Great tutorial. Like you I am a relative newbie to FreeCad but I am trying to learn with a much older brain. So many ways to do things in FreeCad and I've watched several different videos and methods of doing threads but your method worked for me the first time. Also, great tip on constraining the thread profile to the through hole instead of the center line. Thank you.
This is not only the best threads in freecad tutorial that I have seen, but as a beginner, very probably the best and clearest general freak head tutorial. I didn't have to stop and hit pause 1000 times but maybe only 10 or 20 absorb it all. I had struggled with free cat some a few years ago and left it behind and it just got back into it now that 1.0 is out. The biggest lack I saw in it for my purposes was easy threads. This is not quite TurnKey but it is fairly easy to understand and use. I just liked and subscribed, and if I see more of these you may want me as a patron too. I make a very smal monthly donation to 4 machinist channels and this may well be my first one outside of that genre. Looking forward to exploring your channel more, and thanks so much for this video. Superb!
Excellent explanation of the tools, constraints, etc. It really ALL made sense.
That's one of the most clear explanations of creating threads that I've seen.
Thank you
In a field of great videos, I really think this is one of your best ever. Congratulations Kevin. Brilliant, useful, readily-followable work.
Perfect speed to follow every step and explanation! Very good! Thank you!
Probably one of the best tutorial for any subject I’ve ever watched.
Excellent explanations for any FreeCad beginner like me.
FreeCAD has come a long way since I last looked at it. I think it's time to give it another go. Thanks for this video.
The sound and tone are nice, and it is easy to listen a great job :) thanks
Very clear instructions - you do these tutorials very nicely, thanks. I wouldn't have know where to start doing threads manually, but it makes perfect sense.
Very good for first time Freecad video Kevin, especially your good explanation of what function to get from where.
Science fiction in your own home. That’s what 3D printing seems like to me. Very interesting-first time I watched the design and creation of a 3D part. I checked the NPT thread dimensions and your 0.0174 measurement was dead on with the listed value of 0.01743. Hate plumbing but love your videos.
Excellent! A couple years ago, I was trying to create broomstick threads and gave up in frustration. I'll have to try again after watching this!
Aside: US broomsticks are usually 3/4" 5 TPI ACME, versus the standard ACME pitch for that size (6 TPI). Most real-world broomsticks also have about 5 degree taper.
You're a good teacher. You may know this, but you could have saved a bit of time. For example, you could have added the holes to MainBodySketch when you created it rather than drawing them on the surface of the body and pocketing them. Another time saver - when you chamfer or fillet, you only need to select a single segment of an edge. Since all your chamfers are the same depth, you could have selected everything you wanted to chamfer and done it all at once.
Adjusting layer height in the sketcher to create better threads was informative, and I appreciate you actually printing and demonstrating how the part fit on the pipe. Nicely done!
All the above are true... He made the part he wanted but had to go thru tha math and ignoring the taper form of mast end. FreeCAD Hole tool can make almost of all standard threads (including tapered threads) and playing with tolerances too. He mentioned that the Hole tool is just for metric but it's not true. The same applies to DIES within the Fasteners workbench both metric and imperial systems (blue icons are for Imperial and yellow ones for Metric.
You make a pretty good teacher. I started by forming a cross section and rotated it Then I got into trouble Now I will just use a 1mm thick circle and then a smaller drawing and add a 4 mm thick part and see if that works better. Years ago I learned autocad but that makes for problems as I always desire using autocad commands. Thinking of making a 1/2 inch to the foot model of a steam engine.
Thank you, this video is awesome! Definitely the clearest explanation of this I've seen.
Clear instructions and at a speed you can follow by. Thank you.
Nice tutorial.
I was also fighting with threads last time. FCad sucks with threads even using thread workbench or fasteners, so finally I also had to design them manually.
Very helpful, perfect speed to follow steps, thank you.
umm I dont know how many freecad videos you have already made but you need to make more! Not going to bash other people but I am part of a group on social media and when I asked if anyone else had issues following a certain individual I got chewed.... Its not in my head I just introduced my mother to fc she has done cad since the 90s and she also got lost. Thank you for your hard work!
I have a few. If you go to my channel page, I have a playlist for free CAD videos. Just getting started with it though.
Nicely done tutorial. Nothing wrong with the way you did that. Making a cutting tool is one of the easiest ways to make complex objects. Dress-ups should always be saved until last - that is just good design practice.
I can recommend 'Open Source CNC' for using the CAM bench and modelling useful things, 'DuyQuang Dang' for seeing what is possible and definitely do the projects, 'OffsetCAD' for modeling real world object, 'MangoJellySolutions' as one of the most polished teahing channels, and 'Katt Kushol' for practice work, Assembly workbench, and some Sheetmetal workbench.
There are few other English channels out there but they haven't uploaded in a while (like Joko Engineering) and most of the rest are silent films and time-lapse silent films. The "Watch me make THIS" tutorial that teaches nothing.
Those are all good recommendations, especially MangoJelly. His new beginner series using FC 1.0 is great.
I just discovered DuyQuang Dang a week or two ago; if you want to create art like sculptures and rings with FreeCAD, he's your guy.
Even though Joko hasn't been producing new videos for a while, some of his stuff is still relevant. One video I found especially interesting was designing headers for an car engine. Getting the pipes to twist together was something I'd never considered before.
Great tutorial! Need more of these! :)
This is very helpful for CAD newbies like me!
Very helpful! FreeCAD sure has come a long way since I last tried it out. I'll have to give it another chance.
The RUclips channel, mango jelly, has some excellent beginner free CAD tutorials. I can't recommend his channel enough.
Clear and concise, time stamp to the thread creation would have been nice, 18:58
Thank you
At 1:24 in the video I say, if you want to jump ahead, and I put the time on the screen. You must have had a particularly long eye blink to miss it over the several seconds it was on the screen. ;-)
Nicely done Kevin! Thanks
This makes a great project, worked great.
Thank you for this tutorial very helpfull
John
Nice tutorial, as an design engineer I would take a slight different approach in several details.
In the end your way is very approachable to get the things at hand done fast without a hitch, what porfits diyers most.👍
Thx a lot for this clear explanation
Thanks for your help and help 😊
Great video I will say constraints are something I need go get used to and can be the biggest pain in my butt.
Great job! That's very different from SketchUp!
Great. Thank you Sir🙂
Kevin, I've already have seen the later RUclips where you used the thread addon to FreeCAD. How about doing an update to this RUclips using the thread addon? I think that this is certainly the easier way to do it. Thanks for the FreeCAD videos -- you certainly explain the concepts so well. Happy Holidays to you. 73's WD6FIE
You might have me confused with somebody else. I have not used the hole function with threads in a video.
In fact the whole reason for this video was that the built-in thread functionality did not have a match to these pipe threads here in the US. So I had to do them custom.
TY Kevin
Terrific!
I hope you can find the time to present more videos about how to do things in FreeCad Kevin. TinkerCad is just not making the cut anymore. The tutorials I've downloaded for FreeCad don't go into as much detail as needed to actually make the transition from my head to the printer bed. What do you think about the Ondsel ES app that overlays FreeCad to supposedly give FreeCad more drawing options? Anyway, the beginning of this video with the procedure instruction is worth it's weight in at least two E.F. Johnson transmitter desks with the built in Amplifiers. (Remember those?)
I was playing around with Ondsel for a little while, but it crashed on me a bunch of times. I lost work. The free CAD release candidate has been stable not a single crash. An occasional odd error, but they're squashing those bugs quickly almost week to week.
There is another RUclips channel called Mango jelly that I've been learning off of. He has excellent freeCAD tutorials that work at a pretty good pace. Just search RUclips for mango jelly and freecad.
OOOHHHH Fancy smancy new opening!!
Actually it's quite old. I made that many years ago when I had that mini 3D printer. I just dug it up to use for this 3D printing video. I'm going to make a new one, a specific opening for 3D printing and CAD videos. But I guess that one will do for now.
@@loughkb I've been with you quite a while. Never saw it. Must have been shortly before I started with you. You where still in the house when I started watching. I remember when you brought the motor-home. I think I became a Patreon right about that time.
Great video, I would have done it the same way except for the metric. The threads taper at 1 degree 47 minutes.
I thought it had just the right amount of detail.
Well done, Kevin. 73, de N2PPP
Eheheh! Cool intro. Nice idea. 73.
Sweet
1/2"-NPT thread
FreeCad rules ;)
Aren't PVC threads simply NPT pipe threads??
Yes
Nice job. Just wanted to let you know about HEIGHT not HEIGHTH.
Have a great day.

This is a GREAT tutorial, except that very little of it looks or acts the same in version 0.21.2 for Mac OS. It all makes sense, but the toolbars are totally different, some of the tools don't even exist, or have different names (the Dimension tool). Clicking on various icons and buttons opens totally different windows. Various behaviors don't work as expected. For instance, to constrain a circle's center to the origin, I had to first move it off the origin. Clicking on a face does not allow for creating a new sketch on it. The list goes on and on, and as a new user, it's difficult to tell if my version has so many bugs, or if many of the demo videos have heavily customized the app, or if it just behaves so differently between versions and operating systems. Even after making customizations, it is extremely frustrating spending hours only to realize that FreeCAD is not intuitive and has very little consistency. And this is from someone who has used other CAD and 3D modeling tools. Again, this video is great, and the workflow even makes sense, but unfortunately I am unable to duplicate many of these steps. I may try the Windows version to see if there is any difference, but sometimes I guess you just want software that works fast and elegantly and intuitively, and has some consistency between versions, layouts, workflows, naming, etc.
Yeah you need to get the newer version. I believe I pointed out in the video I was using 1.0 release candidate 2 . If you go to the free CAD page somewhere down in the middle there is a link to get the release candidates. And I believe the Mac version is there too. Search for version 1.0 RC2 or later.
EDIT: I just went there and checked and yes 1.0 RC2 is available for Mac. Here's the link to the download page.

This is tutorial I was looking for. Thanks! Best 73 de YT9TP
