For anyone this is a part two of the whosa post to do road kerbs. A similar request now solved.
To whosa how many more questions are you really going to ask for ? This is standard day to day field survey stuff. The best solution is go back to the original data it will be some form of XYZ file hopefully it also has codes as well. Post that then we can really see how we can help.
For Lrm like the other post the "point",s are the correct part to join not the mtext, so pick inside and do some form of ray trace angle to sort the join order, its easy for a rectang or always convex shape draw a "H" of points to test.
This is from field survey auto strung, blocks added. This is what whosa wants. There are many answers out there start with Civ3D.
