Terrain contours
Show terrain contours and choose their elevation interval.
Contour Line OverlayContours displays lines of equal elevation over the available terrain. The interval controls the elevation difference between adjacent levels. Contours help you read a model; their smoothness and density do not improve the accuracy of the source data.
Show contours
Open the top-bar Display menu and turn on Contours. This changes the view rather than the terrain elevations. Other overlays can remain on independently.
Set the interval
Expand the control beside Contours to reveal Interval. Choose a spacing appropriate to the height variation you need to inspect. The control uses the project unit system, so the displayed value follows metric or imperial settings.
Read and hide the overlay
Closely spaced lines indicate a steeper change than widely spaced lines at the same interval. Check the underlying imported data before using the result as a measured survey. Turn Contours off to hide the lines; this also closes its interval control.
