FreeCAD- Methods For Even More Surface Control |JOKO ENGINEERING|

[@brucewilliams6292]

Thank you so much for the cool cad demonstration. Your daughter crying in the background brings back what are now very fond memories. They grow up wayyyyyy to quick.

[@JokoEngineeringhelp]

Thanks. We had her first birthday yesterday. It seems the moments go slow but the time goes fast.

[@checkavilatility]

I really appreciate all of your work. Thank you for making FreeCAD more accessible to others!

[@magneticartist]

wow FreeCad getting organic I love it. Great tutorial Joko. Very well made. combined with the power of sketches makes a great complement. sketches are like the splines and vertices functionality in 3dsmax and blender but with the added benefits of engineering constraints. Thank you.

[@BTom16]

I really appreciate your videos. Thank you.

[@Miniellipse]

Great teaching style. Thank you for sharing with the world.

[@IanSGI]

Great tutorial. I thought the first portion was great, and then you added even more depth with the curve surface and my head exploded. It was really good to see you show the concept once, and then almost repeat it exactly but with a little more detail. It really cements the process.

[@liquid-stoe]

Amazing, never used this workbench but it seems really nice for making more organic stuff, great video thanks !

[@hermansnijders1080]

NICE! Thank you for ALL your great tutorials! 👍👍👍

Very helpful. Many thanks for sharing.

Nice shifter!

You are the best.

[@williwuchtig3336]

It was impressive, thank you very much.

[@ryansisak6144]

Hey Joko, Thanks for the video. I was wondering how to fully dimension a spline based on points on the curve? In most other CAD softwares I used, the spline is created by points on the curve, however FreeCad defines the curve based on control points. This makes it difficult to follow drawings that call out splines. Maybe you can address this in a future video? Anyways, thanks for the vids!

[@MrLarry0001]

Thank you very much for the videos. I've learned a lot from watching them. I'm curious how to make a grip similar to this but only half of it, such as left and right grip panels (like in my video "DIY Pistol Grips"). Will the "curved shapes" application work with a shape that is not symmetrical? I've tried a few different things and have had no success so far. I end up with errors or really weird shapes that do not resemble any thing that I have drawn. I've been making pistol grips for years out of wood, but thought I'd try 3D printing grips for more modern pistols. However, I want to get CAD down before I purchase the printer. Thanks again.

[@sim-racing2277]

Thank you. Gotta say, finding this software tediously unfriendly for even basic stuff that can be done in seconds with Tinkercad!

[@jimstack2031]

Thanks for all of your tutorials. I thought I was coming along pretty well with FreeCAD before, but I've learned a lot of great things through your videos. Is there a reason you didn't choose to make the two halves solid and then union them together rather than creating the surfaces and using those to slice out from the box?

[@JokoEngineeringhelp]

I was helping a person who had emailed me and that method was good for the context of their needs. I think your suggestion would work splendidly

[@musolo78]

Wonder if you could continue with this tutorials and make it in into a flight stick grip tutorial that would consist of 3 parts and would be hollow inside. I`m trying to learn how to design flight grip for a prototype of the joystick for 3d printing. And couldn`t find any tutorials of similar nature. Thanks a lot for your lessons!

[@JokoEngineeringhelp]

Interesting suggestion. This should hallow out well if you go to part>thickness, select the top face and perhaps the bottom face and specify a thickness less than the minimum radius on the part.

[@mt221174]

It works, thank you. I've tried several shapes and it works. But what if the ending shape is different from the biginning? E.G. i start with oval end finish with circle

[@JokoEngineeringhelp]

It's been a long time since I put this out so I'm trying to recall everything I did. Using the curved shapes workbench, you're limited to the initial sketch. I would suggest the surfacing workbench for other tools that would work the way you mention above; I make a mouse and guitar in another videos and perhaps some of those workflows are in line with what you would need.

[@ArdoBewokFishing]

what differencies between Curves Workbench & Curved Shaped Workbench?

[@JokoEngineeringhelp]

Curves Workbench is designed for general surfacing, curves shapes is designed by someone who wanted to make wings and air foils easily, but is useful for a lot of organic shapes

[@cezariuszczapinski9428]

Great tutorial, thanks a lot. I wonder if it is possible to do knurling on the sides of the handle ? All FC knurling tutorials I've found so far show only round object knurling.

[@JokoEngineeringhelp]

SolidWorks has some functionality to do that, if it's not available in FreeCAD it probably will be soon

[@JokoEngineeringhelp]

Thinking about it a little more, you could probably cut a knurl pattern in a surface and thicken the surface, merge with solid

[@cezariuszczapinski9428]

@@JokoEngineeringhelp Thanks for the answer, I used a bit different approach - using angled sections as sweep patch (120 of them) and a little triangle to cut knurling pattern. The only problem is that it's a very heavy workflow for my rig :/ This is imported step file, so you can take a look at it if it is possible with your workflow, the grip is KG13 one : drive.google.com/file/d/1dHk5rzxlwjcO5TkuuYEZ1lqRSxzZLzHB/view?usp=sharing I just finished knurling path with sections and it looks bad at the front/back of the grip: postimg.cc/svh4t9Xn After a week of Blender tutorials I did something that looks acceptable to my standards : i.postimg.cc/bwQr3t3j/kg13-knurling.png

[@JustinDeane222]

@@cezariuszczapinski9428 can that blender model be 3D printed? Is that knurling a material?

[@cezariuszczapinski9428]

@@JustinDeane222 Hi, this is knurling is a mesh, so if you print the handle it will be like on the real Bf-109 ;-)

[@eg2580]

Thanks for the video, I want to make myself a joystick for flight simulator, while i have some experience with simple objects in freecad, i can't make anything with curves, now i can! Is there any impact from not fully constraining the bspline lines?

[@JokoEngineeringhelp]

Often I don't constrain them depending on the design intent. If the curvature is critical or needs to be precise in some way, fully constraining is best practice

[@eg2580]

@@JokoEngineeringhelp awesome, thanks for the reply! I find them messy to constrain, so would be happy to leave them.

[@kebatekmusic2705]

I can't use the Sketcher/External Geometry tool for a pick a dot (juste for line), please help

[@bengerber4542]

Whenever I try this tutorial, the curved shape workbench gives me full ovals instead of half ovals, so the oval center is halfway between the front b-spline and the middle curves and creates a closed shape. The only solution I can find is doing the curves across the entire front, middle, and back items and then slice it apart in the part workbench...

[@pavelkalinine]

Please advise how can I use existent curved surface of the imported model to inherit geometry? Thank you.

[@JokoEngineeringhelp]

Try the method I use with the mouse but instead of the surface I make, use the imported surface kzbin.info/www/bejne/j6rJl6hmmb5rnMU

[@De4dB33f]

The distortion you get on front bottom part while creating surface is because front line is not connected to the base, there is a gap, this could bee seen here, when you zoom in =) kzbin.info/www/bejne/j6myfYKrr7SKbLc

My man just flexxed at me with his supra in the middle of his tutorial 😂 mk3 or mk4?🤔

Mine is an MK2!

Bob Ross?

[@GrantSR]

Just so you know, it is literally impossible to watch where you are clicking with the mouse AND watch your little gadget on the screen to see what modifier keys you are pressing. It is always much better to call out the modifier keys and hotkeys you are using verbally. This is just how human brains work.

[@EngineeringFun]

Those two vertical lines should have been tilted, probably 15 degrees. Right now, you ended up with unbalanced curvatures along the height of the part especially on the top and bottom.Also you should have shown how to do the lettering. Otherwise a helpful tutorial. Thanks.
