How do I plot this beam, given the coordinates, distances between the nodes, and the connections, and the lengths of each segment?

This is the beam that I'm trying to get a figure out off, and I was wondering if there are any ideas that could help me plot. Below is the wanted end results.

Read about delaunayTriangulation. This would be easy to use to plot the shown.

If not share the data you have.

[Sammy Patwary]

here is my entire code, for it i tried using the method but got a slanted version of the beam

[KSSV]

You might be plotting the deformed beam. Try plotting the initial beam before analysis.

[Sammy Patwary]

to be honest i kinda dont know which is the initial beam

[Sammy Patwary]

but that makes sense
