Position:
You can set the left and right position of the log column in selected units. The
default unit displayed is the one set for the Ruler Bar (see 1.3.2.4 Positioning Logs).
The total width of the log given through the Position values is subdivided to display
the strata columns according to their relative width.
Contact Dictionary:
The top and bottom boundaries of each box in a strata column are graphically
presented as straight lines. To present the box limits in a more significant manner to
reflect i.e. major/minor tops or unconformities a Contact Dictionary can be
designed or loaded. Refer to 1.5.3 Using Contact Styles for more details.

Strata Dictionary:
The text displayed in a strata box can either be a string typed in from the user or it
can be text picked from a library along with a pattern or color fill for the box
background. These library file are the same as the ones for the Lithology Log and
carry the extension *.LTH. Remember that within LithCAD you can create whatever
pattern you want. The text displayed in the strata box is the code set for a pattern.
Refer to the LithCAD User’s Guide to learn how to create patterns and libraries.
