Smooth the polylines of the imported terrain contours

When importing terrain, the contour polylines that are created, might appear with sharp edges.

This is attributed to the contours being created based on the grid of elevation points that are imported. Therefore, the grid dictates the sharp contour edges.

If you wish to smooth out the contour polylines, simply follow the steps provided below:
