FreeCAD 0.20 For Beginners | 7 | Revolve and Sweep for More Complex Modelling | Part Design
HTML-код
- Опубликовано: 6 июл 2022
- In part 7 of the total beginners course to FreeCAD 0.20 we learn how to create more complex objects easily with the revolve and sweep workflows to create control dials such as a cooker control knob. This will be the start of a number of tutorials that teach the fundamentals and practice examples of these operation in both the part design and part workbench where we start to learn why we would use on over the other.
In this course we teach the fundamentals of freeCAD using the basics but delivering via teaching you different workflows.
Our aim to teach you freeCAD in a practical way.

As someone who studied drafting back in high school, I always found it difficult to transition to CAD software. Initially the cost, and secondly learning the tool paradigm.
FreeCAD and your tutorials have really opened my options for the future. Thank you.
Great to hear, glad these have helped you. 😊👍
We had AutoCAD. Mid nineties. The teacher introduced one student to it and they taught the next student, and so on. It is amazing how teaching a subject helps reinforce it for yourself. I was offered, and did use, DataCAD (CadKey, iirc).
jeez , it's so easy once you know how it's done. I would have struggled for ages trying to make something like that without watching this lol cheers mate !
It's one of the reasons why I share this stuff, great that your enjoying 😁👍 lots more to come
watched a few of your videos - you are saving me a lot of time I would have spent on figuring out stuff. your explanations contain just the right amount of detail for me and i like that you go through different options of doing things while pointing out the differences and thus suggesting what is used best for which task. making videos consumes a lot of time so thank you very much for all the effort. keep up the good work and I wish you much more subscriptions - you would really deserve that.
Thank you for such kind words and donation. I really appreciate feedback like viewers like yourself have given and I always try to feed this back into my videos if anything needs adjustment or something is not working. Without knowing I don't grow and improve myself. Thank you once again and it's great to see your progressing.
I never thought i will ever design something on computer but with your tutorials it looks so simple. wow!!!
Happy to hear that! Thank you for the kind words 😊
It’s a testament to a person’s skill when they can make something complex look easy.
I started watching your vidoes about 2 months now and i have to say thank you! I feel pretty good about myself to be able to a few things now and i couldnt done it with out your video's!
Great to hear, freecad has a steep learning curve because of the flexibility it allows through all the different workbenches. Once you start understanding how those workbenches work together things get easier. Welcome to the journey 😁👍
Another powerful tool in the tool box thanks again 😀
Amazing tutorial. Thank you!
Another excellent video. Thank you!
Another amazing video. Thank you so much.
Great video. Thanks again.
great tutorials
hello mr l want to give you congratulation for this work it is ecxelend sorry about my enghlish l am from greece best regards thank you
Very good tutorial series,
As a newbie with a little Blender experience your videos are easy to follow.
And i've already 3d printed some of my designs from FreeCAD.
That's great to hear that you're progressing so quickly, thank you for the kind comment. 👍👍

fixed toilet flush
created mounts for `outdoor solar leds`
designed my own led lamp, with power switch and potentiometer ...
Thanks bro ;)
Great for my learning. Thank you so much :)
👍👍👍😁
Amazing video!
Thanks! :)
Thank you
Love these video, great tutorial
Thank you 👍😁
For a second there I thought you were drawing a modern version of the helmet Marvin the Martian wears.
Lol!!! But it might be worth modeling the q36 space modulator. (thank you for bringing back the memories)
I'm using Rev0.21. For the life of me I can't seem to configure the settings so the 'Edit Controls' box is visible. I finally found the drop down box where Auto Constraints/Avoid Redundant Auto Constraints can be checked. But this must me one of those 'intuitive' things. That's where software updates hide things that take forever to find. Unfortunately I haven't used this software enough to consider myself a native user like I am with AutoCAD. I was using that back in the DOS era.
Thanks😄😄😄
👍👍👍
Thanks a lot for your work its really amazing I am learning a lot. However I am having an issue in this example. After I connect the two profiles using the additive pipe it looks great. But either the "revolution(Knob)" is visible, or the pipe is visible... I can't display both at the same time..?
Great, I am about to make a knob for my car clutch handle, preferably with the car logo or the gear scheme on top
Now that's a pretty cool little project 😁
@@MangoJellySolutions yes, it also has an internal M12 thread to screw it on the lever. I am not sure I can pull it off as I have invested a lot of time into Blender which gives me other possibilities for other kinds of projects. But I am trying to keep in touch with FreeCad by regularly watching your videos as its an awesome program to make objects that can be printed correctly. In other words: maybe you like to make a video on it?
I wish you had covered making the D shape for the knob.
New Sub!
I am new to FC and appreciate these courses.
At 22:25 when you created the second profile, would it have been possible to copy the first profile and past it in place of the second profile, then change it’s dimensions ?
Welcome to the channel 😊. To answer your question yes you are correct. This could be done in a number of ways (as usual with CAD packages, a hundred and one ways to do the same thing) so you could do one of the following: draft wb clone and modify the scale, part design sub shape binder and offset, sketch carbon copy and tweak the sketch. There are probably a number I have missed but that gives you a few. Each have their advantages and disadvantages.
23:36, can't you use a fillet on that edge to smooth out the transition?
how do the bowling pin image got background removed when sketcher was selected?
Isn't it important to get fully constrained sketch before we close the sketch window?
It's important but not essential. I normally do in modeling but to keep the lessons a little shorter I sometimes skip over this for some demonstrations.
How would you repeat a profile pattern along a pipe / path? I want to produce a Tesla valve.
Hard to describe. A repeating revolve maybe?
As a fan of tesla (and Esher) I was thinking about doing a video about modelling some of his inventios, I forgot about this one. Each valve could be repeated in seperate whole sections and joined together as clones so you build the section as one and then boolean them together.
Hi, I am trying to create a 2metre long curve but when i use the additive pipe tool it only creates a small piece of pipe at each end of the path. Any idea why?
how do we make a " D " shaped pocket ?
If you select the top face of where you want the pocket and create a arc and close it with a line then this will create the D your looking for, from there you can pocket the shape.
Tried several times. Could not get the dial indicator to come out. Does not merge into the profile of the smaller tab. Also, I could not draw the second tab correctly on the proper face. my XY plane was at the end of the cone and I had to move it back to the proper plane. I'm sure they are related, but I'm stymied at this point.
Hi How do you have a cut in the shaft , not all shafts are circular , some have half circle cut ?
You can use an additional sketch and pocket on the base of the shaft so you can pocket in an shape you like such as a D shaped sketch.
@@MangoJellySolutions : Thank you for the response , let me try ! thank you again.
I prefer the first way... my imagination is limited
Out of curiosity, why not use the cross-section rather than redrawing it? I cheated, retaining the cross-section and using it to create the new sketch, which seemed to work perfectly. One difference between my project and yours - the Revolve was created outside the body rather than within it. The sketch I created is within the body and the body was active when I did the rotation. Perhaps this is because I'm using 0.20.1 rather than 0.20?
I revisited this again today, and did it exactly the same as you did, deleting the cross-section and redrawing by hand. The result was the same; my Revolve was created outside the body. The only difference is that I'm using 0.20.1 and you're using 0.20, so that seems to be it.
I'm not sure how that's happening. Revolves in part design should always be in a body as they are automatically fused to your main body. Do you have the file at all that you could send me? Its a real strange one. Is the sketch inside the body when you start?
@@MangoJellySolutions When you look at the file, you'll see a number of ReferenceRevolve's. I think I had to do this because the initial revolve isn't in the body.
Strangely, I didn't have to do this in my first attempt (in which I used the cross-section rather than drawing the sketch from scratch) even though the Revolve wasn't in the body in that project either.
I love freecad, but it's frustrating to edit a chain of attached objects. If there are ANY changes in a sketch at the top (even a simple movement or dimensional re-constraint), it can often break downstream attachments despite the same surfaces existing.
I spend most of my time trying to avoid this with a careful use of a scaffolding datum planes and sketches (rather than attachment to surfaces), and editing breaks when editing an upstream feature.
A bit more consistency would be a god-send.
2nd tutorial vid I'm watching to revolve a simple rectangle around the Z-axis, and nothing works.
My sketch is fully defined. It will only sweep it around the X-axis, no matter what I do. Any other choice and there's just nothing.
IDK what I've missed, but these vids seem to take something for granted that I can't figure out.
There are some troubleshooting tips around 11:08. Hope this helps.
Odd question. Are you left-handed? I always sketch my revolves on the right. Of course, it doesn't matter, just curious.
I don't know about Mango Jelly, but I'm right handed and seem to have fallen into sketching my revolves on the left. I assumed that the reason why is I read left to right, but it might just be based on where one started learning revolves and got familiar doing them.
No I'm right handed, just the way I was taught during CAD training all those years back.
Seeing someone casually adding sketches to faces is confusing when all of the other tutorials I watched so far told me to avoid this unter all circumstances … 😆
It's not something to avoid, it's something to be aware of as you can go back and fix the problems. It is defacto CAD practice which I follow in the videos. The problems what people talk about is the TNP issue. But, not all problems are TNP and it often it gets miss diagnosed. In any package if you delete a face / edge you will get an error if you anything attracted to it and you will have to reattach the sketch / geometry. But with Freecad we have the additional issue of faces sometimes being renamed after a change which in near future releases this is going to be fixed. Attaching to faces is usual practices. You be missing out most of the CAD world if you try to avoid it.

I have no idea, have you checked your youtube settings. I have never heard of this before
