The ethereal music and calm tone of your voice made me feel like I was on a ride at Disney then as you added more detail to the pumpkin I was struck by the beauty that God had put into the design of the pumpkin, and finally it seems as if you were overcoming the forces of gravity by modifying the pumpkin's design. Your art is as much the process as it is the finished piece and I am very grateful for your generosity.

[@antronk]

This is one of the best and most polished tutorials I've come across witin the community. I also really liked your final remarks about design iterations and prototyping (often left out in other software-only tutorials). Extremely insightful for 3D printing oriented applications Thank you so much!

[@3DPrinty]

Thank you!

[@octopus1613]

oh, plus, the lil pumpkin line drawing while you were explaining the spline? very cute. I love it.

[@Mark-fj5yz]

I would love to see more videos like this designing other things.

[@3DPrinty]

I'll look out for similar projects that are simple enough to fit into a video but sufficiently complex to cover a range of modeling tools and techniques. Thanks for watching!

[@weisnowhere]

Wow! Great tutorial definitely going to try and design my own! Really appreciate pointing out the considerations required for a successful 3d print! A lot of other tutorials aren't directly aimed at 3d printing and miss this info! Thanks!

[@3DPrinty]

Excellent, good luck modeling! I really dislike printing and removing support material, so any time I can design around it, I'll do that :)

[@octopus1613]

Very cool! I was thinking it would be way more complicated, lol. Several Fusion360 features I haven't used yet, but which look very useful. Also, you did a fabulous job of explaining. Very good tutorial. 10/10.

[@3DPrinty]

This program just keeps going on and on with features! I didn't even talk about how you can use rails when lofting shapes to guide how they flow - in this case the shapes just worked. I'm glad it was useful!

[@octopus1613]

@@3DPrinty Very useful! I never used a loft before, and I'd previously wanted basically exactly the project-intersect feature, but didn't know it existed, and basically had to do some complicated math to figure out the exact position. (thankfully that was a very geometric shape, and highly parameterized, so I was able to create a formula, but still, do not recommend.) I'm making a pumpkin right now, and having a lot of fun with it. Currently not having the arcs match all the way round, for a more organic look, and it's making for a fun lumpy pumpkin. With one rib that's perfectly smooth, cause I wanted to see how it would look if I had the arcs tangent to the polygon lines adjacent to them. I might be doing more slices than necessary, idk. Still having fun though. And! That revolve you did near the beginning? I put a small offset on my profile spline, and revolved that, to cut out a hollow! I don't know how printable this pumpkin is, especially with the hollow (the top would DEFINITELY need support, especially since my stem is much more inset than yours, so it has a sizable dip), but it is a good learning experience and I am having fun! I also attempted to have the co-planar sketches in the same sketch, and learned why you didn't do that. It doesn't play nice with the loft feature, lol.

[@3DPrinty]

I hope your pumpkin experiment goes well! If you examine how I modeled the inside of the Twist Lock Pumpkin Box, you'll see one way to use an internal chamfer so no supports inside will be needed!

[@moshibass]

Wow this was fantastic. I've dabbled a little bit in Fusion 360 but now I see I've been doing everything all wrong haha

[@3DPrinty]

There are a lot of different ways to go about it, so I wouldn't assume your way is "wrong" or that my way is "right". I guess it depends on what a specific project needs. That said, it's good to know as many ways to do something as possible. Happy modeling!

[@moshibass]

@@3DPrinty I agree! That's a great way to put it. In my case though, I was coming from Tinkercad and never really knew what sketches were for! So it was great to see someone with experience use the program. Thanks again!

This was great! You explain things very well, I bet you would also teach compliant mechanisms really well too. Just an idea if you're looking for more potential tutorials!

[@3DPrinty]

Thank you so much! If one of my future designs use the technique, I'll definitely go into more detail on that!

[@whatsthatbutton]

@@3DPrinty I would imagine so since you have so many 3d printed springs you're just around the corner from that haha Thanks a lot for the existing videos too, super useful for a fusion novice

[@MarcSolomonScheimann]

Thanks for sharing your design process, and tips. Interesting to see that you don’t fully constrain your sketches; I was always told that this is best practice. Is there any reason that you don’t? Or is this more particular just to the pumpkin, that is very organic in shape?

[@3DPrinty]

I'm glad you asked! Yes, typically I fully constrain all my sketches. But sometimes (as with organic shapes) it's helpful to keep the design loose. For example, earlier in the video I manipulated a revolved shape outside of the sketch view. This wouldn't be possible if the spline I was moving had been fully constrained. Fully constraining sketches is still the best way to go in most cases. I hope that helps!

[@JordanKicklighter]

@@3DPrinty For this particular object, I would probably leave the spline unconstrained (for reasons you mentioned) but constrain every other sketch so they are guaranteed to respond correctly to changes in the timeline.

[@suburbansamurai3560]

Is there a way to maybe duplicate the horizontal plane with the curved bumps around the circle, and just offset a duplicated version instead of reconstructing each one? Fusion 360 expects a lot of abstract thinking to get the shapes you want!

[@3DPrinty]

There isn't really a good way to duplicate the entire sketch entity, but you can copy the CONTENTS from one sketch into a new one. Since I was resizing each slice anyway, I figured it was about as fast to reconstruct it on each layer as it would be to copy/paste and resize. Thinking of 3D objects as a series of sketches takes a little getting used to, but once you've completed a few projects it gets a lot easier!

[@ExplodingWaffle101]

I've been using fusion for YEARS and 2:35 blew my mind. I could've sworn you needed to go into the sketch to edit it like that- has this always been a thing or is it a new feature?? Either way, very cool- guess you do learn something every day :)

[@3DPrinty]

There’s just so much to this program! I’m still discovering new things every week. I believe this has been possible for a while, but I don’t recall exactly when I first found it. Most of the time my sketches are fully constrained which, of course, would make this impossible.

[@kamilludwicki4957]

Same. When I saw this I was like WOOOOOOOOWW 😃

Cant sleep so ill print a twist lock pumpkin

Brilliant stuff. Keep up the good work.

[@3DPrinty]

Thanks, will do!

[@noweare1]

This was kind of complicated for me. Just beginning with fusion. I ended up making a sketch of the pumpkin profile, revolved it 45 degrees. Made a sketch on the face of the revolved body just like the first sketch. Deleted the body. A 3rd sketch on the xy plane where pumpkin diameter was largest, and projected intercepts. Got two points, one from each sketch and made an arc which is the bulge. Then used loft tool using arc as a rail. So now i have 45 degree slice of pumpkin. Then used circular pattern to complete the rest of the pumpkin. I think it is kind of like how you did it without first starting at 360 deg. And I did not use as many planes as you the get the bulge.

[@3DPrinty]

That's a very good way to model it :)

[@kimpanella1565]

I am very new to Fusion 360 and I get as far as Project and Include > Intersect and it doesn't drop the purple intersection point in. Any ideas on why?

[@3DPrinty]

I believe the user interface has changed slightly since the video was published, and that may be throwing you off. Try this: 1. Start your new top sketch, just as shown in the video. 2. Select the line you want to create an intersection point from - make sure it's the entire line that's selected, not a point on the line. 3. Go to Create > Project/Include > Intersect. 4. A new "Intersect" tool box will pop up with an "OK" button. All the default settings in this box should be fine, so just hit the "OK" button. That 4th step is the part that's different from what I shared in the video. If this still doesn't work, make sure that the line you drew for the side of the pumpkin actually extends far enough for there to be a valid intersection point. If the new sketch is on the top origin plane (the X/Y plane), but the side of the pumpkin is floating entirely above that plane, then no intersection exists and the action will be ignored. I hope that helps!

[@jameslam2848]

Hi Like your designs 👍 I have prusa mk3s+ your print came out with clean lines how do I adjust my printer to do that help please

[@3DPrinty]

Thanks! This is a huge topic, before I go into tips and tricks, you should know that how good or bad a print looks in a video has a LOT to do with lighting. I can make a wonderful print look terrible or a terrible print look quite good just by filming it at a particular angle. Don't be discouraged if you see prints that look better online than in person. Prusa printers are generally known for quality prints, so putting the printer itself aside, the factors that affect quality the most for me are: 1. Filament quality Look for filament that has a tolerance of +/- 0.03mm or better. These were printed in Prusa sample filament, which isn't an exciting color, but does have good consistency. I use cheaper filament for prototypes, but for gifts and stuff I want to show off, I look for brands I know have worked well for me in the past. Whenever I can, I use up a roll as soon as I open it. If I HAVE to store a roll, I keep it in a dust-proof bin with desiccant packs. I've tried using filament driers, but I think they're only really worth it for non-PLA filaments. Better to just use stuff up right away. 2. Print Speed I almost NEVER print faster than 100%... and I'll often drop to 90-80% speed if I'm printing over night. Fast printers are impressive, but I'm not racing. That said, printing too slow can also cause problems. 3. Printing Environment Print in a room with no drafts, has a consistent temperature, and minimal humidity. My printers are in a dry basement away from any AC/heater vents. 4. Configuration Pay close attention to temp ranges and tweak as needed. I recently started printing with a sparkle red Hatchbox PLA I really like, but I didn't get good results until I lowered the temp a whole 5 degrees LESS than the range they advertised. Different colors in the same brand may need different temperatures, especially if they have other additives. If you're using a new Prusa and prints are not turning out AT ALL, it might be worth reaching out in their forums. It's not impossible that you have a bad hotend or something that's giving you a worse time. It's obvious that I like Prusa printers, but it's not like they are magic and never have problems. Forums are a mixed bag, but I've had good luck there. I hope this helps!

[@jameslam2848]

@@3DPrinty Thank you very much I’ll give it a try 👍

[@bigdaddydonagaming6652]

The I try to coincident the circle to the arcs, it makes the circle and arcs off kilter.

[@bigdaddydonagaming6652]

Figured that out, how do you select the whole layer when you loft? Mine make like 100+ profiles and says failed

[@3DPrinty]

This is one of the benefits of using "construction" lines (the dotted version of lines). If you set everything except for the exterior arcs as construction lines, Fusion 360 will treat that entire area as a single complex shape. Or as the program calls it, a single "profile". This should make computing the loft simpler, because it won't have to process any internal edges. Good luck and I hope this clears things up!

[@markbutler7205]

this kind of thing is sooo frustrating. The loft tool does not work like that for me, when I select a profile, all I get is one piece of each sketch. I tried selecting all of them on a specific sketch but it gives an error...sigh. Fusion 360 is so difficult to work with

[@3DPrinty]

This is just a guess, but your profiles may not be using construction (dashed) lines where appropriate. Construction lines don't dice up your profile shape, and that makes selection much easier. I can't think of any other reason a profile would require clicking multiple parts to select the entire shape.

[@proto_hexagon5649]

nice deasing

[@3DPrinty]

Thanks!

[@Mainric]

Классно!

[@3DPrinty]

Спасибо большое!

[@ansiaaa]

isn't there a way to avoid creating all those similar sketches by hand? you have the first one, and then you might be able to copy on various height?

[@3DPrinty]

Absolutely! You can do a sweep with a single profile and 2 rails. However, this will give you less control over making an organic shape. I wanted the pumpkin ribs to morph a little as they curved around.

[@ansiaaa]

@@3DPrinty yeah I can see that other method working in a different way, but let's say I actually want all those copies on different planes, with different measures. isn't there a way to copy one sketch and then resize it somehow?

[@3DPrinty]

Yes. If you want you can select and copy curves within one sketch and paste them into a new one. In my experience, this sometimes loses some of the constraints from the source sketch, so I tend to redraw rather than copy/paste.
