FreeCAD: Model curved objects: Spoon in the part workbench (Easy, beginners tutorial)
HTML-код
- Опубликовано: 20 авг 2024
- How to model curved objects such as a spoon in the part workbench in FreeCAD using a loft as a cutting tool to create the spoon from a series of simple side and top profiles of the spoon. This technique allows you to create curved objects with ease. The profile will be created via the sketcher workbench and the extrude and lofting will be done via the part workbench to create the shape to split the extrude apart. With a single boolean operation we will then create the spoon.

again, a clever solution with basic steps! thank you
Thank you 👍
There is a workaround to get the tangency constraint which comes from the definition of the B spline.
Bezier curves (B splines) are guaranteed to be tangent at the end points with a line connecting the end point to the previous/next control point by their definition.
You can leverage that and create a construction line between an end point and the adjacent control point and then apply tangency constraint to that control line with anything you want, which will guarantee that your B spline is tangent to the thing you want at the end of it.
Thank you for sharing that tips, and helping others out with adding to the comments. It's great when viewers contribute their knowledge and ideas. Really appreciate that. :) :)
Very impressive...and useful as usual...Thank you so much!!!
Thank you for that, glad you like
Super great share, not sure I can master these useful techniques further than just copying what you do. There was one last slice I thought you would do to make the rim of the spoon planer I think in the x-y plane.
Great tutorial!
Thanks for detailed and informative video.
I love the tutorials! Definitely stretching me :-) I feel like I should be able to do a mockup of an America's Cup AC75 boat, at least the hull but am having problems. I would love to see a tutorial on how to make a 3d hull surface. thanks again for all of the tutorials they are great. 😀😃
Glad you enjoyed. There are some tutorials on my channel relating to boat building by lofting cross Sections which may be able to help you.
look forward to seeing how you do it in part design, please 👍
I meant to say curves workbench but going to do both now 😁👍
Well done. I can see this an elegant method to create rc plane canopies.
Thanks for the comments and the application you would use this for. Great to hear. Just to let you know I have created a video regarding your question about offsetting the profiles so they don't see the seam / faces when 3D printing, I think it was yourself that asked for it. And also going to be creating a video regarding cross sections and creating the slots for attachments allowing for profiles and supports to lock together (not sure if this was yourself) but considering you are into the RC plane building it may be useful for you so adapt for your needs.
@@MangoJellySolutions thanks for remembering. I did make the first request, but not the second. In any case, if it is useful for designing 3d printed RC planes, I’m always interested. 🛫💺
Thanks! I really like you videos!
Thanks, nice to hear 👍
It's almost magic.
Very helpful! Thank you
Following this as a guide, I'll try to make a fork. Or maybe, a spork (much easier).
Good luck, if you manage please share a image if you can on twitter and tag me, I love seeing people's progress.
Very useful thanks!
thanks so mutch :)
great tutorial, i think in blender this would be way faster and easier to do.
wonderful :)
Thank you
Thanks for the tutorial. It may be easy for you but I had to go back and delete a few times for to get it to work right. I could not get my tessellation deviation lower than 0.23 in FreeCAD ver21.1 as after that it produces a thin vertical face along the spoon handle on the Y minus side
The second variation that you taught and then I could achieve the 0.1 deviation w/o a problem. My spoon looks like a dangerous weapon though.
It is the easy way to create a spoon
whats the other way
Thanks very much. The tutorials are great.
I do have a question. By sketching only half of the spoon you create a point at both ends. That you use as a reference point later on. Can you do the same if you sketch the whole spoon? In other words can you make a reference point to a (part of a) circle, line, arc and use constrain coincident? Thanks very much.
Great to hear your liking the tutorials. So there are two ways of making such point. There is a split tool in the sketcher which adds another point but you would have to add additional constraints as you now have two pieces of geometry linked together. Or you can use the sketcher point. The point is automatically placed as construction geometry but by clicking on the point and clicking on the construction geometry tool it will be changed out of construction mode and show up as a vertex when you exit the sketch allowing you to reference in other sketches.
Thanks very much. 1 month ago I never ever used any kind of 3D program. Thanks to your tutorials I'm making a start. I watched part 1 and 2 a dozen times, over and over again. That helps!! I will continue watching the other video's and hope to learn a lot (even older woman are not lost :) ).
@@marinajonxis2393 It's great to hear your journey and I am so pleased that I am starting to reach more Gentlewomen now the channel is getting a bit of traction. It's a small percentage but it's starting to build :)
I have been trying to get my shape to highlight after making the loft but it will not highlight and i cannot move bottom half of spoon shape with the transform function. Not sure what I am doing wrong.
Love your tuts.
But why do you say "If we so desire" so very much?
I thought about using "as you wish" but it has already been taken by Princess Bride 😁
@@MangoJellySolutions I know its not easy narrating for over 20 mins of footage. I have watched quite a few of your great tutorials and just thought I would be a RUclips commenter asshole for once.
@@DirtyRobot lol you can be my official troll if you like 😆 . Glad you like the videos :)
I have a problem with freecad curves workbench. When I select curves workbench an error appears: "invalid syntax (process. py, line 262)"
Try updating the workbench from the add on mannager.
