Carving out a chair
-
Hello again, I'm learning fast, and getting better. I even began working on converting a funky little airplane design I had into a 3d model. You can see the WIP photos. But I'm having a tough time with the stupid pilot seat. I have the basic outside shape created. And then I created another, similar shape, but slightly smaller so that I could use it to carve out the desired interior from the larger chair shape.... didn't work.
When I intersect the two groups, I am only able to get two results. The smaller shape will carve out the interior, but it won't leave any lines indicating where the bottom of the smaller shape was... or if I make the cut-out shape wider than the chair, It will give me the bottom okay, but completely eliminates the chair sides. Neither one works. Rather, what I want is the combined result of both failed methods.
What am I doing wrong? I watched the video tutorials and I think I'm doing it the way they say... but it's still not working.
I've attached the skp file if any of you are willing to inspect my work.

Cant you just push/pull the chairs profile as far as you need?

Yep, that's how I built it originally. But, I had wanted to learn how to do it using the intersection method and by literally carving a shaped piece out of it.
Anyway, I figured it out. I needed to ungroup each element before intersecting them. Once I did that, I was able to keep the profile lines of the back of the insert piece within the chair. I also did another way... by going back to the original profile and cutting the thickness of the bottom and back into the shape. Then I pushpulled the separate pieces till I had both sides and the bottom. Then deleted the inner excess.

Well, esson learned; the intersection lines are always created in the context you are in. If there are two groups and you are outside their context and you make an intersection, the newly created lines will be outside the groups so they won't create faces within the groups.
