Hi Everybody This thread is just a bit of fun. I’m not a complete SketchUp novice as I use it for my work, but this thread is different as I want to document my attempt to create an accurate ‘fully working’’ model of my old motorcycle engine, using just native SketchUp tools and no plugins I boug…

@TDahl Thank you very much for your post. I really enjoyed reading the thread you linked to and I hope to study your project a lot more going forward. I can see that it’s a labour of love for you and the results I have seen of your work are incredible. I used to work on military aircraft in the ea…

@jean_lemire_1 @endlessfix @db11 @SketchUp3D_de @tweenulzeven Thanks for your responses - in hindsight I may have been a bit naïve thinking I can do this without plugins and I will definitely check out any that are suggested :+1: I can already see one of the trickiest parts will be animating the c…

Looks like a good project. If I might make a suggestion, my recommendation would be to use meters as the set modeling units whether you are working with inches or millimeters. This will allow you to create the small details you’ll need.That’s my go to method unless I’m modeling one small part for so…

[image] kevin58: Also, did I read somewhere that you are happy to share your model? If so, I would love to study it in its full detail on my machine. Hi Kevin, yes my work-in-progress model is freely available via this DropBox link . Note that it is about 260MB (in pre-2021 uncompressed format…

[image] kevin58: I’ve been studying the Fredo6 Animator which is fantastic (and it can produce 4K video at 60fps) but it cannot animate that connecting rod movement You may be surprised what can be accomplished with @Fredo6 ’s Animator. I’ve used it a lot. The tricky part for complex motion (b…

That’s interesting - I studied some tutorials earlier and couldn’t see how Animator could work for the connecting rods. I then spent some time experimenting with the method shown by @DaveR to reproduce the motion of the connecting rods although I used Outliner rather than Tags to hide the multiple i…

[image] kevin58: I used Outliner rather than Tags to hide the multiple instances. I find that method is generally not the best way to do this. It can make file management more difficult especially as your model’s complexity increases.

@TDahl I downloaded your model and I’ve just spent a good while looking around it. I just kept selecting individual components to study in isolation as your attention to detail is so spot on. All I can say is WOW ! That is an amazing achievement and I take my hat off to you. :clap: :clap: …

I think Animator could be used to do a pretty good approximation of the combined up-down translation and back-forth rotation. Use the “easing” feature (I think that’s the term in Animator) to make the motions non-linear, giving them accelerations at the start and end corresponding to the harmonic mo…

Thanks Dave - I will definitely do that.
