Cylinder head - Months in the Making

[Celica_Supra]

Hopefully you'll see I use the symmetry constraint a lot later on - Sometimes I'm still thinking in terms of other platforms and forget about the symmetry constraint and how much time it saves.

I had seen that you used symmetry before, so this was rather a comment for others who take it as instructional video.

Got it! Thanks. Its a fantastic constraint and once I got used to it, I find myself wishing I could use it in SolidWorks. I think it's one of the great intuitive things FreeCAD offers.

Hello,

First of all great tutorial and model.
A question though. Not to you actually but to main developers.

The Extrusions are not automatically merging to the intersecting faces which are creating separated faces. Shall there be a bug issue about it, or enhancement or something ?

I could not really find it but there is a Line Edge somewhere with 1 vertex(it should have been).

Again great model, but to make freecad better these things should have been healed

Is that a honda DOHC cylinder head?

There is nothing to be healed, but you can set the Refine property of the last operation to true to get rid of the coplanar seams.

It's a nothing head

On a real vehicle, I would expect the inlet to bifurcate inside the head, not have a separate inlet for each value. Also inlet would be larger than outlet. But in view of the work this was I can fully understand the cheat of four identical valves. Also the b-spline makes a nice looking combustion chamber that is an art in itself.

Anyway great video, I learnt a lot about FreeCAD by watching it.

You're absolutely right, I'm embarrassed I missed that
