Build the Perfect Crank-Slider Mechanism with Onshape and Revolute Mates! 

This guy never misses, always great videos. Thanks!

Clear and concise, thankyou

Your construction techniques really appeal to me, because they focus a LOT on how to get back to extruding/projecting and drawing constrained parametric objects/parts from the raw orthographic (or even just ONE primary orthographic) projection of the mechanical drawing. I like that a LOT, as it gets back to describing a minimal amount of sketches necessary to create the drawing (possibly incomplete for recreating from scratch as some dimensions are in the extrude lengths/offsets, but still, very fast and quick). It also blows my mind to NOT let the physical placement in 3D space get too much in the way of your creation of a part, since you can easily CHANGE that in the assembly. For example, you construct the crank part on the OUTSIDE of the connecting rod, even though you plan to eventually go back and PLACE it on the inside. That is just a detail that is sometimes hard for me to not obsess about.

hey, thank you for this video. As part of my major at school, I am going to use it for my project. I mean that I will print this modeling and have to actually make it move for real, with a motor servo. How do you recommend me to do it? I have nowhere to put it

Thanks

Here is a link to the file: cad.onshape.com/documents/2f917a93090a98dd44db1966/w/20a9fc2ced5ca64bf3266b3e/e/a84bc190dbcfcb5610da42c4?renderMode=0&uiState=644674a4171042409c0df877

Thanks for the video. Nice and clear and easy to follow what you were doing. Unfortunately life in Newbie World is never as simple as in Teacher World. Having followed your Mate choice and fitting exactly (Three cheers for the K key) my drawing ended up with a whole host of Mate errors. In every case the error message is 'Mate over-defines assembly'. There are only two implicit mates in each connection. Where possible I have trided to get the Z axis the same in both cases or facing each other if not. Do I need to go back and do some constraint killing in the Part Studio? The early 2024 version of OnS certainly provides auto constraints by the bucket load.

+Edit+ two minutes in desining i realized where i screwed up, gotta make it 360deg rotate on the crank side. NP make it high enough it

Thank you! I was only looking for mating tips, but you also taught me dozens of other things in just how to manage construction and keyboard shortcuts. Thanks again!

Thank you That was really Helpful

정말 감사합니다.
