When creating a legend table using the Group Table command, you can add a column that will display either the symbol or the survey line in the one column (Symbol/Linework type).

The Survey String Settings are used to determine whether to draw the survey line or point block in the column.
A symbol will be displayed in the Line/Symbol column if:
- There is a matching code in the Point Code Set (so a point style block can be assigned), and
- The code is either not in the Survey Line Set table or, if present, both 2D Linework and 3D Linework is unticked
A survey line will be displayed in the Line/Symbol column if:
- There is a matching code in the Survey Line table, and
- Either 2D Polyline or 3D Polyline is ticked on to create a Survey String
