The following idea is related to the survey tool gap analysis that is already being considered.

The Extract Contour tool should be enhanced to place a graphic line at a specific elevation. Currently, you have to change the contour interval of my terrain to my specific elevation, display contours, then use the extract contour tool to place that graphic of what ever is displayed. It would help production if the user was able to input the desired elevation into the tool to extract, that way the user doesn't have to change any settings for the terrain attributes.
