Lars, just watched this, Thanks for all the wonderful tutorials you send out. One solution to fixing the "twisted" swept profile is to pick the Path + Guide Surface option for your sweep and pick any surface on your initial "seed" coil. Thanks --Monte
To prevent it from twisting, use both rail and guide. Grab 2 edges from the internal "dummy coil" - use one for rail and one for guide. I can't remember which is which, but try one or the other as guide or rail.. (it's been confusing fusion users for years if you watch various guides for coils :) )
To ammend my own comment: If you just included that one profile from the "dummy thread", you can use ' "Path + Guide surface" under Type when you do your sweep and use the surface of the cylinder you make the thread on as a guide. Sweet!
I'm getting so much from your videos. You are truly a UA-cam and Fusion360 asset. Thank you. I will try to watch every single video you produce because each one is filled with experience and knowledge.
Hello Lars, Your best source of data on thread finish specs. would be SPI, the Society of The Plastic Industry. They used to publish a very complete guide that covers all of the standards that allow a company to create a mold, and then a bottle that can use an industry standard closure. All of the standard thread finishes are called out by the T dimension, or major diameter in millimeters. I had made a lot of prototype neck finish tooling with milled threads, using a form ground milling cutter. To get the thread form to come out correctly the cutter must be in alignment with the helix angle of the thread. The circumference of the major diameter as the side adjacent, and the thread pitch as the side opposite. I am unsure if this helix angle could cause the problems that you showed. I do believe that I remember seeing this subject discussed somewhere on Auto Desk in the past. Your sessions have helped me a lot with Fusion. Now it is time to try to help you.
Hello, Lars! I'm so delighted to watched the episode. Thank you for answering my question. Now I've learned how to model bottle thread using best practices. Warm regards from Kano, Nigeria 🇳🇬
Could the reason for the twist not be that the thread was initially drawn at 90 degrees to the plane that you were working in, instead of 90 degrees to the helix? Which might also explain why the revolved edges look different?
Actually, the problem you faced with the helix is a standard issue in Fusion with helixes. Has been there for a very long time. Doesn't happen in Inventor, though. That's something that really needs to be sorted out. This piece of software has so much potential and it's so great and then it has a basic little bug like that
I tried to use Autocad about 20 years ago to make thread (it did not have a tool built in) and the sweep would twist just like this one did - except there was not "twist angle" to correct it. (or at least not one I could find.)
It's a pain, yes, and has been bothering other Fusion users. The trick is to include one more edge from the dummy thread and use 'guide + rail' under Type when doing the sweep, or.. use "Guide + Surface" and use the surface of the cylinder as guide surface.
5 thumbs up for the revolve on the two end planes to round off the ends! Next request, a male/female twist-lock thread. I am working on this now, need to join 2 cylinders such they they align at an exact point, e.g. 1/4 turn twist and they lock together at the correct point. Thanks Lars, really enjoy your tutorials!
model male side as above. model female end as needed as a seperate component. Bring the female component into the male design as position as needed. Then use the male side to "cut" the female threads, while having "keep tools" checked so it doesnt delete either male side, only the threads from where they intersect the female body. This can also be done by choosing intersect instead of cut and keep tools, then deleting the body that is created (as that is the threads inside the female body.
Third try, just to be sure Lars has seen it: Hi Lars! Please, make a video on how to handle warnings and errors. It happens that you have been developing a complex assembly, then change something altering early created sketches and, voila, you get multiple errors and warnings... How to tackle with them? Thank you!
I used to have the same, after watch almost all of Lars videos. What I learned was that I was not setting up my work flow right, here a good video to watch from Lars ua-cam.com/video/wbtv3NmWZEg/v-deo.html
Very interesting lesson. On the thread design though, anything you do from 13:26 and on is not realistic for a thread as all bottle/cap threads taper in both vertical and horizontal planes so that you essentially have two tips of an arrow meeting so the cap and the bottle have an easier time agreeing who is on top.... Caps and bottles have problems when the tips of the threads collide.
Thanks you for sharing your ideas. I like the way you did this. I like the way Inventor does it better and easier. It has always bee frustrating in Fusion to do this with a custom profile.
Great video Lars! I need to make a box for some parts I am making. Can you do a demo with Sheet Metal tools using Card Stock? I am looking to fold the card stock in a way to have double thickness outside walls and to have a flange of the card stock pass through the horizontal midplane inside the box with cutouts to hold the part the box will contain. If you could show how this could be done, I would be grateful.
Lars.. Glad your back... Great vids.. Perhaps you can answer in one of your videos how I can project from a component in a main assembly drawing on to a component, say for a hole, but then move it to the that base "linked" part and edit the base part instead having the on in the main assembly be different than the "linked" part.. Sometimes its easier to edit the part while in the assembly but I really like the linked parts being separate and complete.
Not a stupid question, in fact I was just wondering that too, but I suppose that you just have to extrude the thread you created inside the cap ? (I don't know if it's clear)...
Hello Lars, I really love your Videos and also my son was watching them to learn more in Fusion360. For my wifes garden I built a Ram Pump so far, but need an adapter part to connect an 1" pipe thread with a thread of a Coce bottle (only for the test). The bottle thread works great in the test print. Now the lenght of the 1" thread is 18mm. The diameter starts at 33.5 and ends 31.8 on the outer side. How can I do that? I hope you find time to help me with this problem.
I am struggling with threads in fusion. How thick should a plane be to apply a thread? I did a pipe with an outside thread and it cut through the pipe’s wall. In need an outer diameter of 25mm and as much space inside as possible.
Hi Lars, I have a st10y and the question is how can I create tool path with the Y axis instead of C axis? Everytime I make a tool path C axis is moving and it takes forever to make a simple pocket... thanks......
Hi Lars, Great tutorial as always! Im having trouble selecting a face after selecting the Shell command. It worked the first time but then I restarted the tutorial and I can't get it to work. It must be something easy I'm missing? Re Justin
Does anyone know if the coil can be re-oriented? I want to start the thread at the back of the model not the side but I can't seem to find a way to select a different start location. Any help will be very much appreciated. Thanks in advance!
As soon as I clicked the revolve, at the beginning of the lesson, my origin graphic disappears from the main screen and I've got to turn it on under the browser by selecting the "Origin" lightbulb. How does Lars have his set that the origin stays on when revolve is clicked?
Hi Lars, What's the best way to allow clearance when doing the Boolean subtraction with combine, would you just scale the cap a tad after creation, or is there a better way. Cheers for your excellent tutorials mate!
When you click new sketch by right clicking a face or plane it automatically seems to go to a “look at” view (not sure the exact terminology of that view). My free version doesn’t do that. Is there a setting to make it do that? Thanks!
Hello, how can i do one especial thread, for exemplo: Externa diameter 350 mm, internal 290 mm, pitch 28 mm. But I need that's pitch with a 2 mm channel and 26 mm elevate part.
For the Europeans (or especially the Germans): One of the most common PET Bottle threads is available on Thingiverse (and so far worked great for me :)): www.thingiverse.com/thing:2693686 Unfortunately, it needs to be copied back into Fusion360 after every update, which is rather anoying - @Lars Christensen, is it possible to import thread data like that in a more persistent manner into Fusion360 (or could this even be included in the thread library in Fusion360)?
He chose internal so that the vertex of the triangle was touching the other body. He wasn't trying to model the thread, just the path of the thread which he creates later with the coil.
Jesus you sould not maybe give us the link? I have been searching for an hour on the site and cannot find it. Scrolling back and forth in your video is frustrting!!!

Thanks, Lars. This will be very helpful for those situations we find ourselves in where we want to model oddball threads.
If you select "Path + Guide Surface" as "Type" on the sweep command and select the bottle neck as the guide surface it seems to eliminate the twist.
Thanks for this comment, that one works like a charm !
Thanks Lars! Would you please match a cap to this thread with some clearance?
Just found this video. On the sweep, under "Type" try changing to "path + Guide Surface" and it seems to stay ok and not twist while sweeping!
This did it for me! thanks
whos up for a video on the inside of a tube ? i am! thumbs up so Lars knows were interested, thanks for this video!
This is the best Fusion teacher on youtube. thanks for posting these.

Select Type of sweep as Path + Guide Surface and the select the cylinder as the surface. Doesn't twist.

You could do the same technique on the inside of the cap, or project that bottle thread to a sketch and revolve/cut out of the cap.

Did anyone figure out where to find the geometry of the thread?
See my comment above
Sorry, which comment are you referencing?
In researching this, I found ASTM Standard D2911 "Standard Specification for Dimensions and Tolerances for Plastic Bottles" to be helpful. Steve
Why was there a twist? Can anybody please show how to make the counter part?
Use Path + Guide Surface as type of sweep.
401 thumbs up.
None down
Nuff said.
Why not just use the thread command ?
The thread command does not have all possible sized. This is very useful for custom or unusual thread sizes.
Grate 😉
should have been an external triangle on the coil. You chose internal
He chose internal so that the vertex of the triangle was touching the other body. He wasn't trying to model the thread, just the path of the thread which he creates later with the coil.
