which is usually the simplest form. To change to
the more complex modes like Spline Mode, select the "Preferences" then
"Passage Wall Modeling" option from the menu bar. The options you want are
on the first page. Other passage wall options can be found on other pages.

I hope I have answered your questions. If you any other questions, feel free
to write.
