When you have a TIN model a breakline shows a break in slope. They will always form the edge of a triangle; a triangle and a breakline would never intersect. With a 3dLine it is not necessarily a break in surface. Therefore a 3dLine and triangle could intersect. If you've not specified a difference in your captured data then I don't think the difference is vital - but if you can pass break lines in a separate port you'll get a better surface model. I think this info is in the help under the Factories and Functions manual. If you can't find what you need in the transformer help you should look up the factory underlying the transformer. If often has a bit more detailed information. Hope this helps Mark Mark Ireland, Senior Product Specialist Safe Software Inc.
