Sketchup diffusion seems to be so old fashioned. Google is the absolute winner! [image: 1756849137112-nano-falk3-resized.jpg]

OK, despite some issues I have gone ahead with a HQ render. A better setting with the seating area. too. [image: 1756831742566-1-hq-1000s-2081-x-1160-420129-tri-2m-42s-gpu-resized.png]

Try my suggestions of softening and hiding the edges. You could also consider radiused edges instead of the hard square edges you have.

@majid thank you. Are you referring to the animations I posted?

.blend to .skp is definitely needed. I’m gonna test this later this week as I’m curious on how you manage modifier stacks.

Very nice work Gus

@fastrerudy Have you installed Libfredo? https://sketchucation.com/pluginstore?pln=LibFredo6 It is required for the extensions you mention.

I am using the stiffness method per Ch. 15 of R.C. Hibbeler’s book, Structural Analysis. For intermediate loads between supports I use (FEM) fixed end moments. I’m actually still working on the matrix analysis piece. I’ve got point loads pretty much in place I’ve just got to implement distributed loads next. I suppose I could have it generate the entire polynomial for both shear and the moments since I am generating them for each applied load, it is probably just matter of using superposition on them as well. Here is a first look at the ability to switch between various load cases for the deflection graph: [image: 1756721460278-loadcases.gif]

Looks fantastic mate.

Yes..I sent him a message on the link you sent me..I will also contact Sketchup Thank you for the help

@Mike-Amos LOL

Thank you, mates, for your kind words. I know that there are plenty of spots to be developed and improved. But the goal was to show the process (at least partially) from a rough sketch on.

@rv1974 said in Rework of 12 year old model.: TS calls to ban a user just for being negative to his his work ( note: not him personally). Isn't it pathetic? Could you also post what TS posted and later deleted in my address? I say this with all honesty and no sarcasm. I think you need some professional help

Thank you. A friend of mine, working at the Tramway company is printing it for me.
