Creo Parametric - Top Down Design and Mechanisms

[@salmaelmarzouki9946]

Hello, do you have videos step by step of how to make this airplane using creo, please ? I have been having trouble making this particular design, I hope you have a video(s) to follow it to make one like this

[@CADPLMGuy]

I do not. This is an AH-64 Apache helicopter.

Thank you, your videos inspired me to pick up kindle versions of some of your books. What's the point of doing this with skeletons if you have to do the same thing with your parts in an assembly where those parts were created from features in the skeleton. - wouldn't you be doing the work twice?

[@CADPLMGuy]

I don’t understand your question. Why would you do the same work twice?

[@plastibob]

@@CADPLMGuy Your showing skeletons, what if I create an assembly and I create the same non-skeleton parts (from the skeleton geometry) I don't understand how you could assembly the parts into the new assembly with adding the same connections - unless I'm missing how the skeleton connections can carry over?

[@CADPLMGuy]

You are not going to assemble the components based on Skeletons with connections. The assembly connections control the motion. The components are typically assembled using the Default constraint. If you have trouble visualizing this, try applying the concepts to a simple four-bar linkage assembly.

@@CADPLMGuy Thanks I will try, so if I understand you correctly if I create a Creo part “rotor” based on your “rotor” skeleton and assemble it to default I should be to spin it using the mechanism drag hand? Update: the only way I got things to work is to create the various skeletons assembled with mechanism connections, and then in the same assembly, assembled each part to the appropriate skeleton with constraints.

Amazing work

Thank you! Cheers!

You gloss over quite a lot in this tutorial 1. How do you create a skeleton part, outside of the assembly environment?

[@CADPLMGuy]

What did I gloss over? You can't create Skeletons outside of the assembly environment. I have two other videos on Skeleton creation. I also have a Tips and Tricks video that shows how to convert a standard part into a Skeleton. But if you look at the title of this video, it specifically covers Top Down Design and Mechanisms. If you are interested in more information about Skeletons... I suggest you watch one of my videos on Skeletons.
