If you intend to try this out, I would encourage you to use control point splines instead of fit point splines for the sweep profile. I have only just recently found out that fit point splines do not adjust parametrically when patterned. You can refer to this follow up video for more information.

I’ve watched more than a few of your videos now and I must say I’ve been very impressed from the beginning. Your videos are not only clear and concise but the subject matter is always interesting. The way you breakdown complex and advanced geometry into simple easy to follow commands is unique to this channel. To do all this in your second language is mind blowing. Thank you so much for sharing. I’m so sorry I’m not rich enough to donate towards the channel.
Thank you for the kind words. I'm afraid that I can't really hide behind the "second language" excuse 😀. Although English is not my mother tongue, it is the language that I use most of the time. No worries on contributing. I am just glad to have your time and attention to watch my videos.
Perfectly clear tutorial without annoying music ! Very good quality!
I've been using Fusion for a couple years and never knew you could dimension and constrain spline handles. I love watching these case studies. Very helpful to see how someone else thinks their way through a design process.
Excellent content, best Ive found for fusion!
I really like how you're taking the tutorials in this direction. Making useful things :) Thank you.
My favorite new Fusion 360 channel about to hit 10K subs. Congratulations!
Thank you! Definitely looking forward to that milestone.
Fantastic work as always, yet another cool technique to add to my list of things to try
You think through these designs so well!
Hey dude just wanna let you know you are the man. Excellent, interesting tutorials. Thank you again.
this is simply amazing
Very nice tutorial and once again learned couple new F360 concepts. Thanks!
Great tutorial! Thank you
Very clever indeed !
Love your tutorial
Best Teacher
Thanks! great video as always. Thinking: Might be easier to layout proximal desired hex pattern 1st, then choose cylinder circumference to be a convenient multiple for hex pattern, rather than backing into hex pattern dimensions?
Mmm...never thought of it this way before. It does make sense. It is definitely much easier to adjust the cylinder diameter than the pattern.👍
@@Fusion360School But in reality your dimensions for your project would be driven by something else, such as the size and amount of pencils you want to hold within the container. Otherwise the tail is wagging the dog.
Спасибо. Больше таких уроков
I think a lot of you must be tired of seeing honeycomb patterns and symmetrical splines by now! Will do something new next week.
At 5:30, when specifying the extent of the extrude for the cylinder, I simply clicked on the bottom face of the twisted body. The problem with doing this is that if the height of the twisted body is changed, the cylinder height will not follow. I should have used the "to object" extent option instead. Sorry about this.
Can you do one with the raised bumps/pattern of diamond plate?
Thanks for posting this tutorial it was great!
This video is very interesting. It also sparked my imagination and I was able to use the twisted sweep on a path to create a tapered thread. Thanks :)
It does seem like a diamond plate pattern would work well. Will definitely consider this for a future video.
Thank you for teaching. Could you please add parametric worksflow for your designs? Would be even more helpful to always work that way, its a good habit I think.
Be careful when using fit point spline since they calculate tangency weights at creation, and will not re-calculate when re-scaled or modified. This means that you end up with is a spline where the actual shape and tangency depends on which order you dimensioned the points that it was fitted to. To make it worse you can not display, change or verify the tangency weights in any way that I have found. This is a bug that has been in fusion 360 since day one, and has been reported numerous times in the forums, but it will probably never be fixed. IMO fit point splines should be deprecated, and control point spline should be used instead.
in this example you'd get different shape of the spline in the first sketch with these two methods:
Create the first circle -> create fit point spline -> add dimensions to circle -> add dimension to spline fit points
Create the first circle -> add dimension the first circle -> create fit point spline -> add dimensions to spline fit points
I know this is the case because I spent several hours hunting down a non-symmetry error when using fit point splines.
There is one more bug that might be a trap for young players with this project. Patterned fit point splines will not be updated automatically, which is different from all other basic shapes. So if you have created a spline, then patterned it, and then change the spline the patterned geometry splines will not update. You have to edit the pattern and then save for ot to update. This is a different behavior to how circles, arc, lines etc behave when patterns are used.
@@XerxesGustav Thank you for pointing this out. I have always thought that dimensioning the spline handle would be enough to control tangency weight. I was not aware that order can make a difference. Will definitely need to experiment with this.
I went to test out the patterning of fit point splines again and you are right, the patterned instances do not update when the seed spline is changed. This was quite a rude shock to me! I went to try the same thing in SolidWorks and it has the same problem.
When I tried patterning a control point spline, the patterned instances react to changes! Looks like I would need to do a follow up on this. Will definitely credit you. Thanks again for the comments.
@@Fusion360School Glad I'm not the only one finding the pattern not updating a bit of a shocker. Happy to help :)
It's precisely the dimensioning of the handles that is the problem with the fit point spline. At some point in the code fusion has to do an arbitrary mapping of control handle dimension vs authority of that control handle. There isn't a strict mathematical definition of what for example a 15mm long control handle means to tangency, so fusion calculates something that it thinks is reasonable based on the size of the sketch. That mapping isn't updated when dimensions of the overall sketch changes,.
You can test this by for example making two 50mm long perpendicular lines starting and origin , going out the x and y axes. Add a fit point spline to the endpoints of the two lines you just made. Be sure to only have the two lines's endpoints as fit points to the spline. Make the spline handles perpendicular to the lines. Add a 20mm dimension to the spline handles. You should now have something looking like a slightly messed up quarter of a circle. Now, modify the dimension of the two starting lines to be 100mm instead of 50mm and create a new fit point spline on top of the old, with the same input as before. You will now have two splines with exactly the same definition with very different shapes.
I have reported both of these as bugs to Autodesk, but so far they seem to think that isn't something they should fix or improve.
Can you please do a video on making an "Ambiguous Cylinder" maybe with several different shapes. Should be a fun project, and I'm sure many would love to see how they are created. Thank you, and I always enjoy your videos!!
Are you referring to those optical illusion cylinders that look different from different angles?
@@Fusion360School Yes, those things are pretty cool! and I am having trouble modeling them correctly.
There is one tutorial but it is 1hr and is for solidworks. I went through it but can't seem to get it right.
maybe do some different shapes too, like circle to star, etc. Thank you.
There are no good tutorials on these, so this is an opportunity for your channel as well. More people need to see your channel, it is phenomenal! Keep up the good work!
Sweeping works great, could you also have used the coil command?
Unfortunately, the coil command only has circular, square and triangular cross sections.
Can you do the emboss command on a sphere?
Hi! Fantastic Video. I have an issue however. My circumference came to a slightly less amount which meant that my emboss pattern either leaves a gap with 31 or is too wide with 32. Do you know a way to stretch the entire pattern to get a perfect size on all designs everytime? It seems a little limiting to only be able to do it with the pattern settings?
you have to adjust the spacing to get the correct pattern. it is time consuming however.
Damn I was using projectile to apply schech to a curved surface. Never tried emboss before.
By the way, thanks for your video. I am now workless and trying to make 3D printing my career, and your video definitely pushed me into the direction. Any suggestions?
I do 3D printing mainly as a hobbyist. I spend much more time on modelling than on 3D printing. So I can't really give any advice on a 3D printing business. I think there are quite a few guides on TH-cam. You might want to take a look at them.
@@Fusion360School Thanks for the advise. I'll take a look!
9:26 I would like to learn how you figured out how to get that perfect cycle Diack pattern that does not overlap and interlocks correctly. Did you just use pen and paper with maths or trial and error?
I just did a bit of math to find the circumference of the the cylinder. With that, I massaged the spacing/quantity/size of the honeycomb pattern to make sure that the overall length of the pattern did not exceed the circumference.
Can you do a tutorial about how to make scrolls that mesh with gears/racks?
Are you referring to a gear rack?
Maybe this is a silly question but do you have some option set which allows you to snap the circle to the lobe? Or maybe more to the point, could I have some option turned off because I cannot get it to snap.
got the same problem
Hi, you can go to preferences -> general -> design and turn on the "auto project edges on reference" option.
@@Fusion360School it says "A problem occurred while combining geometry. When joining/cutting/trimming, try to make sure that the solids clearly overlap (problems can occur when faces and edges are almost coincident)."
@@TheTrialfreak When I was trying this out, I faced the same error when I used a height of 120 mm. It seems like Fusion is very sensitive to how the edge of the cylinder crosses the honeycomb pattern. May I suggest that you try adjusting the height slightly?
what did you press at 1:50 ?? i can`t get this to show up. to set that distance
When I try to emboss the honeycomb onto the cylinder I get the error that the faces are not coplanar. How do I get past the error?
got a problem with intersect. trying to combine two bodies got error message:
There was a problem combining geometry together. If attempting a Join/Cut/Intersect, try to ensure that the bodies have a clear overlap (problems can occur where faces and edges are nearly coincident).
Failed to Boolean bodies together
Have used exact the same measures to all object. Can you please suggest what went wrong?

@@Fusion360School thank you - it worked at path length 135mm
@@_assassa_6439 Good to hear. 135 might be a bit tall for a pen, though.
Can you make the head of but metabee medabots without nurbs?
What is that?
How much time you took to print your Pencil Holder..which material do you use? PLA!?
PLA. Took about 16 hours. I sliced with adaptive layers in Cura. Layer height varied between 0.16 to 0.24 mm. Nozzle diameter = 0.4 mm.
I am try to make this and when i need to do combine I have "Error: There was a problem combining geometry together.

@@Fusion360School Thank you!! I am change "path" to 130mm and now everything work.
I've encountered a few issues.
1. Even though I've fairly performant PC with Intel 8750H CPU, emboss operation takes quite a long time - about two minutes. Should I buy new PC with faster CPU? Or do I need better GPU than NVidia 1050 Ti ?
2. Combine/Intersect operation failed, when performed according to tutorial, because faces of bodies were nearly coincident. After increasing diameter of embossed body, body intersect operation succeded.
I have a fairly good pc and it still struggled with the emboss. Many users with good pcs struggle with handling complex sketches. A number of users had the same intersect problem. A slight adjustment to the pattern or the body should do the trick. This problem seems to arise sometimes when the body crosses the pattern in an awkward way. Usually, for my videos, I would test the model quite a few times using the same dimensions and I did not face any issues during testing. This seems random.
great tutorial but never waste plastic building such ugly things
