3DClipper

From Fmepedia

This transformer works the same way as the original Clipper, however, it takes into account z coordinates of the clippees and drapes clippers onto them.

In case of the regular Clipper when both clippers and clippees are 3D, some of the clippee vertices sometimes get elevations from the clippers. This may be fixed on the core level in the future.

To show the difference between Clipper and 3DClipper, there is another custom transformer included into the workspace example - CoordinateSwitcher, which switches Y and Z coordinates, showing the front view of the features. Red on the front view on the screenshot shows Clipper results, whereas green shows how 3DClipper works.
