I don't even care about the details of a FreeCAD tutorial atm - I'm adding likes to anything which helps people cross deck from Fusion 360 and gets more momentum into FreeCAD. I hugely value this channel for helping me learn FreeCAD and it deserves attention.
I'm loving it but cant get the install right. If there was some generic install clone for each major OS, that resides wholly on your HD that would do a lot.
The lack of dimension mirroring definitely threw me off the first time I used this. I find it so strange that I mirror something and it doesn't stay linked to the original.
Computer fan in freecad? Still new to cad I had a go at just the blades/hub got pretty much the shape I was looking for which is really cool(the compressor videos helped a ton) it feels like I could be much faster! I know practice will make it happen though any tips would be greatly appreciated!
Wow this is awesome. I guess doing custom helical gears wont be a problem with FreeCAD. Does anone have an idea where to start with organic shapes in FreeCAD? I have to print sun visor pivot trim cap for r129 mercedes and ohnestly I thought about scanning it and importing stl for a template. Nothing else comes to mind :/.
Thank you for this tutorial, actually I've learned to make this lobe from your solidworks tutorial, and I able to do it on freecad, but my problem is (which still there) how to design those real-world lobe which mostly not identical. I've not able to find any tutorial or paper to learn it.
Another possibility is to use the array add-on. You can make an array of a number of profiles and then loft trough them. This doesn't have the variable twist problem. I used this once to try to make a globoid worm gear, but didn't succeed.
Yes but I don't know exactly what you mean by spiral. Some people have asked me about spirals meaning a tapered helix; which at 9:22 you can see the bounding sketches I made. You could probably angle those to make a 'conical' tapered helix. If spiral here means a shape that is widening around a curve in 2D space, you can go into the part workbench and insert a spiral from the geometric primitives and use the spiral as a sweep path.

Agreed

First comment! The world is a better place with more superchargers.
I sincerely appreciate the video. Now that we can draw them, we just need to know how to animate them! Thank you as always.
It always amazes me how much stuff you can do in FreeCad
Thanks for sharing these skills. :)
You say "supercharger lobe", I say "liquorice". 😜 Brilliant tutorial!
funny Gear set design, thanks for share, it's be a new "homework" for me.

Sht hot man, thanks!

How do you calculate dimensions of supercharger crews?
After reading your title, I thought you will design something that charges Teslas or so :-D Didn't knew that this thing's name is so...

These FreeCAD options get very esoteric sometimes. How does the "freenet= true" fixes the twist? Why?
It's actually frenet, named after Jean Frédéric Frenet. Check "Surface modeling. Part2 " on the Opencascade blog for pic examples.
👍 I see you are using version 0.18. Is there a particular reason you are not using version 0.19_pre? Just guessing, OS restricted maybe? TiA. 😃
Is there any possibility of spiral sweep of any shape in freecad?
Yes but I don't know exactly what you mean by spiral. Some people have asked me about spirals meaning a tapered helix; which at 9:22 you can see the bounding sketches I made.
