Feature to Follow
There are two working options, depending on the chosen feature:
Point - The program calculates the difference in the z-value of the chosen feature and the input feature.
Surface - The program moves the origo of the extrude from the input feature to the triangulated surface which is below the input feature. This only works if there is a surface right below the input feature.
It is also possible to move the extrude origo to the lowest surface point under the feature by using the Extrude to Lowest Surface Point.
