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

@Rich-O-Brien thank you. I don't know. It hink I'd be disappointed in the results.

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.

@Rich-O-Brien Good nooz. Nice to know you are happy with the next step. [image: 1756660920087-4-1000s-2081-x-1160-33911-tri-51s-gpu-resized.png]

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.

Hey mgash, What version of Rayscaper did you download? We only support SketchUp 2025 since version 0.9.44 and higher. [1] Regards, Thomas [1] Refer to https://rayscaper.com/faq/installation/#method-2-via-the-sketchup-extension-manager on how to check your version number.

@fredo6 [image: 1756395729559-8b00c38d-32b1-4d16-a882-a9ad57aca4ba-image.png] you can see my version now is v4.5a I just created one 36 seconds video and choose 0.75 with 45p/s I finally get 1 minute and 26second video: [image: 1756395848208-21dd5d35-3b7a-4912-b400-05ac27aac989-image.png] [image: 1756395882932-8ac1d9ea-d8e0-4762-8367-d9c1396fe406-image.png]
