Dude, showing me McMaster-Carr saved me weeks of unnecessary work. I'll also need the chain trick of course. Thank you!
There is a (very expensive) product called "Working Model" which does a nice job of modelling components so they are constrained not to intersect. It also can attribute "real world" properties like density, gravity, elasticity, etc. It includes "motors" and linear actuators to activate the models and strain measuring connections. A lot of fun to play with. I once made a couple hundred unit bead chain and let it fall under the influence of gravity; now that was computation intensive. It slowed my old 80386 to a crawl.
This Topic deserves a revisit!!
John thanks for doing these videos. I downloaded the trial version of Fusion 360 two weeks ago and have been playing with it and watching yours and Autodesk's videos. I watched your webinar on CAM for the lathe and was able to sketch, model, Cad, post and machine my first part on our Haas TL lathe at work thanks to you, and your inspiration.😀👍🏻
Just dipped my feet into cad two days ago and im already hooked. I modeled the basic design of an invention idea i have. Such a powerful program. Thanks for all your work
Hey.. did you ever finished that invention you had in mind?
@@oreoflores7204 Its actually in final prototyping. I've got a small team put together and I'll hopefully be sourcing investment capital within a year or so!
That tip about using McMaster catalogue in web browser instead of fusion was priceless!!!
Thank you!!
The tiny McMaster browser in fusion sucks!!
It's also brilliant because there's no way to copy a part number *out* of the tiny browser
the C key is not for sketch its for circle the same thing will happen if you hit R for rectangle and you're not in a sketch already
Interesting approach - I'm working on a pulley set w/ timing belts, and was considering drawing the profile of the closed belt, then extruding it. While that would produce a static model, it wouldn't have the dynamic side. Great video!
Try turning off capture history if you don't want things to be captured in the timeline. You might be able to make a external chain component with the capture history off, and still keep it on in your main design.
You can also download a McMaster part to your desktop and import it to Fusion 360 from there. This comes in handy if you have multiple parts that you will be importing at different times. Having them ready to import on your desktop is a convenient way to save time.
If you notice the data for separate bodies was there even though Fusion thinks it's only one. For a simple part like this no big deal but you don't want to dissect complex parts. I found that if I strategically split bodies Fusion realizes all the individual part-bodies magically. Then I just combine anything I unintentionally split.
+NYC CNC I tested this with the chain. 4 moves and done a360.co/1Nw7VeX
Super helpful even until today using the latest version. Thanks!
what you are doing is the chain has the same width each other parts to join together instead of wider and narrower each other to join together
Thank you for strait forward, well done tutorials. I just started with Fusion 360 last week, you solved 3 problems for me today!
It can not be done with joints, The way to do it is with "enable all contact".
I had no idea it was so easy to import from a part number!
Going off the rails on the crazy chain.
I have learnt a lot for your video. I have been trying to sketch a sprocket 60chain 50teeth for stock for weeks. If I had seen your video earlier, I could have saved weeks of spinning around.
THERE SHOULD BE A PATH CONSTRAINT WHEN IT COMES TO GEARS AND CHAIN INTERACTIONS. BY THE WAY, FUSION 360 IS A PRODUCT OF THE FUTURE THAT NOBODY CAN MATCHED!
Second sprocket w/grounded shaft, (and) longer chain length, and contact sets and/or motion links?
Or you can always throw more CPU at a problem.
+NYC CNC Ugh, I tried it and rapidly realized that Fusion 360 needs better kinematic solving. They have Reactor (with Havok plugins) for 3ds Max, and *really* need to bring it over to Fusion. A chain drive limited to 8 links and two sprockets isn't very useful: Contact sets of just the two sprockets and 20 chain rollers still causes 360 to choke and freak out. Meanwhile, games using Havok can have a tank drive through a brick wall and have it look realistic.
@@bobthecannibal1 And, got any progess? I mean games probably dont use the overgeneral approach of contact planes, but simple high level classes "this is a gear and this is a chain and they like each other".
@@bobthecannibal1 Game engines work with polys for both visible geometry and collision. Fusion works with nurbs. This might make Havok and other physics engines completely incompatible.
to fix your timeline issue you slide the bar to the point you want then click and select "delete after this position" or something along those lines lol.
it's a handy feature!
+NYC CNC Wouldn't work. It would do the same as deleting them one by one from the right in effect bringing back the deleted bodies (because you are deleting the deleting of the bodies - if that makes any sense). On top of that you are trying to delete actions in between two actions and preserve the last one - in this case the push/pull you used to cut the pin out. I think you did it the only way possible.

i just checked on one of my models, was in bed catching up on cnc vids when i wrote that.
slide the history marker to where you want on a selected component then right click on any of the grayed out icons/operations and select 'delete all features after history marker'
Nice video btw. I like using fusion 360.
Thanks for making these videos, fantastic.
you only used the outer link of the chain when you made yours there are 2 different links in a chain can can see the difference from yours to the unmodified one
Hey, you can do a motion link to give this the appropriate kinematics in Fusion 360.
Could you do that? I have the same problem
great video guys
Good Stuff, Thanks!
Not sure if this would work, and it's another cheat for sure. Make a plate with a slot for the chain path, parallel to the chain. Then you could use the pin and slot joint for the chain pins. Last hide the plate or maybe make it construction geometry.
after pasting the second bead chain, and joining them, isnt it faster to do a mirror?, and then a mirror of a mirror?, or even a pattern?, it will make the joints works?
HOW TO create a cable(wire) on pulley and link motion in fusion 360?
Same thing,you solved it ?
It has the product detail right next to where you just copied it from like, that had me in stitches lmao 😂 one you find your part click it and and then top left of box is prouct details !!
Is the insert for McMaster carr all ready in the software or is it something you add?
+NYC CNC Very Nice!
Thanks for the video but it won't let me delete parts of the chain. The selected faces could not be deleted.
Ensure that faces are only selected from a single body, and that no duplicate or invalid geometry is included in the selection.
Have you found a way to automatically replicated the links to make any chain length without having to manually duplicate the links?
John I am not sure as I have no real experience with chains but would the "Contact Set" function work for this purpose?
And by this purpose I mean allowing the chain to move between two sprockets*
+Clayton Spangenberg Good idea Clayton, this is how I would do it in Inventor, I haven't used Fusion's contact set function though - I didn't realise they had contact sets in Fusion actually, but it looks like the function has been there for a while.
I just finished the vid and saw John tried contact sets - I don;t remember them being so processor intensive in Inventor, not sure what is going on there. Mind you, I never used them to model chain and sprocket, there is a bit going in in that simulation.
Clayton Spangenberg I tried using them for a screw and my (decent) computer froze Fusion when I moved it.
@@alphgeek inventor is just much more efficient, does not crash nearly as much as fusion. It is it's bigger brother after all.
the chain has a wider and narrower intervals each other, you are editing in a wrong way, you should take back the original chain part
S P R O C K E T
hmm seems tedious to have to copy and join every link you need. Would be nice if there was a pattern type command to do this type of work for you
I'm kinda late to the party, but here in 2018 there is a pattern called rectangular pattern that if you ignore the 2nd dimension lets you repeat bodies (not sure about components) in a straight line.
Did anybody mention already that the chain has now only inner links?
you are doing the wrong chain, supposed to be the chain has a wider and narrower intervals, what you are doing is that in actual real chain it does not move
please upload a video on chain and sprocket motion study
John go back to where you imported chain look at the chain you removed the bearing plain of chain, the single plain chain that you used after that point would not work.that might have been why you had problem with modeling .
7:14
Is it possible to make it unique afterwards?
So the same end result as you have, but afterwards when I have copied all of those.
Just cut the link.
how to model timing belt in fusion 360??? i'm trying to model the belt path of a corexy 3D printer (gt2 belt)
I have got a question, Can we convert this imported cad to drawing sketch???
Can you model a simple, flat flange with a 60 degree bevel, and generate Gcode for a 5 axis waterjet? I am not familiar with Fusion360 at all. Is this possible? Thank you.
Y si quiero utilizar la cadena para mover 2 engranajes? ( como Conjunto)
Help please
John I think if you use mcmaster add link #6261K243 and then you design the boy link to go with it your copy will work OK or not, 360 will do so much but some times it's hard to find .
Will the same problem arise with belts/pulleys? Don't think F360 really has a good system for either.
+NYC CNC I guess I am just asking if there is a way to use belts/pulleys with the teeth and everything. I assume it would have the same limitations as the gears and chains.
how i can get the 3d from McMastercar model in SolidWorks?
Here is a video of a working roller chain in Fusion 360: ruclips.net/video/F-mAVhdW8z8/видео.html
Dear respected sir, hope you are in good health with success and happiness. I'm really happy for your good work.
Now I'm trying to design a timing belt pulleys for my CNC machine. But facing some problem. Please could you help me?
I've done physical design but how to rotate or behave it in real world?
This is how SW does it: ruclips.net/video/orqr5ZhObsU/видео.html
Chain and belt mate is different (the chain / belt doesn't appear to move but the sprockets and gears are synchronised) but it's rather like cosmetic threads - why use all that computing power just for visuals?
Fusion 360 and Onshape haven't implemented chain and belt mates yet AFAIK but they are very powerful if you want to "fit" a std belt length and then set the shaft and tensioner positions. I've done this with toothed belts on my CNC machine so I can use a tensioner wheel rather than slotting all the holes and sliding the whole stepper motor to adjust the belt.
I'll C for Cketch???? I had to rewind that and laugh my ass off as I probably would say the same dam thing ;)
Check this video here ruclips.net/video/VbSkwvZyU_0/видео.html and skip to 53:42. It might add one more information about joining, I learned a lot from you, thanks :)
you should of done the chain in DM first then brought it in, if doing defeaturing you need to do it in DM
correct
+daniel lyall why? what he did was fine. It's neat being able to relegate a deleted face to a DM feature.
it's what all the ADSK vid's show on defeaturing, I know it was fine but the time line was a mess
daniel lyall i don't think it was a mess. The DM stuff wasn't even in the time line in the end.
+Scott Moyse 14 mins it was there then boom gone
+NYC CNC Interesting video, John! Most everything I know about Fusion360 I learned in your videos. With that being said I wanted to point out your impossible chain model, in that all of the links are fused together (no outer and inner link combo). So i thought i would try it myself on my fairly decent gaming pc with full contact sets. This is what i came up with if the link will work. a360.co/1XDXtYy I don't really know if i did any better but maybe we can all share what we have learned as a RUclips CAD community along with perhaps a better implementation of motion transfer by A360 and then be able to get some really cool mechanisms designed. In the mean time keep these videos coming, see you for the Wednesday Widget.
+NYC CNC It worked at first when I only had a few links around one sprocket but i could not get it to work around both sprockets. I would put the inner link in place on the sprocket with the align command ground it and then put the outer link on with the joint command so the chain was not actually connected to the sprocket. Once i had several in place i would enable all contact and ungroun everything. At first it would work so i continued to the end but then i could never get Fusion to use more than 15% cpu for the calculations and it would lock up.So maybe if you do download it you may be able to get a few links to work if you just delete some. :)
+NYC CNC Oops, looks like I missed where you said the links should be nested inside each other but wasn't the point of the video, the first time I watched it.
Contact sets?
If you import the chain first and shut off the timeline do the direct modeling (defeaturing) then turn the timeline back on and import the sprocket you will not have the issue of having to delete the parametric info that you had here. Note: I believe you will lose any parametric info if you don't do it first.
Here is a great video on sprockets an chains ruclips.net/video/G4ZsCWFlvNc/видео.html it's for Inventor but I think you will learn a thing or 2.
Not sure if you noticed but you hit 100,000 subs Congrats!!! Any plans of doing a video to acknowledge this milestone? Most Tubers get very excited over these things.
Keep pluggin away at it!
+Ed T except you lose all timeline stuff you created before that point.
Scott Moyse Yes this is true that is why I recomended doing it first or you could even do it in another document and then import/upload the results.
Ed T the latter is often the only feasible option if you don't want to do what John did. Hindsight is a beautiful thing...
Scott Moyse I would agree.
I'm a big fan and follower for a couple of years, but this video was neither about modelling nor about successful sprocket & chain successful joint... a bit bummed, I was really hoping to find some answers in this one.
Not your best demo... I like your channel though! ;)
First?
WHATTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT.
I AM SORRY SOLIDWORKS BUT IF YOU DONT INNOVATE FUSION 360 WILL BE OVER THE COMPANIES
COOL VIDEO AS ALWAYS JOHN
This was point blank a horrible video and a waste of time. Bumbljng, fumbling and whatever. Id be embarrassed if this is the quality I uploaded to the world, holy crud.
you should delete this video because you are making a failure of editing a chain that does not work at all, you are making tutorials in a wrong way, chain has a wider and narrower parts intervals to each other
