Create Cleaner Contours

One of the strengths of OCAD is the generation of smoothed contour lines.

With the latest Service Update, a combined method of TPI and 3D smoothing is used for the calculation, which leads to improved results. The file size also shrinks, because at the same time irrelevant contour vertices are removed and the contours are converted into B├ęzier curves.

In our example, the not smoothed contours appear brown. The smoothed contours according to the new method (blue) are cleaner and show the terrain more precisely than according to the old smoothing method (green).

How contour lines can be generated is described in detail in our Wiki.
