Understanding FreeCAD: Lesson 6 Shape Binder Hinged Box | Part Design Beginners Tutorial 3D Printing
ฝัง
- เผยแพร่เมื่อ 4 ม.ค. 2022
- In this lesson we learn how to model a a hinged non symmetrical box for 3D printing using the part design in FreeCAD. Using multi-body modelling we learn how to use a sub-shape binder to reference parts from one body in another, allowing us to pull geometry such as faces, sketches etc across bodies to build parametric features. We will learn how to use a linear pattern to create the hinges and reference these in another body to create a inter locking set. We will build the box with basic partdesign wb features so as pads and sketches from the sketcher and learn how to hollow out these features with thickness to create walls to our box. Built in a beginners friendly way so if your just starting out with FreeCAD then you will be able to follow this tutorial.

Thanks a lot. I at last got how to use shape binder properly. 1000K of kudos to you !
he is a really good instructor. yep
this series is better than what's on Netflix these days
Lol, thank you 😂👍
I needed some nice practice,but no idea. And you are offering a good one as always ! thanks!
Thank you, great to hear 👍
That was quite a useful video, thanks.
Thanks. Finally a shape binder tutorial with a real model to follow along to see where this features shines and not just random sketches and bodies thrown together. 👍
Thank you for the feedback, glad you found it useful
Thanks for the video. I'm slowly training my brain to think in Freecad and your videos have been a great help.
Thank you for the feedback, great to hear. Freecad has a steep learning curve, you have done well to come this far.
@@MangoJellySolutions It does, CAD in general requires you to get some unintuitive concepts straight in your head. I blame this on the tendency to try to write reverse engineered applications with legacy in mind. by that I mean they do it so someone who is already trained in one CAD program has familiar concepts to rely on if they start using the new application. In my opinion however this is a bad idea. One promoted by Corporations that don't winch to have to pay for full 100% expensive training hen they hire new people that have experience, but on a different software. The ultimate I know it doesn't make sense but that the way it is done argument, lol.
Prime example of that is everone's need to constantly explain the strange and unintuitive ways to link geometries from one sketch to another. in a ideal environment all you would have to do is ctrl-Click a master sketch and drag it into a body to use it as a direct linkable reference. Making a referenced copy. a plus would be to hide the sketch in the root folder (or fix the fact that the master sketch is on top in the layers hiding the local one underneath, duh). If legacy training was ignored, then new Cad software would be Much Much Much easier to learn.
This is the video I needed to get me over the hump. Being able to reference other parts is a game changer for me.
Spreadsheets were getting way too unwieldy for me.
Thank you for making this. I donated a few bucks to your channel as thanks.
Thank you for the feedback, glad it's helped you. Spreadsheets are good when you have more complex geometry but as you have found can get unmanageable. Thank you so much for your donation 👍👍👍👍
I have to keep going back because of mistakes, but getting there. One hell of a usefull tutorial. Thankyou very much for taking the time to teach us. 👋
Glad your learning, just take your time and you will get there. Thank you for your comment.
When using a link to another sketch as a master sketch (as a construction line source) it would be nice if all u had to do is ctrl-click the master sketch in the tree and drag it to the body you want to use it in (automatically hiding the master sketch). Simple and intuitive.
Thanks for the awesome tutorial! Helped me a lot in understanding shape-bindings.
Great to hear its helped you, glad you enjoyed
Wow, lots to learn from this video. I am quite new to FC. The info here will save me a huge amount of time. Thanks!
Great to hear your finding them useful.
Great tutorial mate
As usual.
Thank you 👍
Thanks for that 😁👍
I'd give you 3 🖒 thank you so much for your time and effort. This has helped me tremendously in my projects. I'm passed 30 and got into FeeCad in December 2021.
Great to hear and thank you 😁👍 it's great to hear more and more people are coming to freecad. Enjoy your journey
Great tutorial! So many others do not tell you all the keypresses they are making along the way, making them almost useless.
Thank you, glad you enjoyed. I try to keep to the icons and menu as much as possible but the odd key combination I will use but not many. I have sat through blender tutorials and they are just frightening when it comes to key combo's
This series has been very helpful! You videos have a good order to them. Happy New Years!
Happy New Year Bruce, thank you once again for the support and comments. I was wondering about the order so great to hear I'm on the right track.
bellisimo ! and thanks.. clearly explained (wonders how he edits/records it)
Excellent tutorial! Congrats!
So many useful tips!
Thanks for the feedback 👍
Impressive!!! as usual!!! thank you so much! I have thought I would review the part design workbench...and in fact, I have learnt a lot of new and useful tricks... Great work!!!
Thank you for the feedback, great to hear you enjoyed and exploring other wb in freecad.
For the hinge shape binder, assuming dynamic referencing is not needed, then it's a lot faster and just as good to go into the inactive BottomBody, select the HingeSketch, then use Edit --> Duplicate selected object. It will automatically place a perfect copy of the completed sketch into the active LidBody, and it will be placed in the exact same position. No muss, no fuss.
So hard or me. Thanks a lot :)
Hi, I am trying to move the lid hinge 10mm so it isn't sat on the bottom box hinge, I used the z plane and moved 10mm, clicked off the picture but the lid hinge didn't move, any idea? 38 mins in. I clicked on update & it moved the 10mm, all good 👍
I am having trouble get the hinge to be free, it keeps(4th attempt)attaching the other faces and does not stand alone, hence I can't move onto the Lid.
Hey , Buddy . learned a lot from this video . My Question / Request is this when you demonstrate threads in an upcoming video . could you please show multi start internal and external threads if possible ?? Thank you for your videos and sharing your time and expertise .
Kindest Regards
Terry Lembke
Glad you enjoying the channel. I will add your request to the list. Thank you. 👍
Thank you, very clear tutorial. Few comments : 1- it will be nice to know your version of freecad. 2- I think some of your work flow will create topological errors if you were to add features to your bottom body.
Agree. Very good tutorial except the hinge creation on the Face instead of a solid reference (plane) should be avoided as this is likely to cause problem down the road. Ask me how I know, leaned the hard way! 😳
@@ericbelanger6900 it is why I think is important to let know every time the problem of using faces with freecad.
Thanks for the feedback. So everything I do at the present time is on 0.19. I don't use RealThunder as of yet as its still in dev though the topological issues have had outstanding progress to remove the issue. With the videos yes there is that problem if you go back and modify faces which is the reason why (which I should of explained) I left the hinges to last. It's a interesting dilemma that I have, I have tried before to be topological safe in my videos which result in comments saying that I should of done it the way that isn't topological safe. At some point these issues will be solved using universal CAD modelling and all will then be fine. Topological issues normally come from changes from the target design. Though I am not using a technical drawing I an working towards a set end result. It's really is a hard when doing these videos to cover without the videos being way too long and people losing interest. I have talked about topological issues in a video before which resulted in me removing the video because of hatred and negative comments towards freecad. You probably understanding my predicament.
@@MangoJellySolutions thank you for the explanation and I agree with you. I worked many cad softwares and found Freecad to be fantastic even with the topologic naming problem. When you know it is easy to work around for me. Thanks for the great video.
@@MangoJellySolutions "...So everything I do at the present time is on 0.19..."
it would still be useful to make it clear. TH-cam is full of FreeCAD videos that are no good to me because they are using different/old/mystery version of FreeCAD.
Otherwise I am enjoying your channel - thank you! (even though I am only using Realthunder's Link branch - it may, in theory be "experimental/in development" but it works great, and I am not missing so called "master" branch at all...)
😃😃😃😃😃
Great content. I really like your work. Shame this one just ignores TNP. Poor users who'll try this and fail. 😕
What about the topological naming issue in FreeCAD? Wouldn’t the model fall apart if a change is made due to placing sketches on faces?
Could be resolved by placing a sketch with the correct offset to the main plane?
Depends on if the faces change that much but yes that will help stop you hitting those issues. This has been asked a few times on the channel. With topological you have to think about the future of freeCAD, at the moment freeCAD has improved around this area especially with link stage 3. At some point this will all be resolved. The tutorials are from the concepts of traditional CAD practices for longevity. Offsetting sketches and attaching them loosely to your models does help but you end up slowing down the process. Being able to go back through and fix these issues as they occur or build large models in smaller sections then you end up managing any issue and also you get a deeper understanding of the dependencies.
At 31:15 and 33:15 and 47:30, why add the extra step of defining an equality instead of just clicking the external geometry that you want to match and linking them that way? You mention specifically doing it this way but don't go much into the "why", especially for the first instance; I'm very curious as I *think* this has always worked okay for me.

I got lost at the use of the sub-object binder... Over my head at this point.
Sorry to hear that. In my learning freecad for beginners series there is a episode devoted that that specific subject which may help.
@@MangoJellySolutions You're the best, don't get me wrong. It may be that it was late and I was fuzzy-minded while watching. I will look for that other video, and thanks...
@@crossthreadaeroindustries8554no problems, trust me it can be a confusing subject until you have done it a couple of times.
@@MangoJellySolutions Whatever I know, I learned from your vids...Thanks!
