Schemes provide a way to load drawing properties based on a keyword or range value defined in the imported data. For example, a lithology log uses lithology schemes. The lithology scheme contains keywords, such as granite, clay, etc. Each of these keywords is assigned a fill pattern, contact line properties, line properties, and text properties. Schemes can be reused; therefore, you do not have to go through the time-consuming process of assigning the same properties each time you create a new log. Reusing template and scheme files is ideal for those who want to continue making the same looking borehole designs for a wide variety of borehole data. 

The Scheme Editor is where you link specific range values or keywords to display properties. In the example above, the lithology keyword “Granite” is tied to a granite fill pattern and other specific display properties. When the scheme is assigned to a lithology log, every time the word "Granite" is used in the database table field, Strater uses the properties assigned in the scheme in the graphical borehole display.
