1. In the Display tab of the Map View, scroll down to the Contours section, click Show Contours to open and display the contours on the map.
2. Define the following settings:
   • Labels: Enable labels displaying the highlighted, custom or all contour values.
     • Select the font type and size of the labels.
   • Background: Select the background colour for the labels.
   • Fill contours
   • Horizon/Surface Group: Select the horizon or surface group on which the contours will be displayed.

• Property: Select the horizon property/surface group that will be contoured including displaying contours in TVDSS (ft).
• Value: Type the starting benchmark value of the contour for the lowest point on the structure. For example, if you enter a value of "5", and the lowest point on the structure is 3,500, you will see the lowest contour displayed at 3,505 on the map, followed by the next contour at the specified interval.
• Interval: Type the interval value between contours. If you wish to display only ONE contour value, type the desired Value and set the Interval to 0.
• Highlight: Type a contour value which you want to highlight on the map. You can also enter multiple values separated by comma (i.e. 1000, 1200, 1400), and/or a sequence of numbers in a min-max[step] format (i.e. 2700.0–2800.0[10.0]). For example: 1100, 1275, 1300–1400[50] will highlight the contours for five separate values. Highlighted contour values that are different from the contours captured by the Interval will be added to the Map View.
• Lines: Click the colour box to select a colour for the contours. Type the line thickness for the contours or click the up/down arrow to increase/decrease the contour line thickness.
• Highlights: Click the colour box to select a colour to highlight the contours defined in the Highlight box. Type the line thickness or click the up/down arrow to increase/decrease the line thickness of the highlighted contour.
• Create Polygons from Contours: Generate polygon objects for each horizon contour value that has closed contour shapes (see Creating Polygons from Contours).
• Minimum polygon area: Enter the minimum area for the polygons to be created.
• Export Contours: Export the contour as a shape file (*.shp) or Kml/Kmz file. Note: Needs project CRS to enable export option.
