- How to 3D-Model a Trammel of Archimedes in Fusion 360 | 3D Print a Do-Nothing Machine
By the end of this video, you’ll know how to create a Trammel of Archimedes in Fusion 360. The Trammel of Archimedes is a mechanism that generates the shape of an ellipse.
Some have even coined the machines to be the “do-nothing machine” as their pretty pointless [pun intended] when they have a knob on the end. Usually, they have a pencil or knife attached to the end so one can draw, scribe, or cut an ellipse into a surface underneath.
These are great little projects for woodworking or 3D printing, and kids seem to love them, so I thought this would be a fun object to model in Fusion 360.

Hey bro can you give me Its file cause i need it for my project. If u can that will be a great help
Hi Kevin useless to repeat all the postive comments - I just agree. You are clearly best F360 instructor in this net. Please please continue your videos, its so helpful to understand this software. Thank you so much.
Thanks, rk57chat! I appreciate the kind words. I don't plan on stopping anytime soon.
Please don't hesitate to comment on any of my videos should you have any questions. Cheers, Kevin :)
Hands down, the best Fusion 360 model tutorials on CZcams.
There were several concepts I have always wanted to know or understand about fusion 360 that I learned from this one video. Thank you.
Thanks, schmots! I'm glad you enjoyed this one and learned a lot from it. Don't ever hesitate to comment questions. Cheers, Kevin :)
I know I'm a little late here on this design. Took a long time to get to this point in learning 360. I want to modify it as suggested and print it. Thank you Kev
I really don't understand how you don't have a lot more subscribers.
Thanks for your effort to teach us on very easy to understand way without pointing out how useless we are :)
Hi, michkanm. Thanks for the kind words! I appreciate you commenting, as that helps my videos reach more viewers! Cheers, Kevin :)
Thank Kevin for this great video, like all your other videos from elsewhere. It's with your videos that I'm learning Fusion 360. It's the best videos I've seen on the Internet because you get to the bottom of things and take the time to explain your actions. I will continue to watch your tutorials.
Hi, joël RICHARD-FOY. Glad to hear you're enjoying them and learning a lot! Don't hesitate to comment if you run into any roadblocks or have specific Fusion 360 questions.
Thanks for your support! Cheers, Kevin :)
Thank you very much, Kevin, your tutorials are the best! I began learning F360 with your "30 days" tutorials and keep getting something new with your upcoming videos.
Thanks, Sergey! I'm glad to hear you're still learning from my tutorials. I appreciate you taking the time to watch and comment. Cheers, Kevin :)
Excellent material. Loving these videos. Compared to other tutorial series, they seem perfectly paced, and very slick and easy follow. Thank you!!
Thanks, metzUK! I'm glad to hear you're enjoying them. Cheers, Kevin :)
beautiful! ...thank you very much!.....i will try to animate my design following your steps.....
Thanks a ton for this. Ever since I got a 3d printer, I've had a desire to understand mechanical designs. Your tutorials help so much.
Glad to hear that, Dean! What brand printer do you have?
Will definitely be printing this! Very cool. Thanks!
Thanks, Travis! Let me know how the print turns out. Cheers, Kevin :)
Clear and very useful! Thanks a lot!
Thanks, Paul! Glad you enjoyed this one. I appreciate you taking the time to watch and comment. Cheers, Kevin :)
I'm using F360 for the first time to create a specific part to 3D print. As an intermediate 3D modeler with a lot of experience with 3D printers, I'm pretty up to speed with a lot of the concepts used in CAD modeling. After 2-3 days into this project, I'm finding it much quicker and more informative to just watch one of your videos that seem like they would cover the F360 function that I'm struggling with rather than go onto the community forums and search for answers. Inevitably I learn a better way to approach something that I've already cobbled together and have restarted my project several times to fix things along the way. Thanks for putting up such concise and well-explained videos. I'm still watching at 1.75 or 2x speed (with liberal use of the pause button), but it's so nice not to have to click through all of the exposition that is present in so many of the other tutorial videos.
Also, It's turned out to be really helpful that there's been a UI refresh since you've posted some of your videos. Figuring out where some of those functions have been moved to helps me remember when to use them in my own project.
A great positive outcome from the change :)
The portion of the bar between the sliders is the hypotenuse of a triangle. The two sliders give sine/cosine of the angle described by the handle.
Best tutorials on YT. Thank You
Thanks, artineogda!
I printed this and it turned out pretty good. I used the settings Kevin suggested. Printed on a Anycubic Vyper.
I'm never going to print this but this showed me a lot of things in fusion 360 that I would like to learn.
I've been teaching myself F360 for the past couple of weeks using online tutorials. A lot of things are different in the new version of the software so it's been a challenge but I have always learned through experimentation.
Hi, POVadventure. In August there was a major UI update where they changed the location and terminology of several things. This video may help with how things have been restructured - czcams.com/video/tuZzHcmFtg4/video.html
Thanks for the useful tips Kevin
Thanks, Thistledoo 47603! I'm glad you enjoyed them. Cheers, Kevin :)

Great video. I am very interested in any tips on modelling for 3d printing. Keep up the great videos.
Thanks, Bernie. I'll definitely continue to do more tutorial videos geared towards 3D-printing with extra tips and tricks in there. Cheers, Kevin :)
Very nice work
Thanks, IceCreams62! I appreciate you taking the time to watch and comment. Cheers, Kevin :)
planning on machining it now from billet
As always very cool vid thanks ,.//., Iam learning so much,.//.,
Thanks, Karl! I appreciate you taking the time to watch and comment. I'm glad you're still learning lots. Cheers, Kevin :)
That is very useful!! Thank you. To attach a cuttingtool I think that there must be a kind of mechanism to keep the knife in the right direction, right?
Hi, Josef. Great question. The "manufactured" tremmel that I've seen in action had an attachment that allowed the knife to spin in 360 degrees. Then the knife blade naturally curved or spun around as you slowly pull it.
Would probably take some experimenting with 3D-printed parts. Cheers, Kevin :)
Great video and fantastic illustration. One question. I would like to make a wooden sign with cnc with several words/sentences and objects like an heart etc.. How can I combine these all together on one board in fusion?
Thanks, F. S.! I'm glad you enjoyed this video. In regards to your sign, you'll want to just be aware of how each additional piece (letter, heart, etc) is created as far as bodies and components. I'd recommend watching my video on the difference between bodies vs components - czcams.com/video/46UNmpQdbVc/video.html
You can simply create sketches of the letters and shapes on top of the wood board and then you can extrude them to your desired thickness.
One key thing to remember is to also label or rename each body or component as you create the parts. That will help you should you need to hide, delete, or copy parts. Cheers, Kevin :)
I am teaching myself Fusion 360, and stumbled upon your channel. You have a great way of teaching so that anyone can follow along. The only issue I am having is that my Fusion doesnt seem to follow along exactly the same way that yours does. I realize this is a fairly old video, and that is most likely the cause, but specifically when you are creating the arm portion, my fusion looks completely different. This is creating some confusion. I just realized that this is probably a pretty pointless comment as well, since i dont even really know what to ask to get a better understanding. First thing i guess is that when i create a different component and select it, all of my other components become almost invisible.
"First thing i guess is that when i create a different component and select it, all of my other components become almost invisible."
This is normal and a setting in your Preferences that you can change if you don't like it. It's mainly due to help you work on multi-part assemblies so you can see what parts of the design are active. Activate the top-level component in the Browser to see everything with full visibility.
Thanks again Keven Great Job! I think it would make more sense to me to use the z up as that is how our machines and printers work. Do you agree?
Thanks, Rich! I'm not sure what happened... I normally have the Z-axis up. I didn't even think about that or realize it until you mentioned... so thanks for pointing that out. I believe the default is still the Z-axis up and I agree that is the best for 3D printers. Cheers, Kevin :)
Commenting to boost!
cool thing made it after watching the video...thanks man
Thanks, Naveen! I'm glad you enjoyed this one! By "made" did you mean you 3D-printed it out or made it in Fusion 360? Cheers, Kevin :)
@@ProductDesignOnline just fusion 360 now... Will 3d print it soon enough...
@@liveonflow6976 Sounds good... let me know how the print comes out! :)
Great Video. Plan on printing one out tonight.
Why do we need to make a copy of the slider and then link them to the original? I'm not sure what this means. What happens during this process?
Thanks, Karen. Let me know how the print goes!
To answer your question - when you copy and paste a component you risk one getting altered in a different way than the others. When you insert a component or design file into a current design, you'll see that they are all linked back to that file. This way, the components will all remain exactly the same unless you decide to "break" the link and alter one. This Autodesk help article will explain this concept more in detail - knowledge.autodesk.com/support/fusion-360/learn-explore/caas/sfdcarticles/sfdcarticles/How-to-Insert-a-Component-into-the-Current-Design-in-Fusion-360.html
Cheers, Kevin :)
Great tip on the animate model as a whole!
But I have a question.. I try to make the animation in the animation workspace to output a video of the model moving but I can't do much in animation more than exploding components! and I can't do the animation of joints other than in the model workspace!
Hi, Ziad. Unfortunately, the Animation capabilities in Fusion 360 are still pretty limited. Here are some notes from the Autodesk site (this explains it better than I can off the top of my head):
The Animation workspace does not currently recognize joint constraints and will require you to move every piece individually. The idea to allow the Animation workspace to register joint constraints and animate them has been presented on the Fusion 360 Ideastation.
While the motion study will allow you to create a rendered animation (through the Render workspace), the joint motion is limited by the motion study definitions.
Another option could be to create a motion link between your joints and then create a screencast of you dragging the joints to show the motion in a video. This will not give as clean a video as the Animation or rendered motion study options, but it may allow you to animate your model without using a motion study or manually moving every piece in the Animation workspace.
In summary, if you do decide to do the Animation workspace, you would have to set it up to do piece by piece which would be pretty difficult with this Trammel design. Cheers, Kevin :)
@@ProductDesignOnline I guess we will have to wait to see some more advanced features in the animation workspace! Well, thanks alot for taking the time to reply and provide info. ❤
@@ziadammar3095 You're welcome! Cheers, Kevin :)
Why is every-time I start a new project the sketch panel isn't there at the top left? I always I have click on "create sketch" then select a plane for it to work. Also I noticed you use Z Axis as up. Might want to tell users to go into their preferences and tick the Z Axis Up box. Close the blank project and open a new one for it take a effect. It tripped me up when I started watching the 1st video. Great videos by the way!
Hi Jospeph. The sketch issue is a difference in the new vs old UI. As far as the "up" axis... I always use the default settings when recording tutorials. Changes listed here - bit.ly/defaultsettings
line drawing won't allow me to let go of the line and then type in the dimensions. I have to hold my finger down on the trackpad and type in the dimension with my left hand. Is this normal or not and if not will it just go away? Then also can't right click the slider in the drop down list on my trackpad. Have gone into trackpad settings and nothing there fixes it either.
Hi, James. To avoid having to hold your hand on the trackpad you may be able to click to place the line and then double-click back on the dimension to edit the value. That's not normal that you would have to hold it and type with the other hand. When I've used a trackpad I've still been able to release my hand to type in dimensions. Cheers, Kevin :)
Anyone else having problems with getting it to make fillets at 11:42? I can't select the closed part. It lets me select everything else BUT the part I want. Not only that, but Autodesk changed the color scheme. It doesn't highlight in orange.
Hi Kevin, After finishing and finetuning the designed trammel, I wanted to create a video via animation tool - idea is first to see the object for some 10 seconds in motion like you can do it in Design / Animate Model and then still some seconds to explode the object to get better view on it. BUT
I can't manage the animation. It seems to me its only possible to animate each single component in a single time line but not all components together as in the Design tool possible. Would you be so kind and give me/us a hint for this. Thanks a lot Kevin
Hi, rk57chat. In short, the animation workspace does not allow the motion to be played like the Design workspace.
Here are some notes from the Autodesk site (this explains it better than I can off the top of my head):

I would like to see how to make changes after the project is complete. It seems for me it is just easier to redraw.
With the parametric design, you can simply edit sketches and features in the timeline. As long as you design with a specific intent in mind (i.e. what you want to be updateable) you can easily make changes much faster than redrawing.
When I right-click on the top-level component, I get a "New Component" window and I type in "Slider". What appears is just like the video. Selecting the right face works, but then immediately it de-selects the slider objects and makes the track the selected object. Now I can't work on the slider. It insists that I work on the track, and even makes the tab for the slider disappear on the left hand side of the screen. I wonder what is going on. Bug? Different procedure for this version of F360? Did I mess up the timeline somehow? Anyone else experiencing this? I listened to the video several times and followed the procedure, and I still can't get it to offset off the underlying track, but put the lines in the slider component. I try again to create a slider component because the left-hand side of the screen shows no slider, and this time it says, "Slider(2)". So it thinks a Slider component is still there, or it wouldn't have put the "(2)" at the end. ??? I should also add that the track image gets transparent right when I choose slider on the left-hand tree. From 9:35 he goes SelectFace - "O" - SelectFace again. Right after hitting the "O" the tree deselects the Slider and now the Track is the active component. Is there some setting that I'm using that is different that would cause this behavior?
Sir! Is 3D printing it with pla material fine?
Yep, that should work. Just make sure to know your 3D printer tolerances as the clearance is important to get this to work :)
I tried following this and, despite the changes to the UI, seem to have got everything right so it would print. However, one of the Revolute joints is not right. When I animate the joint, it rotates correctlly, but when I animate the model, the arm seems to rotate and move as it should and one slider moves and follows the track, but the other slider stays put although the reference flag, selected from the hole in the slider, moves and follows the track. It's as if the reference point has the Slider joint set up but it isn't moving the Slider object. I've tried deleting and recreating this joint several times, but I'm obviously not selecting something correctly? Suggestions?

I'm so confused by this tutorial. Your toolbar is completely different from mine. I don't have a sketch dropdown. Hell, I don't even have "model" as an option. Only design. Did Autodesk change the program since the making of this video or am I doing something wrong? I'm specifically looking for the slot function and it is nowhere to be found. Pls help
Hi Andrew. The August 2019 update changed some of the terminology and location of things. For example, the model workspace was renamed "Design".
With the new UI you'll find the "Slot" command in the "Create" dropdown, but ONLY when you're in the SKETCH tab. The sketch tab will only be shown in your toolbar when you're in an active sketch environment.
Alternatively, you can search for the text feature by using the keyboard letter "S" to activate the shortcuts box > search for the desired feature.
Here's a video I made covering these critical changes - czcams.com/video/tuZzHcmFtg4/video.html
Why is the Sketch dropdown gone? Who rearranged things and for what reason?
They introduce contextual tabs as they've expanded the number of workspaces in environments that Fusion 360 has. Trust me, from a tutorial standpoint it has been frustrating for me as well. However, from usability standpoints I have been loving the changes and progress of the UI :)
@@ProductDesignOnline Thanks for your response. I had some heated discussions at home with a family member over what's better and your comment settled the debate. It can be frustrating for new users to spend time trying to figure out whether they aren't following the tutorials correctly, or Autodesk did the 'ol software switcheroo and a Google search is necessary to find a forum post somewhere which gives the new procedure.
Thanks a ton for these videos. Appreciated.
Hello, I’m having trouble copying and pasting the slider. If I copy the slider and then paste, the object is not visible... somethings I’ve tried: copying and pasting an active component and copying and pasting the inactive component.
Do you have any suggestions other than starting from scratch?
Hi, Andrew. Try making the top-level component active. Then right-click the slider component to select copy. Then, see if you can right-click on the top-level component and select "paste new".
If that doesn't work, it could be several things...could you paste a link to a screenshot or quick screencast? (Google drive, dropbox, snipboard.io). That will help me determine what's going wrong. You definitely shouldn't have to start over from scratch. Cheers, Kevin :)
@@ProductDesignOnline Just sent you an Email with the Screen Shot
@@33andrewsalamak94 Thanks, I just replied to your email.
Ok, everything is working now and I would like to print this. Is there an easy way to lay all of the components out on the grid so I don't have to break them apart in the slicer?
@@33andrewsalamak94 Hi Andrew. There's no automatic way to lay out all of the components in Fusion 360. You can use the "Move/Copy" command. The other method, which I prefer, is to export your component's STL directly to your slicer. Right-click on the component > Check "Send to Print Utility" > Select your slicer (if not in list select Custom and select the app on your computer) > This will place the part right in your slicer. You can then export the other ones directly to your slicer (same build plate). Cheers, Kevin :)
Ok so I figured out my trackpad finally. light double touch gets the menu box up that you get when you right click. The irony of it. All this time and I find out the day before I get my new mouse. Grrrrr. Ok so heres the weird one. I go to slot command the very same as you and then after giving it width 14mm and pressing ok plus extrude, the arm appears on the same level as the base of the sliders. Not above them as it does with you. Have tried loads to rectify but no solution. Deleted it 3 times and then gone back to copy you in the video but every time this happens. Grrrrr
Hi, James. Trackpads are tricky (and annoying) with CAD... I hope your mouse arrives soon if it hasn't already :)
In regards to the slot command not working, make sure after activating the slot command that you click on the top of the yellow slider. You'll also want to double-check that you have the "Arm" component created and activated. If your Slot component is activated then it may be defaulting to the bottom surface.
Other than that, it's hard to say without seeing your file. Let me know if you get it working, otherwise, if you share your file I'll take a look. Cheers, Kevin :)
Got my new mouse Kevin. Wow how fast you can zoom out. Any advise with it. Like should it be set up a certain way with buttons doing something or just as standard?
@@jamesbarratt593 Sweet! That's great news. I would suggest leaving it set up by default for now (while you get adjusted to it). Then, as I mentioned before, you can assign the side buttons to be "hotkeys" for your most-used commands. Cheers, Kevin :)
All the god damn components, not active, are ghosted on my screen!!!!! What the hell did you do to make all components not ghosted while you have Arm active? I am about to take a baseball bat to my computer!!! I cannot google or find anything to switch them on and now what should be a 10-minute tutorial has my head ready to f-ing explode!!! The default is the ghost all non-active parts. You are doing a beginner tutorial. You have Arm active yet all the components are visible (look active) as if you had the top part of the assembly selected!!!! Therefore you must have turned on some function switched on that I cannot find! Maybe when you do something non-standard in a beginner tutorial you start out by telling your students what you did to get there!
Hi, ctbram0627. If you're having a problem, just ask. No need to get upset.
This was actually a bug that occurred while I was recording. When I re-activated the arm component the rest of the components should have been ghosted.
This is however a setting that you can turn on and off in your preferences. Click your username in the upper righthand corner > Preferences > Design > Turn Off the "Show ghosted result body" (third from the bottom) > restart your Fusion 360.
Cheers, Kevin :)
@@ProductDesignOnline Yeah sorry. I finished and printed it last night. My OCD kicked in though as I could not figure out how you had one part active and all the other parts seemed active as they were not ghosted. It drove me mad try to figure how you did it.
@@ctbram0627 No worries. How did the print turn out? Cheers, Kevin :)
@@ProductDesignOnline It came out well. I will link some pics. The tolerance on the arm pins was a bit loose so I am going to remodel the arm pins and the two sliders to have a revolute snap fit (hopefully). I'll throw pics up on my imgur page as soon as I can.
