 Creating a TIN mesh including breaklines is significantly faster then incorporating

Project Polyline to TIN initially create the same results. However the
resulting line in the mesh will only be a geometric object and not act as a
breakline during e.g. decimation.
3.4 Decimating a TIN Mesh
A mesh created from pointclouds usually contains a high number of triangles. When the
deliverable is a triangulation in another CAD package, it is normally required to reduce this
number.
 Prior to actually creating the mesh, a pointcloud can be reduced in number using
the command Edit Object

Cyclone supports mesh decimation by which the number of triangles in a mesh is reduced
according to user-defined parameters. The Decimate Mesh dialog supports interactive
decimation. To see how this is done, best view the mesh in wireframe mode.
