Creating a Smart Line

Smart line can be used to create lines that track along edges of data.

Different data causes smart line to behave differently. When tracking along triangulations, the line tends to track along the intersection of near horizontal and near vertical facets, which is useful when extracting toes and crests. For coloured scan data, the smart line tracks coloured edges and extracts geological boundaries (if scans are coloured uniformly, this feature is disabled).

An improved feature of smart line now provides a preview of the smart line section before you click and create the section. Simply move the cursor around to see a preview line showing where the smart line function would  follow.

Note:  On scans with photographic data , it is possible to use the photographic data to create smart lines with greater detail. See Create an image tracking smart line below for instructions.

1. On the Create ribbon tab navigate to the Draw group. From the Line drop-down list select Smart Line.

   
   

Clearing Smart tracking disables smart line (the tool will function the same as Line).
