I'm trying to incorporate breaklines along canals and unlined rivers so that the elevation between the breaklines is filled based on the breaklines. I've tried to follow the concept that ESRI describes within the following help article: Incorporate breaklines with LiDAR. The article doesn't explain in detail the requirements of the feature class that will be used within the LiDAR to achieve the following.
The approach that I've used so far is to generate polylines that represent the location of the breaklines that I wish to use within my Terrain. I then used 3D Analyst tool: Interpolate Shape. to extract the elevation levels from the terrain. I then added the following to my Terrain as SFType : Hardline.
