Anton,
For the slope pattern creation:
Does it matter what line is input as “top” and what is input as “bottom”? I know in the problem that was posted here: Slope pattern between two feature lines
The polylines in the dwg alternated between which is top and bottom. The solution .dyn is able to take this into account. Does the node “SlopePattern.CreateSlopePattern” make this differentiation as well? Or will it only work when there is a single discrete “top” and single discrete “bottom”?
