Also, don't watch videos on YouTube unless you ENJOY extreme envy:

I have literally no idea how this is even possible.

Lets see, a pipe is a hollow cone plus a cylinder (2 minutes) add some
csg for the red part (another five minutes). Debugging the loop and
passing of parameters (+5) adding a wooden box (1 +6 for selecting the
right texture), getting the viewpoint right (3 minutes).
adding up... something under 15 minutes I would guess. Am I close?

Have you *tried* doing CSG with SketchUp? You don't just say "please
intersect these two things".
First it takes about 10 minutes to try to persuade it to position the
items where you actually ****ing want them. Then you say "intersect",
and all it does is alter the polygon mesh slightly. YOU must then,
manually, delete the faces you don't want any more. One at a time. You
see, any curved surface becomes 25,000 polygons, which you must delete
individually, one at a time.
Just to make things better, I got my CSG slightly wrong anyway, and it
took longer to fix it.
So, now you have one pipe. But I want 23 pipes. So, first select the
pipe and ask SketchUp to make 12 copies of it. (Fortunately, there *is*
an automatic way to do this!) Now select 11 of those copies, and make
them all 5% smaller. Select 10 copies, make them all 5% smaller. Select
9 copies. Make them all 5% smaller. (Are you bored yet?) Eventually, you
have 12 pipes, all different sizes. Now the fun part. Copy them,
reposition the copy. Mirror it. (Do NOT rotate it as I mistakenly did!)
Spent 20 minutes trying to make it line up properly with the existing pipes.
And, yes, stick them in a box, which takes about 45 seconds.
I can't help but feel that POV-Ray could have done this radically
faster. And the pipes would be *real* cylinders, not 24-gon prisms. And
they would be *shiny*!

Yeah, I got that part.
I mean the part where he does something, and he can still edit it
afterwards. Or the way when he moves things, they actually go where
they're supposed to go, and it doesn't destroy the existing model. Or
where he mirrors something, and manages to get the two mirrored copies
to actually line up exactly in all directions. Or the way he draws a
small cut, repeats it 6 times, and it *just happens* that the cut is the
exact right size that exactly 6 copies of it fit in the available space.
I could go on...
Also, I cannot believe that anybody could seriously build something like
this without some kind of reference drawing to work from. It would be
impossibly difficult.
Also, if a normal person tried to do this, they'd spent 6 hours building
part of it, and then realise that it's actually completely out of
proportion, and it's now too late to change it, so you gotta start again.

YOu missed the point, which is simply: you are using the wrong tool for
this project. If it is to learn sketchup it is OK. If you want to create
an image, you should reconsider.

I haven't played with Sketchup. What's it good at?

Can you not edit the vertex positions of the hole? I would say in Blender
just select the vertices or edges of the hole and then translate/scale
them - I can't believe the same isn't possible in even a very basic 3D tool.

Yeah, figures.
Although, as I said, I've used a lot of 3D editors, and SketchUp is at
least the first one good enough to make nontrivial objects with. I
suppose that's something. (It *really* annoys me that it can't do real
curves though...)

Oh, you *can* move the individual points or edges around if you like.
But if your surface is particularly complicated, this becomes
intractably difficult extremely fast. Nowhere near as easy as just
moving the shape around before you make the cut.

Quickly throwing together moderately complex 3D objects. Particularly
ones with lots of straight lines. (E.g., buildings, machinery, tools, etc.)
There's a bunch of tutorial videos on Google's website. For example, in
one a guy spends 10 minutes tracing a (very complicated) CAD drawing of
a building interior. Trace it in 2D, extrude into 3D, cut out a few
rectangular doors and windows, in about 30 minutes total you have a true
3D model of the main parts of this house...
It's great fun, but frustratingly hard to do certain things.
