3dpolyline Triangle with 4 vertices

[pyou]

Hi all

 

I have many  Closed 3dpolyline Triangles with 4 vertices each. Would it be possible with the help of lisp command to track all triangles and remove duplicates, please? Its the first and second vertices with same position.

 

Thank you

OVERKILL should remove the duplicate vertices.

not in this case , unless i am  doing something wrong. I have attached example dwg.

Basically i had 3DFaces as Triangles and converted them using lisp into  3dpolyline Triangles, but it creates 4 Vertices for each Triangle, another lisp which supposed to create contours over triangles refusing to do so and say 3dpolylines are not closed polylines.

 

Long story short, I am looking for a lisp which could create Contours at desired interval over 3DFaces. For example at 0.2m 1.0m interval and label them up along at specific distance.
