When using the Tin Interpolation tool. There is an option to identify a layer as Point, Structure Line or Break line. However, when creating a TIN comprised of a point layer and a Structure line or Break line layer the resulting TIN is inconsistent in holding the Structure or Break line. Example: Road edges (AP-Purple), Road Crown (AC-Purple), Ground Break (GBRK-White), and Ditch (DTCH-Yellow) are all break lines. AS you can see in the sample image where you can see a purple line, the TIN did not hold to the break line.
