Exact Setting and Magnification

It is often useful to set an exact scale or rotation. For example, you may want to draw a map at exactly 100 meters per inch. COMPASS allows you to set any scale, rotation or magnification. Here is an image of the dialog box that sets these parameters.

Vertical Magnification

The Viewer has the ability to vertically magnify the plot. With vertical magnification, the vertical aspect of the plot is magnified while the other dimensions remain the same. This accentuates the vertical features and it is useful when you are working with a relatively flat cave. Increasing the vertical magnification allows you to see the subtle vertical features in the cave.

This image shows two profile views of Groaning Cave. The top view has been vertically magnified three times. Although the cave appears to be relatively flat, it is actually developed along several slightly tilted fault blocks. These show up nicely with vertical magnification.
