0:00 Intro
0:35 Split line for starting edge
1:12 Rail construction using intersection curve
6:16 Surface loft
7:30 Solid extrude up to surface
8:18 Alternative method
That second method that didn't create an intersection curve blew my mind! Thank you for always showing innovative ways of approaching problems. You're hands down the best Fusion 360 instructor on YT.
Very thorough examination of functionality and multiple workflows. Best fusion 360 tutorials available.
Awesome again
The third (and easiest) method would be to use the Curved Ramp command. 😉
Thanks for another great video. You could also create the rails by creating 2 planes - one between the inner 2 edges of the rectangles and another between the outer 2 edges. Extrude the body vertically, then create a sketch and Project>Intersect on each construction plane to create the rails for the Surface>Loft. , then use the surface body to cut the solid body, and Remove the upper section, and combine the lower section with the original body.
That is definitely a good approach too, similar to what @JustinLin has suggested.
This is one of the most helpful Fusion videos I've seen yet. Thank you so much!
Thanks!
Thank you for the support!
This is a very addictive channel to watch, I love it!
Your voice is so calming, i wish you would make Tutorials for other Software i use
Nice video sir
I never would have thought of using the first method. Very intruiguing! Thanks for this!
Nice workflow. I see this geometry as a helix surface and would do a surface sweep (path = axis of arc faces + 180deg angle) and use replace face using surface body (still need to split the arc face from rest of body). But now the challenge is to make the slope tangent to start/end face ;) have a nice weekend and take care :) .
Ah, a sweep with twist. Did not think of that. Will definitely need to try that out.
Very clear workflow as usual! Reminds me of a real struggle I never solved - making spirals in fusion 360. In solidworks you can use equations and stuff but I've only ever managed a helix. The end result was meant to be an archimedes fan but it never really worked
This will be helpful with drawing up a mandolin scroll. Thank you!
Amazing workload! This blew my mind! Thank you for sharing
A masterpiece! Thank you. I have been struggling with such thing for a while. I hope it will work in more complicated 3D curves. Lets go back to work
I've learned a ton from you. Thanks so much for taking the time time to create these videos. Very clear and straight to the point.
I remember the olden days of sitting through 30 minutes of Lars' blabbering, waiting for him to stop talking about useless BS and start teaching. When I found this awesome channel, I unsubbed from Lars and never looked back.
@@ZPositive Exactly my experience as well! IMHO, this guy is the perfect teacher.
@@richwp5580 LOL I love finding comaraderie in random internet strangers. I remember the exact moment I unsubbed from Lars, saying to myself in AvE's voice "smell you later!"
Lars is the worst. Almost turned me off to Fusion. Everyone raved about him but I found his tangents and droning insufferable.
@@JuanAdam12 I couldn't agree more. We're so fortunate to have found Fusion 360 School.
Nice video, may I suggest you : get lines rails as in the first method, then extrude as in the second method, then use solid loft from one rectangle to the other with rails to cut to remove the upper part. Always a solid approche 🙂
Very timely. I’m doing something similar right now and this will help. Thank you.
as always - amazing!
Thanks a lot. As always very informative. Love your videos.
Awesome, thanks for teaching us this!
Thank you
Hai saya dari Indonesia.
Terimakasih anda sudah membuat video tutorial yang sangat baik
Excellent video! I learnt al lot!
3rd way you can create 2 workplanes using 3 points (one for each wok pane) and project each radius to each sketch and obtain rails for the loft
Nice! 👍🏼
satisfying
I think more explanation in some of these steps would be helpful. For example, WHY at 3:29 does the selection order matter?
I think you might be able to use the coil tool to do this. This method would not be as flexible though, because it assumes that you are trying to follow a circular path. I guess what's kind of nice about coil is that it directly expresses the intent here: the surface you are going for is helical.
The coil command is definitely something to think about. From what I know, the coil command is not able to create a sketch. It can only be used to do a solid sweep. It might be possible to use the include 3D geometry command to project the solid coil into a sketch. But it might be difficult to join that to the existing body. Will definitely need to experiment more on this.
🙌🙌🙌🙌🙌🙌
It's very nice to show how intersect works and how one can work with sufaces.
However this example could be created very short and easy with this ramp, after you splitted it.
You then have more bodies and could hide the middle one and easily loft 1 face from one body to the other face of the other visible body with the curve of the sketch as a rail.
Having said that - always love the vids you do and the way you give a perfect explanation, even for beginners! Much appreciated and big kudo's for that :)have
That sounds good too. In this way, we would be doing a solid loft with four rails, with 2 of them from the sketch used to create the starting model. It might be possible to control the loft with just 2 rails from the original sketch.........definitely worth trying.
I just went to experiment with 2 rails, using the original arcs used to create the starting block. The bottom edges of the the loft were able to match the rails exactly but not the top 2 edges. It is very close though!
Thanks for the quick feedback - I tried it and only used 1 rail (from the sketch - make visible before) - the outer rail - and that worked perfect 😉
👍👍😎👍👍
Nice thank you for this.
I wonder if there is a way to remove the screw effect. I assume that the inner splitting arc would need to be curved also in the z direction. I mean if you imagine a car driving up that ramp the car is leaning outward, I wonder if theres a way to counter that.
To really customise the curve, one possibility might be to replace the straight line with a spline. Some have also suggested performing a sweep with twist to achieve a helical surface.
That was great! now could you expand on this and show how to create a simple semicircle track that follows your path consistently? for rolling a marble for example. I can get it to half work but the track ends up shifting from the expected end point, and it is not symmetrical.
A track definitely sounds interesting. I think another challenge would be how to maintain a consistent width along the path. Maybe a shell. Will consider this for a follow up. Thank you for the suggestion.
The first method does not seem to work when using a quarter circle though since one end of the curve isn't normal to the plane the intersect curve is projected on. I can't seem to find a way to do it for a quarter circle using the first method. Using a spline instead of the straight line doesn't work.
Can't you achieve the same result a bit easier with a sweep that uses a guide and surface alignment? I've done quite a few similar things and that seemed to work well for me.
first split using face can cause issues if model changes (legs becoming not parallel). better to split using a line from the arcs' starting points.
That's a good point.
I am struggling to replicate an object on F360. Any chance you could make it a study case out of it? Great videos by the way.
You can send me the details via tanwinghoe1983@gmail.com
I'm trying this in Solidworks, as I usually use it for my work & I can't seem to figure out how you can perform sketch intersections like the first method shown here.
In solidworks, you should be able to use the project curve command to produce the same result. I actually think it is more powerful than the intersection curve command in Fusion 360.
@@Fusion360School Thanks, I'll check that out, I did manage to get the final result but it felt like I took 4-5 steps too many.
Btw really enjoy your videos, great way to learn new techniques, keep up the good work!
My approach before watching the video will be:
1. Create 2 plane from 2 lines.
2. Project the curve to the 2 surfaces.
3. Loft.
Let me see how is your approach.
To be very honest ,I have never used the Intersective curve in my whole life haha. Learned something today!
That is a good approach too, similar in spirit to the intersection curve command. I'm always glad to see viewers thinking about how they would approach a problem before viewing the video. It is a very important learning step. It's just not the same if you just look at a solution before thinking about a problem.
@@Fusion360School Yeah, cannot rely on the internet for everything right.
Jlb pcbs
i used loft in two clicks
I feel like there is a faster way to do this??
Second method is definitely faster and interesting but was thinking of a third. I must test before speaking too soon.
I use Fusion professionally. Is there a way to book you a a mentor for 2 hours?
Thank you for considering me. I have been asked this question once in a while. However, I would have to decline. I really enjoy the content creation part. However, I don't think I would enjoy coaching or any kind of paid gig. Any arrangement that involves money would come with obligations. That often takes the fun away. I would like to keep things as casual as possible. Also, I am not a good "live" teacher. I often tend to need more time to analyse a problem and really test things out. That said, you are more than welcome to send me any questions you have via email (tanwinghoe1983@gmail.com). I would try my best to give some pointers. Sorry about that.
Wouldn't it be even simpler to just use the loft feature directly?
After splitting the body as shown at 0:55 you already have two rectangular faces and two guide rails to use for the loft.
The intermediate warning that the two faces shall not be co-planar can be ignored as it will go away as soon you select the guide rails.
No need for any additional sketch or construction lines. Granted, the "vertical" curved faces of the resulting body are not vertical anymore, but wouldn't that rather indicate a F360 "bug"? To me it's not quite clear *why* F360 does this.
BTW, a well meant hint on the pronunciation of _"edge"_ I have watched other videos of yours and I just can't help hearing _"age"_ where you obviously mean _edge_ .
This might be a good place to _hear_ the difference of the two th-cam.com/video/PlimY9bmNgc/w-d-xo.html
This is a fair point. It was also suggested by a few others. When I went to try this, like you said, the "vertical" curved faces of the resulting body are not vertical anymore. It is very close though. I am not sure whether this is a bug. My thinking is that the top 2 edges of the loft needs more direction, which is where the projected rails can be useful. If precision is not a concern, your suggestion is definitely a viable and simpler method.
Sorry about this. A few others have pointed this out to me as well. I have tried and I am just unable to get the correct pronunciation in a natural way. This will have to be a work in progress.
@@Fusion360School Thanks for the quick reply 👍
I have played a bit more and found an _only slightly_ simpler way of getting the exactly same result as yours.
I'd start with the same approach as your second version, with an extrude of the top surface of the U shape, and a sketch of the two lines, but instead of using _Include Geometry_ plus _Intersection Curve_ or _Split Face_ plus _Surface Patch_ I used _Project to Surface (Along Vector Y-axis)_ and then used the two resulting curves together with the two bottom curves of the original U shape as rails for a loft of the two rectangular cross sections obtained with the very first split body.
