ArchiTerra uses a simple object to represent the contour lines.
Nobody never asked for this issue but it makes sense!
So the faster and easier way could be the following:
1. Calculate the existing contour lines on the existing terrain
2. ArchiTerra calculates and inserts the Contour Lines object
3. Select this object and save it as Library Part: very important save it as binary
4. insert this object that represents a "snap-shot" of the existing situation
5. use the "normal" ArchiTerra feature to calculate/represent the contour lines in the modified terrain
