FreeCAD: Sketcher: Template sketch from external files for repeated geometry. Link and Shape Binder
HTML-код
- Опубликовано: 25 авг 2024
- We learn how to create and use an external sketch created in freeCAD. We will create and save our sketch to a separate file and learn how we can reference this in our project as a repeatable geometry such as logos, branding or geometry that you use over and over again. The sketch will live in an external sketch and we will learn how to make use of the link and shape binder tools to link this into our main project and also allow for any future updates to the template sketch to take effect in our main project.

This whole idea of a sketch library is what I have been looking for, for a while. I think it is great!
Glad it's helped 😊
You absolute superstar!
I've been trying to link to a sketch library all day. Google wasn't very useful. I got bogged down in bug reports and developer discussions (the error messages aren't particularly helpful). There are plenty of youtubers doing freecad tutorials but none of what I found demonstrated this relatively simple but absolutely essential concept.
In case you are interested, the sketch I am trying to reuse is the profile of the aluminium extrusions used in my 3d printer. It's always the same but it appears in many parts of different length.
Thanks again, instant sub :-)
Fantastic news that my video helped, really appreciate the detailed comment. I always use comments for research to create more videos. Nice to know what you're duplicating each time as well. Always good to know what people are using the video for. Gives me more ideas and guidance at what to tackle. Thank you again.
Another extremely useful tutorial! Thank you for creating top notch tutorials for those of us looking for open source tools! 🙏
Thank you for such kind comments.
Quck tip: In case you are using sketches as the foundation of your new bodies and you DON'T want the binder to create faces, select 'false' in the Make Face option (Data tab in the Binder Property).
Thank you so much for this tutorial. Subbed!
Thank you for this, it's great that people share this information with others that may watch this video. Always appreciated. Thank you for the comment and the sub 👍
@@MangoJellySolutions No problemo!
well done - thank you!
This is exactly what I needed! Thank you. Could you make a full tutorial on multibody design workflow? I come from an inventor/solidworks background where every real world part needs to be a separate body in the cad model for CNC programing to be possible (e.g. table legs, cabinet doors, ...). The idea in freecad (I think) is to create a part file as the container, then for every real world part create a body with sketches and needed features (e.g. a model of a table would have one part containing a body for each leg and the table top, so 5 separate bodies). After the model is done, open an assembly work bench and separate each body into a part, assemble the parts into the table again and begin the process of CNC programing for each of the parts/bodies (sawing, milling, drilling, ...). This video in particular could be the key to the needed workflow since most tutorials focus on single body design (what should often really be multibody) and that approach is pretty much useless outside 3D printing.
Hi, thank you for the comments and glad you liked. I am currently 1 video away of completion of a multi-body work flow at the moment where I am creating a Piston and crank shaft assembly using part design and a2 plus wb. It also uses a master sketch. This is currently on my channel and will give you an idea of the workflow. Its part of the understanding freecad series that I am running. There are 4 videos in lesson 3 but you will only need the first 3 as the last one is about scripting an animation with the wb. I am looking to do more generic ones around this workflow in the very near future.
You just made my day!
Thanks!
Thank you so much 😁👍
Another excellent video!
Thank you 😊
Thanks...
Wow thanks
Thanks for the videos. Very useful! If I want to change the sketch without altering the original how would that be done?
So, how to have a parametric sketch (or a part made from one, for that matter) in one file, and then link it twice, so that one can change the parameters of the one link to one thing, and the parameters of the other to something else. E.g. I have a panel (cube) that is sized like .length, .width and .thickness, include it twice, and be able to have one link sized 4x5x1, and the other 5x4x2 for example?
The only thing that worries me about external links is reliability of pointing to the right location...
For example what happens if you switch between Linux and Windows (I use both)
Can you edit link address?
Otherwise great video (as usual 😉) - thank you 👍
Thanks for the comments, glad you're enjoying the videos. There is a link pointing to the file on the data tab but I have never changed it. I would assume you can. Next time I will have a look as I am now wondering if you can just give it the filename rather than the full path so it would look in the same location as the project file allowing, maybe, to just lift the directory and place it in another location. This is the reason why I love people commenting on the channel and the videos, really makes you think about what else you can do with the software.
It would be great to have the ability to add a model too. Things like a hinge or latch for a variety of projects so one does not have to recreate them on every different container.
Sorry missed your comment. You can do this with link in the same way, even down to the part design action like a fillet. Nice application you suggest there, always handy to have an real world example.
Thank you for this 🙂
What's the advantage of using a link here? You could also use the binder directly on the original sketch.
Also: it doesn't work for when trying to build on top of this with a second imported sketch 😢 the first sketch I import is used to pad, then I want to do a pocket with the second imported sketch but it fails... Any ideas why?
I've been looking for this for a few days now, thanks for the great tutorial.
I have a question. The template sketch is in XY plane. If I want to use it on the surface of a body which is in XZ plane, how should I do that?
Thanks for the comment glad you like. You should be able to use the sketch menu option for reorient in a different plane to adjust the sketch.
